      This important work reports on the transcriptomic analysis of leukocytes in the brain of adult zebrafish. A specific novel finding is the identification of dendritic cells distinct from microglia or macrophages; regional distribution of these subsets is described using transgenic lines and immunhistochemistry. The dependence of these subsets of specific transcription factors or receptors is addressed with mutants. This is a thorough and compelling analysis, of interest for scientists using the zebrafish models for neurology, immunology, and infectiology, as well as for those interested in the evolution of the brain and immune system.

      Shore et al. report important findings on the impact of a gain-of-function mutation (Y777H) in the Kcnt1 gene on ion currents and firing behavior in both excitatory and inhibitory neurons in the mouse cortex. The KCNT1 gene encodes a subunit of the Na+-activated K+ (KNa) channel, and the authors substantiate their claims with solid evidence from electrophysiological patch-clamp recordings of dissociated cortical neurons. Nevertheless, the majority of reviewers recommended additional studies to reinforce key findings, proposing the replication of experiments using a more physiologically intact preparation, such as an ex vivo slice.

      This important study presents the first comprehensive catalog of the large neurons that compute optic flow in any insect. The morphological reconstructions from volume electron microscopy of the large arbors of these neurons, the Lobula Plate Tangential Neurons, were followed by the examination of their spatial arrangement to estimate their individual receptive fields and predict their optimal motion sensitivity. This compelling, rigorous data set, which includes the synaptic connectivity of the neurons under study with major target neurons in the fly brain, establishes a foundation for future studies on visual processing on the basis of a known connectome plus genetic driver lines to manipulate its constituent neurons. It will be of interest beyond insect vision to those studying sensory processing and neural circuit function.

      This important study provides convincing evidence of artifactual calcium micro-waves during calcium imaging of populations of neurons in the hippocampus using methods that are common in the field. The evidence that this artifact occurs in the data is convincing; however, the evidence for the particular conditions under which the calcium waves occur is incomplete. The work raises awareness of these artifacts so that any research labs planning to do calcium imaging in the hippocampus can avoid them by using alternative strategies that the authors propose.

    1. eLife assessment

      This study presents a valuable confirmation of the roles of Dact1 and Dact2, two factors involved in Wnt signaling, during zebrafish gastrulation and craniofacial development. The limitation of the study is that its examination of genetic interactions with other Wnt factors does not conclusively distinguish primary from secondary effects for each factor. Addressing this weakness is essential for supporting claims on interactions between dact1/2 and any Wnt factors examined. The findings of a new potential target of dact1/2-mediated Wnt signaling are potentially of value; however, experimental evidence supporting the veracity of this finding is incomplete due to an apparent lack of reproducibility.

      Urofacial syndrome is a rare early-onset lower urinary tract disorder characterized by variants in HPSE2, the gene encoding heparanase-2. This valuable study demonstrates that AAV9-based gene therapy for urofacial syndrome is feasible and safe, at least over the time frame evaluated, with restoration of HPSE2 expression leading to re-establishment of evoked contraction and relaxation of bladder and outflow tract tissue, respectively, in organ bath studies. The evidence supporting these findings is solid, although the analysis would benefit from evaluation of additional replicates for several endpoints, quantitative assessment of HPSE2 expression, inclusion of in vivo analyses such as void spot assays or cystometry, more rigorous assessment of viral integration, and single-cell analysis of the urinary tract in mutants versus controls, all of which make the analysis of the data currently incomplete.

      P-glycoprotein is a major ABC-transporter that exports drugs used in chemotherpay and effects the pharmacokinetics of other drugs. Here the authors have determined cryo-EM structures of drug complexes in previously unforeseen outward-facing conformations. These convincing findings are mechanistically important and reveal potential regions to be exploited by rational-based drug design.

    1. eLife assessment

      This is an important follow-up study to a previous paper in which the authors reconstituted CO2 metabolism (autotrophy) in Escherichia coli. Here, the authors define a set of just three mutations that promote autotrophy, highlighting the malleability of E. coli metabolism. The authors make a convincing case that mutations in pgi are loss-of-function mutations that prevent metabolic efflux from the reductive pentose phosphate autocatalytic cycle, and their data suggest possible roles of mutations in two other genes - crp and rpoB. This research will be particularly interesting to synthetic biologists, systems biologists, and metabolic engineers aiming to develop synthetic autotrophic microorganisms.

      Efforts to increase the representation of women in academia have focussed on efforts to recruit more women and to reduce the attrition of women. This study - which is based on analyses of data on more than 250,000 tenured and tenure-track faculty from the period 2011-2020, and the predictions of counterfactual models - shows that hiring more women has a bigger impact than reducing attrition. The study is an important contribution to work on gender representation in academia, and while the evidence in support of the findings is solid, the description of the methods used is in need of improvement.

    1. eLife assessment

      This study defines a fundamental aspect of protein kinase signalling in the protist parasite Toxoplasma gondii that is required for acute and chronic infections. The authors provide compelling evidence for the role of SPARK/SPARKEL kinases in regulating cAMP/cGMP signalling, although evidence linking the loss of these kinases to changes in the phosphoproteome is incomplete. Overall, this study will be of great interest to those who study Toxoplasma and related apicomplexan parasites.

    1. eLife assessment

      This study presents a valuable finding on how lentiviral infection has driven the diversification of the HIV/SIV entry receptor CD4. Using a combination of molecular evolution approaches coupled with functional testing of extant and ancestral reconstructions of great ape CD4, the authors provide solid evidence to support the idea that endemic simian immunodeficiency virus infection in gorillas have selected for gorilla CD4 alleles that are more resistant to SIV infection. However, this conclusion would be supported more strongly with additional functional testing of other great ape CD4 relative to human and ancestral sequences. Additionally, given the difficulty in definitively proving drivers of selection, the current title of the study is considered an overstatement relative to the data presented.

    1. eLife assessment

      This study presents evidence that suggests that the coalescence of sister chromatids induced by global double-strand DNA breaks (DSBs) during late mitosis is mediated by cohesin SMC3. These findings are valuable for studying the mechanism of eukaryotic cells to repair DNA during late mitosis. Although the discrete DSB induction system in budding yeast is sound, the strength of evidence is incomplete and could be buttressed to better support the major claims and to represent a clear advance with respect to the authors' previous contributions to this field.

      This manuscript offers valuable information on the effect of two small molecule combinations (2C), CHIR99021 and A-485, during the reprogramming of mature cardiomyocytes into regenerative cardiac cells. This manuscript is incomplete, as the mechanistic insights derived from transcriptomic and genomic datasets are without experimental validation. This manuscript also needs additional experimental support to confirm the regenerative potential of 2C and improvements in the data analysis and presentation. Overall, this interesting work provides insights into the development of therapeutic targets for cardiac regeneration in infarcted hearts.

    1. eLife assessment

      The study elucidates a detailed molecular mechanism of the initial stages of transport in a medically relevant GABA neurotransmitter transporter GAT1 and thus generates useful new insights for this protein family. In particular, it presents convincing evidence for the presence of a "staging binding site" that locally concentrates Na+ ions to increase transport activity, whilst solid evidence for how Na+ binding affects the larger scale dynamics.

    1. eLife assessment

      This study provides fundamental new knowledge into the role of reversible cysteine oxidation and reduction in protein kinase regulation. The data provide convincing evidence that intra-molecular disulfide bonds serve a repressive regulatory role in the Brain Selective Kinases (BRSK) 1 & 2; part of the as yet understudied 'dark kinome'. The findings will be of broad interest to biochemists, structural biologists, and those interested in the rationale design and development of next-generation kinase inhibitors.

    1. eLife assessment

      The authors use a powerful combination of phylogenetics, structure prediction, biochemistry, and mutagenesis to provide an understanding of the mechanism that provides target specificity of Drosophila HP1 homolog Rhino vs. HP1, with Rhino specifically binding to piRNA loci. The authors show that a single amino acid substitution in the chromodomain of Rhino allows binding of the zinc finger protein Kipferl, which directs the complex to a subset of heterochromatic regions that other HP1 homologs do not. The evidence supporting the conclusions is compelling, providing an impressive level of mechanistic understanding of how the specificity of the piRNA genome defense system is defined. Also, the study highlights how a single amino acid change can change the functionality of a protein, providing fundamental insight into protein evolution.

    1. eLife assessment

      Using genomic data from ancient and modern samples, this important study investigates the genomic history of cattle in Iberia, focusing on the admixture between domestic cattle and their wild ancestors, aurochs. The authors present solid evidence for interbreeding between domestic cattle and wild aurochs since the Neolithic period, although the extent, sex bias, and directionality of genetic flow over time remain highly unclear. The authors also show that the aurochs ancestry in cattle stabilized at ~20% since ~4000 years ago and continues into modern breeds, including the Lidia breed that is bred for aggressiveness and used in bullfighting. The work will be of interest to evolutionary biologists and quantitative geneticists who seek to understand the genomic history and genetic basis of trait variation of domesticated animals.

      This useful study, which is of potential interest to a broad readership as it systematically addresses off-target effects of a commonly used chemotherapy drug on bone and bone marrow cells, presents evidence that reducing systemic inflammation induced by doxorubicin limits to some extent bone loss. Unfortunately, the work does not inform sufficiently on the mechanisms of doxorubicin action on bone, although the demonstration of the effect of systemic inflammation on bone loss is convincing. While this finding is not new, additional genetic and pharmacologic experiments and a deeper analysis of the bone phenotype would improve our understanding of what the mechanisms involved in doxorubicin-induced bone loss are, and may substantiate the clinical relevance of targeting inflammation in order to limit the negative impact of chemotherapies on bone quality.

    1. eLife assessment

      This study follows the career trajectories of the winners of an early-career funding award in the United States, and finds that researchers with greater mobility, men, and those hired at well-funded institutions experience greater subsequent funding success. Using data on K99/R00 awards from the National Institutes of Health's grants management database, the authors provide compelling evidence documenting the inequalities that shape faculty funding opportunities and career pathways, and show that these inequalities disproportionately impact women and faculty working at particular institutions, including historically black colleges and universities. Overall, the article is an important addition to the literature examining inequality in biomedical research in the United States.

    1. eLife assessment

      This study examines the human voltage-gated chloride channel CLC-2. A combination of cryo-EM, electrophysiology, and computational analysis provides compelling support for a "ball and chain" mechanism of inactivation. This and other findings regarding the gating and inhibition mechanisms of the channel are of fundamental interest to ion channel physiologists.

    1. eLife assessment

      The paper addresses the mechanism of initiation of DNA replication in human cells by analyzing published data on the location of origins of DNA replication and the location of binding sites in the genome for ORC and MCM2-7 complexes. There are some useful analyses of existing data but there are concerns regarding the conclusion that there might be alternative mechanisms for determining the location of origins of DNA replication in human cells compared to the well known mechanism known from many eukaryotic systems, including yeast, Xenopus, C. elegans and Drosophila. The lack of overlap between binding sites for ORC1 and ORC2, which are known to form a complex in human cells, is a particular concern and points to the evidence for the accurate localization of their binding sites in the genome being incomplete.

    1. eLife assessment

      By developing a novel method for detecting genetic variants associated with germline mutation spectrum variation, this important study identifies a new "mutator" locus in a population of inbred mouse strains, although the causal gene(s) and allele(s) within this locus remain uncertain. The authors further demonstrate that this new mutator locus interacts epistatically with a previously identified mutator allele on C>A mutation rate, showcasing the complexity of the genetic basis underlying variation in mutation rate and spectrum. Evidence for major findings in this paper is convincing, and the new method has the potential to be applicable to a variety of experimental systems and natural populations.

      This valuable manuscript by Go et al. provides an interesting account documenting the role of resident CD56(br) NK cells in driving interaction with DCs that attract CD8+ T cells to the pancreas cancer tumor microenvironment (TME). The work convincingly illustrates how irradiation combined with CCR5i and PD1 blockade leads to a reduction in pancreatic cancer growth that correlates with a reduction in Tregs and enhancement of NK and CD8 T cells in the TME. The correlation of NKC1 signature with survival in pancreatic cancer patients is indeed of broader interest regarding potential relevance to other types of cancer.

    1. eLife assessment

      This study discloses important physiological function for TMEM63 in regulating postnatal growth in mice. The data supporting the impaired body growth and skeletal phenotype as well as disrupted growth hormone/insulin-like growth factor-I (GH/IGF-I) signaling in TMEM63 knockout mice are compelling. However, to establish that alteration of hepatic GH/IGF-I signaling is the cause for observed growth and skeletal phenotype in TMEM63 knockout mice would need additional work.

    1. eLife assessment

      The authors' findings have theoretical or practical deep implications, which makes them important. The methods, data, and analyzes support the authors' arguments with only minor weaknesses, and overall they are solid. In vitro culture experiments could provide evidence to strengthen the evidence for the functional significance of Th1-mediated cytokines in the observed B cell responses.

    1. eLife assessment

      This important study advances the understanding of physiological mechanisms in deep-sea Planctomycetes bacteria, revealing unique characteristics such as the only known Phycisphaerae using a budding mode of division, extensive involvement in nitrate assimilation, and release phage particles without cell death. The study uses convincing evidence based on experiments using growth assays, phylogenetics, transcriptomics, and gene expression data. The work will be of interest to bacteriologists and microbiologists in general.

    1. eLife assessment

      This study presents a computational model to explore how neurostimulation could impact hippocampal theta oscillations. The computational model combines a detailed physiologically realistic hippocampus model and an abstract theta oscillator. The study could provide valuable predictions on pathological changes in this network. The modelling is based on convincing approaches that could be improved with experimental validation in future experiments.

    1. eLife assessment

      This paper reports the development of SCA-seq, a new method derived from PORE-C for simultaneously measuring chromatin accessibility, genome 3D and CpG DNA methylation. Most of the conclusions are supported by convincing data. SCA-seq has the potential to become a useful tool to the scientific communities to interrogate genome structure-function relationships.

    1. eLife assessment

      This important study reports on the dynamics of PKA investigated at the single-cell level in vitro and in epithelia in vivo. Using different fluorescent biosensors and optogenetic actuators, the authors dissect the signaling pathway responsible for PKA waves, finding that PKA activation is a consequence of PGE2 release, which in turn is triggered by calcium pulses, requiring high ERK activity. The evidence supporting the claims is solid. At this stage the work is still partly descriptive in nature, and additional measurements would increase the strength of mechanistic insights and physiological relevance.

    1. eLife assessment

      This study has important implications for theoretical proposals concerning how language lateralization affects the lateralization of other cognitive functions. The methods are solid, with an appropriate selection of cognitive control tasks that share homotopic regions of the brain with language, comparing participants with typical and atypical organization of language. The participants included in the study were mainly bilinguals, a population previously reported to have a more bilateral organization of cognitive control regions than monolinguals, limiting the generalizability of the results to the general population. Despite this limitation, the results will be of interest to researchers working of brain plasticity and development, in addition to those interested in language and cognitive control.

    1. eLife assessment

      The authors propose that the asymmetric segregation of the NuRD complex in C. elegans is regulated in a V-ATPase-dependent manner, that this plays a crucial role in determining the differential expression of the apoptosis activator egl-1, and that it is therefore critical for the life/death fate decision in this species. If proven, the proposed model of the V-ATPase-NuRD-EGL-1-Apoptosis cascade would shed light onto the mechanisms underlying the regulation of apoptosis fate during asymmetric cell division, and stimulate further investigation into the intricate interplay between V-ATPase, NuRD, and epigenetic modifications. However, the strength of evidence for this is currently incomplete.

    1. eLife assessment

      This paper presents important findings into the response of epithelial monolayers to the combined effects of surface curvature and hydraulic stress, offering insights into how these cues contribute to epithelial cell extrusion. Most of the evidence is convincing, relying mainly on a combination of imaging-based techniques. This paper is of interest to a broad and growing community of biologists, biophysicists, and engineers interested in cell-geometry interactions.

    1. eLife assessment

      The authors use a combination of structural and MD simulation approaches to characterize phospholipid interactions with the pentameric ligand-gated ion channel, GLIC. The general agreement between structures and simulations increases confidence in the description of the lipid interaction poses and provides a solid basis for the prediction of a state-dependent interaction site where lipids could dynamically modulate channel gating. The results will be very useful to understand the nature of phospholipid interactions with pentameric ligand-gated ion channels, although the functional or structural significance of these lipid interactions remains to be verified.

    1. eLife assessment

      In this study, neurons were recorded and combined across the parahippocampal area while rats performed a memory-guided spatial navigation task. Sophisticated analytical tools were used to provide convincing evidence that neuronal populations in these areas show behavior-related changes that might indicate the encoding of errors by the system. The valuable results suggest that rate remapping is a likely mechanism to support changes in representations that support memory-guided behavior in these regions, most interestingly in neurons that code head direction.

    1. eLife assessment

      This is a potentially important study that deals with the toxic effects of an intermediary in lipid degradation [trans-2-hexadecenal (t-2-hex)] in yeast through modification of mitochondrial protein import via the TOM complex. However, in the current version, the claims are incompletely supported by the data. Lacking is evidence that Tom40 is a direct target of the lipid derivative or causally implicated in the described consequences. Were such evidence forthcoming, the paper would be interesting to a broad audience of molecular and cell biologists.

    1. eLife assessment

      This important study reports on the causal role of the inferior frontal gyrus (IFG) in behavioral control. Transcranial ultrasonic stimulation is used to stimulate the IFG in a stop-signal task. The results are compelling while the analyses remain incomplete and some claims are unsubstantiated.

    1. eLife assessment

      This is an important biophysical study combining native mass spectrometry with mutant cycles to estimate the thermodynamic components of lipid A binding to the ABC transporter MsbA. Solid evidence supports the binding energies for lipid-protein interactions to MsbA using this approach, which could be later applied to other membrane proteins in general.

    1. eLife assessment

      This manuscript characterized signaling pathways for growth control and aflatoxin production in the important plant pathogen Aspergillus flavus. Associating tor and tapA with the control of aflatoxin production would be important. However, the copy number of the tor and tapA genes needs to be more clearly established, and without such work, the evidence remains incomplete.

    1. eLife assessment

      This study presents valuable insights into the evolution of the gasdermin family, making a strong case that a GSDMA-like gasdermin that was activated by caspase-1 cleavage was already present in early land vertebrates. Convincing biochemical evidence is provided that extant avian, reptile, and amphibian GSDMA proteins can still be activated by caspase-1 and upon cleavage induce pyroptosis-like cell death - at least in human cell lines. The caspase-1 cleavage site is only lost in mammals, which use the more recently evolved GSDMD as a caspase-1 cleavable pyroptosis inducer. The work will be of considerable interest to scientists working on the evolution of cell death pathways, or on cell death regulation in non-mammalian vertebrates.

    1. eLife assessment

      This important research uses an elegant combination of protein-protein biochemistry, genetics, and microscopy to demonstrate that the novel bacterial protein FipA is required for polar flagella synthesis and binds to FlhF in multiple bacterial species. This manuscript is convincing, providing evidence for the early stages of flagellar synthesis at a cell pole; however, the protein biochemistry is incomplete and would benefit from additional rigorous experiments. This paper could be of significant interest to microbiologists studying bacterial motility, appendages, and cellular biology.

    1. eLife assessment

      This important study characterizes various cell populations and describes a developmental trajectory using snRNAseq data, highlighting the cell state transitions including periosteal stem cells during bone repair. However, there was a general consensus that the evidence provided is currently incomplete, necessitating the additional data and a more thorough verification of the conclusions. Despite this, the work provides a helpful resource that will be of broad interest to the bone community.

    1. eLife assessment

      This valuable study investigates the implementation of an efference copy mechanism in the visual flight control system of Drosophila, a topic of broad interest to sensorimotor neuroscientists. Although the behavioral data and computational analysis are solid, the lack of physiological data, as well as the absence of flight saccades in the model, provide incomplete support for the paper's conclusions.

    1. eLife assessment

      The work by O'Reilly and Delis is important to extend the synergy ideas using methods from signal processing and information theory to cluster muscles and task parameters, thereby advancing our understanding of the modular architecture of motor control. The method is innovative, and the findings are compelling from theoretical and practical perspectives. The work will be of broad interest to motor control and neural engineering researchers.

    1. eLife assessment

      This study presents valuable new structures of a carbamylation-mimetic K125E mutant of the Cx26 gap junction channel uncovering the cytoplasmic loop structure and information about the closed state of the channel. The cryo-EM maps are in high quality and serve as strong foundations for dissecting the gating mechanism by CO2. However, incomplete functional studies fall short of supporting the proposed mechanism of gap junction channel modulation through carbamylation.

    1. eLife assessment

      This important study identifies candidate mitochondrial metabolite carriers in stramenopile protists that may allow these divergent eukaryotes to maintain a compartmentalized glycolytic pathway. This study fills a gap in our understanding of glycolysis evolution and opens avenues for drug design to combat stramenopile parasites. The evidence, based on phylogenetic analysis, thermostability shift assays, and in vitro reconstitution of transport reactions, is convincing, albeit lacking direct in vivo confirmation of the physiological function of these candidates.

    1. eLife assessment

      This fundamental study provides insight into the fascinating process of self- and non-self-recognition in the protist Tetrahymena thermophila, a species with seven distinct mating types. Using an elegant combination of phenotypic assays, protein studies, and imaging, the authors present convincing evidence that a large multifunctional protein complex at the cell surface mediates both self- and non-self mating-type recognition. This study extends our understanding of how more than two mating types/sexes may be specified in a species, and it will be relevant for anyone interested in sexual systems and cell-cell communication.

    1. eLife assessment

      This valuable study demonstrates the requirement of a DEAD-box helicase DDX6 for the cotranslational mRNA decay pathway in human cells. The authors performed a set of solid experiments, combining DDX6 KO cells with reporter assay and global analysis of mRNA stability/translation efficiency. Although some conclusions drawn by the authors need a more careful examination of alternative possibilities, this study will be of broad interest to RNA biologists working on translational control and mRNA stability.

    1. eLife assessment

      In this valuable paper, the authors use an existing theoretical framework relying on information theory and maximum entropy inference in order to quantify how much information single cells can carry, taking into account their internal state. They reanalyze experimental data in this light. Despite some limitations of the data, the study convincingly highlights the difference between single-cell and population channel capacities. This result should be of interest to the quantitative biology community, as it contributes to explaining why channel capacities are apparently low in cells.

    1. eLife assessment

      This study provides useful insights into the subcellular localization, interaction with integrins, and functional importance of the cell surface receptor Piezo1 in migrating human T-cells. Whether Piezo1 is critically sensing mechano-physical cues during T-cell migration is however not well supported by direct experimental evidence. The data collected is solid otherwise.

    1. eLife assessment

      This important study uses the novel light sheet imaging technique to investigate how different TLR4 agonists regulate Myddosome formation. The data showing that LPS and A-beta can control the kinetic and size of Myddosome assembly are compelling. This work would further benefit from establishing the linkage between these results and downstream signal efficiency. With this aspect strengthened, this paper would be of great interest to the innate immunity field.

    1. eLife assessment

      Following small molecule screens, this study provides convincing evidence that 7,8 dihydroxyflavone (DHF) is a competitive inhibitor of pyridoxal phosphatase. These results are important since they offer an alternative mechanism for the effects of 7,8 dihdroxyflavone in cognitive improvement in several mouse models. This paper is also significant due to the interest in the phosphatases and neurodegeneration fields.

    1. eLife assessment

      Therapeutic treatments for congenital and acquired craniofacial (CF) bone abnormalities are not well developed. This study provides convincing evidence for an innovative regenerative treatment for pediatric craniofacial bone loss using Jagged1-PEG-MAL hydrogel with pediatric human bone cells. The report is a valuable advance in this field.

    1. eLife assessment

      TRPV4 is a unique cation channel that has been demonstrated to play a role in a variety of sensory processes. The authors provide useful new data to indicate that TRPV4 activation occurs in eccrine gland cells. They then show that temperature-dependent perspiration is TRPV4-dependent in mouse skin. This provides new insight, but the data are incomplete in that more orthogonal assays could be used to more comprehensively support the conclusions.

      This so-far most comprehensive, spatially resolved in 2D, dynamical, multicellular model of murine muscle regeneration after injury is is an attempt to combine many contributors to muscle regeneration into one coherent calibrated framework. It has the potential to be a very valuable tool in the areas of tissue morphogenesis, regenerative therapies, quantitative modeling and simulation. However, the presentation of the experimental validation is incomplete.

    1. eLife assessment

      This study offers useful insights into the structural architecture of the mammalian egg-sperm fusion synapse, shedding light on the role of specific proteins in fertilization. The strength of the findings lies in the potential identification of a pentameric complex involved in gamete fusion by utilizing a new multimer structure prediction tool, AlphaFold Multimer. The absence of experimental validation weakens the strength of evidence supporting these claims and leaves this work incomplete.

    1. eLife assessment

      This study presents a valuable model for the emergence of planar cell polarity from the interplay of local interactions and global gradient. The framework of this model is solid, although the appreciation of its result should in places be more quantitative. A quality of this model is its simplicity and its convenience for experimental testing.

    1. eLife assessment

      This useful study introduces the development of Salmonella infection model in zebrafish embryos as an important model to study the interaction between macrophages and Salmonella during in vivo infection. Overall, the data presented are convincing and provide an inventory of genes mediating macrophage cell-cell adhesion and interactions that are useful for dissecting tissue macrophage responses and heterogeneity during intracellular bacterial infection. This is important to characterize the infection outcome and the dynamics of the immune response. The work will be of interest to microbiologists.

    1. eLife assessment

      This paper makes a valuable contribution to approaches to studying the stimulus selectivity of sensory neurons. The imaging data that forms the core of the paper is compelling, but the evidence for some of the conclusions reached is limited. A central issue is a reliance on linear measures of stimulus selectivity, which may miss key aspects of retinal coding.

    1. eLife assessment

      This valuable study addresses both commonly accepted and alternative hypotheses for the mechanism by which an intercrop supports pest control in push-pull agriculture, a promising and broadly recognized approach for sustainable intensification. The findings address a widely recognized gap in data on the mechanism underlying push-pull systems and thus can be important for work on pest control in agroecology as well as plant-herbivore interactions more generally. The support of claims is solid, combining observations of several different mechanistic aspects in an uncommonly broad range of relevant environments with clear reasoning regarding experimental design, but also using some non-standard approaches that are not as well explained, complicating comparisons to the current state of the art.

    1. eLife assessment

      This paper is of interest to a broad audience of cell biologists, and researchers who work in cell death and the role of NETosis in the pathogenesis of chronic diseases. This study presents valuable new insights to support NETosis plays an important role in the development of aristolochic acid nephropathy (AAN). A series of compelling experiments using in vivo and in vitro model supported that AAN induced NET formation via IL-19-IL20-beta receptor can induce inflammation and cell death. This new knowledge of the interaction between kidney cells and neutrophils could have clinical implications in the treatment of AAN.

    1. eLife assessment

      In this manuscript the authors describe the expression and regulatory function of a self-cleaving ribozyme in the Cpeb3 gene. This is an important study because although many self-cleaving ribozymes have been identified in the genome, the functions of these RNA enzymes even for molecular control of their target genes is mostly unknown. The manuscript provides solid data for the molecular function of the ribosome in gene regulation and its role in hippocampal learning. The study will be of interest to neurobiologists who study gene regulatory mechanisms in learning.

      (Summary generated with Kagi's Universal Summarizer.)

      Bandcamp has operated as an online music store for over a decade, providing artists and labels with an easy-to-use platform to sell music directly to fans. While receiving little mainstream attention, Bandcamp has paid out $270 million to artists and maintained a simple, artist-focused design. The platform allows free streaming but encourages direct purchases from artists. Chance the Rapper has been a notable champion of Bandcamp, using it for early mixtapes and helping to bring attention to its role in supporting independent musicians. While other services focus on algorithms and playlists, Bandcamp prioritizes direct artist support through low fees and transparent sales data. It has changed little over the years but provides a niche alternative for direct fan-artist connections without the culture-diluting aspects of other streaming services. Bandcamp's low-key approach has helped it avoid issues faced by competitors while continuing to innovate for artists.

    1. eLife assessment

      The finding that Fusicoccin (FC-A) promotes locomotor recovery after spinal cord injury is supported by solid data, and the idea of harnessing small molecules that may affect protein-protein interactions to promote axon regeneration is valuable. The evidence showing that 14-3-3 and spastin interact and that 14-3-3 enhances spastin function and stability in cells is also solid.

    1. eLife assessment

      This valuable paper examines gene expression differences between male and female individuals over the course of flower development in the dioecious angiosperm Trichosantes pilosa. Male-biased genes evolve faster than female-biased and unbiased genes, which is frequently observed in animals, but this is the first report of such a pattern in plants. In spite of the limited sample size, the evidence is mostly solid and the methods appropriate for a non-model organism. The resources produced will be used by researchers working in the Cucurbitaceae, and the results obtained advance our understanding of the mechanisms of plant sexual reproduction and its evolutionary implications: as such they will broadly appeal to evolutionary biologists and plant biologists.

      This valuable study reports the induction of supernumerary inner hair cells in the mouse cochlea upon reducing the expression level of a tight-junction protein (claudin-9). However, the evidence supporting the claims is incomplete and the work would be strengthened by adding several control experiments, resolving inconsistencies and imprecisions in the presentation of the results, and providing more mechanistic insight. The work will be of interest to scientists working in the development and regeneration of hair cells in the inner ear.

    1. eLife assessment

      This important study used a new double knockout mouse model to investigate the role of two neuropeptides, substance P and CGRPa, in pain signaling. There is convincing evidence that double knockout of these two molecules, both of which have historically been associated with pain, does not affect nociception or acute pain behaviors in males and females. The conclusions would further benefit from additional validation of the approach, consideration of potential outliers and statistical approach in cases with smaller sample sizes, and consideration of the potential for opposing effects across region or peptide. This paper will be of interest to those interested in the neurobiology of pain and/or neuropeptide function.

      Yang et al. investigate whether distinct sources of conflict are represented in a common cognitive space. The study uses an interesting task that mixes different sources of difficulty and reports that the brain appears to represent these sources as a mixture on a continuum in prefrontal areas. While the findings could be valuable to theory in this area, there are concerns with the analysis, design and results, that raise uncertainty regarding the main conclusion of a shared cognitive space. Thus, the evidence reported here ranges from solid to incomplete.

The issue of generalisation is a core topic in neuroscience and psychology, relevant across a wide range of areas, and the findings will be of interest to researchers across areas in perception, learning, and cognitive science. The findings have the potential to provide compelling support for the outlined account, but there appear other possible explanations, too, that may affect the scope of the findings but could be considered in a revision.

    1. eLife assessment

      This valuable study links the "taste" of botanicals to their application as medicines used by the ancient Greco-Roman society. The authors used phylogenetic linear mixed models in a Bayesian framework to test the relationships between taste qualities, intensities, complexities, and therapeutic use. The evidence supporting the conclusions is solid, although there is a minor weakness concerning the somewhat inconsistent method of botanical preparation and presentation to the taster panelists; subjective bias and robustness of the participants' responses might have been overlooked. The study may be of broad interest to pharmacologists and scientists working on drug discovery, particularly those interested in natural products.

    1. eLife assessment

      This fundamental study provides compelling evidence to explain how chemical variations within a set of kinase inhibitors drive the selection of specific Erk2 conformations. Conformational selection plays a critical role in targeting medically relevant kinases such as Erk2 and the findings reported here open new avenues for designing small molecule inhibitors that block the active site while also steering the population of the enzyme into active or inactive conformations. Since protein dynamics and conformational ensembles are essential for enzyme function, this work will be of broad interest to those working in drug development, signal transduction, and enzymology.

      This work shows for the first time that the balance of mTOR (mTORC1 and mTORC2) in Sertoli cells regulates the rate of sperm epigenetic aging. The manuscript presents valuable findings that have some theoretical and practical implications. The strength of the evidence is however incomplete: they are limited in some places and the aims are not always fully supported by the results.

    1. eLife assessment

      The main idea tested in this work is that host galectin-9 inhibits Mycobacterium tuberculosis (Mtb) growth by recognizing the Mtb cell wall component arabinogalactan (AG) and, as a result, disrupting mycobacterial cell wall structure. Moreover, a similar effect is achieved by anti-AG antibodies. While the hypothesis is intriguing and the work has the potential to make a valuable contribution to Mtb therapy, the evidence presented is incomplete and does not explain several critical points including the dose-independent effect of galectin-9 on Mtb growth and how anti-AG antibodies and galectin-9 access the AG layer of intact Mtb.

    1. eLife assessment

      This study offers a useful advance by introducing a cord blood DNA methylation score for maternal smoking effects, with the inclusion of diverse cohorts. However, the overall strength of evidence is deemed incomplete, due to concerns regarding low exposure levels, low statistical power, potential overfitting, and the need for clearer descriptions of statistical methods. Building more directly from the existing evidence base, exploring differences between ancestries, and considering additional health outcomes would help to enhance the study.

      This important study presents the validation of an oral delta9-tetrahydrocannabinol (THC) consumption mouse model utilizing highly palatable e-capsule gelatin. The results convincingly demonstrate that oral consumption produced THC behavioral and physiological effects, as well as measurable brain levels. The utility of the model for chronic consumption remains to be determined. The authors have clearly acknowledged limitations of their model and areas for future study and development. As the field of cannabinoid research moves toward application of routes of administration that mimic human use, these model systems will be pivotal in assessing the effects of cannabinoid-based drugs.

    1. eLife assessment

      Focusing mainly on var genes, the investigators performed comprehensive computational analyses of gene expression in malaria parasites isolated from patients and assessed changes that occur as these parasites adapt to in vitro culture conditions. The study provides an improved computational pipeline for monitoring var gene expression, and importantly, the study documents changes in expression of the core genome and thus provides insights into metabolic adaptations that parasites undergo while transitioning to culture conditions. The findings are important for their technical advances that are more rigorous than the current state-of-the-art. The solid data analyses, broadly support the claims with only minor weaknesses, tell us to be cautious when interpreting results obtained only from cultured parasites.

    1. eLife assessment

      This valuable study highlights how the diversity of the malaria parasite population diminishes following the initiation of effective control interventions but quickly rebounds as control wanes.

    1. eLife assessment

      This valuable study introduces a new simulation model to explain the wide-spread occurrence of genetic inversions in fruit-fly genomes, based on sexually antagonistic alleles and a trade-off between male reproduction and survival. The evidence supporting the conclusions is currently incomplete, but it might be possible to address this with additional simulations and experiments as well as more rigorous analysis of the model and the data. The work will be of interest to population geneticists beyond the fruit-fly system.

    1. eLife assessment

      The manuscript presents an analysis of different factors that are required for release of the lipid-linked morphogen Shh from cellular membranes., which will be useful in the field.

This work will be of interest to those studying DNA replication and investigating protein-DNA interactions across the genome.

    1. eLife assessment

      This investigation of the changes in gene expression and some of the physiological consequences of sublethal exposures to the neonicotinoid insecticide imidacloprid in honeybee larvae is useful, although numerous experiments were not considered based on technical issues. The methodological design leads to concerns and it is therefore not obvious that all conclusions are justified. The study adds to our understanding of how this insecticide impacts development and growth of honeybees, but the evidence supporting the major claims is incomplete.

    1. eLife assessment

      This important study furthers our understanding of the antimicrobial properties of siderophores, and their potential use to battle opportunistic pathogens. The evidence supporting the conclusion is solid, based on rigorous biochemical, growth, and virulence assays.

The work will be of broad interest to colleagues in the fields of evolutionary ecology, microbiology, and medical sciences.

    1. eLife assessment

      This important study uses an innovative set of reporter assays to probe the role of the TnpB protein in IS608 transposition. The work provides independent support for the recently reported homing activity of TnpB, where the transposon is restored following excision, and suggests an additional function for TnpB in enhancing the transposase activity of the TnpA transposase. The overall approach is solid, but the authors should consider how the activity of the TnpB protein used, or the levels of ωRNA, impact their model.

    1. eLife assessment

      The manuscript offers useful descriptive insights into the potential influence of whole-brain lactate and pH levels on the manifestation of behavioral phenotypes seen in diverse animal models of neuropsychiatric disorders. However, reviewers have raised concerns about the potential loss of specificity in capturing regional and cell-type-specific effects when relying solely on whole-brain analysis methods. While the evidence supporting the conclusions is largely solid, the robustness of these conclusions could be enhanced by the inclusion of additional data and further analysis.

    1. Editors Assessment: Antimicrobial resistance (AMR) is a global public health threat, and environmental microbial communities can act as reservoirs for resistance genes. There is a need for genomic surveillance could provide insights into how these reservoirs change and impact public health. With that goal in mind this study tested the ability of nanopore sequencing and adaptive sampling to enrich for AMR genes in a mock community of environmental origin. On average adaptive sampling resulting in a target composition 4x higher than without adaptive sampling, and increased target yield in most replicates. The methods and scripts for this approach were reviewed and curated together, although the scope of this study was limited in terms of communities tested and AMR genes targeted. And the authors improved their analysis by conducting an additional analysis of a diverse microbial community. Demonstrating the method is reusable and its results are promising for developing a flexible, portable, and cost-effective AMR surveillance tool.

      George et al. present a convincing new Python toolbox ("RatInABox") that allows researchers to generate synthetic behavior and neural data specifically focusing on hippocampal functional cell types (place cells, grid cells, boundary vector cells, head direction cells).

      This is valuable for theory-driven research where synthetic benchmarks should be used. Beyond just navigation, it can be highly useful for novel tool development that requires jointly modeling behavior and neural data. The authors provide convincing evidence of its utility with well documented and easy to use code and the corresponding manuscript.

    1. eLife assessment

      The authors introduce a potentially valuable novel method that provides trial-by-trial probabilistic estimates of learning and decision-making strategies inferred from choice behavior across species. This approach could prove more useful over traditional techniques for arbitrating between strategies and detecting when learning happens, and because it is computationally lightweight. Reviewers identified several concerns that limit the strength of the evidence provided, rendering the findings incomplete.

    1. eLife assessment

      This important study combines disparate results from both psychophysics and neural silencing experiments to suggest a new interpretation of how animals and humans represent and interpret recent events in our memory. A key aspect of the model put forward here is the presence of discrete jumps in neural activity within the posterior parietal region of the cortex. The model is distinct from other models, and the authors provide convincing evidence to support it both from existing results as well as from novel experiments.

    1. eLife assessment

      This is an important study that develops a method to fluorescently label peptide MHC complexes on live dendritic cells to enable detection of antigen specific T cells in polyclonal populations. Solid evidence that this can be used to effectively identify antigen specific T cells in vitro and in vivo is provided for one model antigen systems (Ova-OTII). The approach has exciting potential as prior single step methods with directly conjugated single peptides have generally failed due to high background. Thus, this approach potentially moves the state of the art forward, but further work is needed to realise and determine the limits and ultimate utility of the approach.

    1. eLife assessment

      The study presents a valuable finding on sexually-dimorphic patterns of osteocyte transcriptomics and low calcium diet-induce bone loss. The evidence supporting the claims of the authors regarding the protective role of Irisin/FNDC5-deficiency in lactation and low-calcium diet in female mice is incomplete, due to the relatively modest phenotypes observed and the insufficient link between Irisin/FNDC5 and calcium homeostasis or milk production.

    1. eLife assessment

      This important study provides novel strategies to overcome certain limitations when investigating the metabolism of hematopoietic stem cells, mainly due to their low abundance. The study provides compelling evidence suggesting that proliferative hematopoietic stem cells mainly use glycolysis (rather than mitochondrial OXPHOS or TCA cycle) as their primary energy source during emergency hematopoiesis. The article provides direct links between metabolic features and cell proliferation and explores alternative energy sources, and is of great interest to stem cell biologists.

    1. eLife assessment

      This is a useful study that shows changes in the chromatin landscape of GABAergic neurons in induced pluripotent stem cells (iPSCs) derived from both Dravet Syndrome (DS) patients and healthy donors. The strength of the evidence is currently incomplete because the authors compared iPSCs from different individuals, rather than isogenic controls, and they did not examine the expression of the gene and encoded protein (SCN1A or Nav1.1) that are thought to be responsible for the majority of DS cases in these iPSCs. The work would be of interest to scientists who study development, developmental disorders, and epigenetic contributions to disease.

    1. eLife assessment

      This important work presents data showing that all non-proneural phenotypes of the Inhibitor of DNA binding (Id) protein emc are mediated through inappropriate non-apoptotic caspase activity. Using the developing Drosophila retina as a model the authors convincingly show that emc acts by transcriptionally regulating the Death-Associated Inhibitor of Apoptosis 1 (diap1) gene, which impacts on Notch signaling by caspase-dependent increase of Delta protein. These findings are interesting for the caspase/apoptosis field as they add more non-apoptotic functions of caspases to the list, as well as for the Id field, which examines how Id proteins inhibit cell differentiation.

    1. eLife assessment

      The work is a valuable contribution to understanding the mechanism of nuclear export of tRNA in budding yeast. The authors present solid evidence that Dbp5 functions in parallel with Los1 and Msn5 in tRNA export, in a manner dependent on Gle1 for activation of its ATPase activity but independently of Mex67, Dbp5's partner in mRNA export. It further presents biochemical evidence that Dbp5 can bind tRNA but that Gle1 and InsP6 are required for activating ATP hydrolysis by the Dbp5-tRNA complex, suggesting a possible mechanism for tRNA export by Dbp5.

      In this valuable manuscript, Yao et al. describe new methods for assessing the intracellular itinerary of Botulinum neurotoxin A (BoNT/A), a potent toxin used in clinical and cosmetic applications. The current manuscript challenges previously held views on how the catalytic portion of the toxin makes its way from the endocytic compartment to the cytosol, to meet its substrates. The approach taken is deemed innovative and the experiments are carefully performed, however, they are somewhat incomplete with respect to the drawn conclusions, as it is possible that the scope of their findings could be restricted to the specific neuron model and molecular tools that were used. This paper could be of interest to both cell biologists and physicians.

      In this study, camera trapping and species distribution models are used to show that human disturbance in mountain forests in the eastern Himalayas pushes medium-sized and large mammal species into narrower habitat space, thus increasing their co-occurrence. While the collected data provide a useful basis for further work, the study presents incomplete evidence to support the claim that increased co-occurrence may indicate positive interactions between species.

    1. eLife assessment

      This fundamental study addresses a long-standing mystery in splicing regulation: does splicing occur co- or post-transcriptionally? The authors provide compelling evidence demonstrating that splicing can occur post-transcriptionally at a transcription site proximal zone, changing the way we think about splicing.

    1. eLife assessment

      This is an important study using 3D mapping of neuronal activation throughout the brain after pair-bonding in the monogamous vole, which can be broadly applied to other species and behaviors. The authors provide compelling evidence that there is some synchrony between male and female partners that have formed a pair bond, the strength of which is based on the number of ejaculations received by the female. Same-sex pairs also form a pair bond and were found to have activation in the same brain regions as mixed sex couples. An overall low level of sex differences in the degree and location of brain activation was observed, which was unexpected. This work will be of interest to those interested in social behavior and its neural mechanisms, or brain systems or behavior more broadly.

    1. eLife assessment

      This important study reports on an improved deep-learning-based method for predicting TCR specificity. The evidence supporting the overall method is compelling, although the inclusion of real-world applications and clear comparisons with the previous version would have further strengthened the study. This work will be of broad interest to immunologists and computational biologists.

    1. eLife assessment

      Studies of synaptic development and plasticity in the nematode C. elegans have been limited by the difficulty of rapid, accurate assessments of synaptic structure. Here, with a series of convincing studies, the authors introduce and validate a valuable computational pipeline, "WormPsyQi," that allows rapid, reproducible quantitation of fluorescent synaptic puncta while minimizing human error and bias. The authors also describe a new set of strains carrying synaptic markers. Together, these tools should provide groups studying this model system with the ability to quantitatively characterize chemical and electrical synapses, even in densely packed regions in 3D space such as the nerve ring.

    1. eLife assessment

      The study is of importance for the cardiac modeling field by developing a novel mathematical model with sex difference. The data are compelling, and the model is helpful for mechanistic understanding, and thus is also important for experimental physiology. The model is based on experimental data and validated against some experimental data.

    1. eLife assessment

      The important work by Aballay et al. significantly advances our understanding of how G protein-coupled receptors (GPCRs) regulate immunity and pathogen avoidance. The authors provide convincing evidence for the GPCR NPR-15 to mediate immunity by altering the activity of several key transcription factors. This work will be of broad interest to immunologists.

    1. eLife assessment

      BMP signaling plays a vital role in skeletal tissues, and the importance of its role in microtia prevention is novel and promising. This important study will shed light on the role of BMP signaling in preventing microtia in the ear. Solid data broadly support the claims with only minor weaknesses.

    1. eLife assessment

      The study has added value to what we have already known in the potential pharmacological immunomodulatory therapies in LPS-induced sepsis, and especially the use of oral leucine might be of great interest to the readers engaged in this field. We believe this study is important and provides solid evidence on the potential use of leucine in sepsis.

    1. eLife assessment

      This useful study presents a novel method to analyze the correlation between the degree of pigmentation, and the gene expression profile of human-induced pluripotent stem cell-derived Retinal Pigmented Epithelial (iPSC-RPE) cells at the single cell level, trying to establish if this parameter might be of use as a guide for transplantation. The presented evidence is incomplete: pigmentation was not an indicator of functionality or maturity and the data, although obtained from a pertinent approach, is limited to in vitro conditions; further, this approach is not complete since no attempts were made to graft iPSC-RPE.

    1. eLife assessment

      This useful study introduces a simple mechanical model of C. elegans locomotion that captures aspects of the worm's behavioral repertoire beyond forward crawling. While the kinetic model (ElegansBot) provides a useful compromise and starting point to help understand the mechanical components of C. elegans behavior, the claim that this work improves on extant mechanical models is incomplete. In addition, the results of the application of the model to previously unstudied behaviors are primarily qualitative and do not produce new predictions.

    1. eLife assessment

      This study presents a valuable finding on developing a state-of-the-art generative model of brain electrophysiological signals to explain temporal decoding matrices widely used in cognitive neuroscience. The evidence supporting the authors' claims is convincing. The results will be strengthened by providing more clear mappings between neurobiological mechanisms and signal generators in the model. The work will be of interest to cognitive neuroscientists using electrophysiological recordings.

    1. eLife assessment

      In this important paper, Blin and colleagues develop a high-throughput behavioral assay to test spontaneous swimming and olfactory preference in individual Mexican cavefish larvae. The authors present compelling evidence that the surface and cave morphs of the fish show different olfactory preferences and odor sensitivities and that individual fish show substantial variability in their spontaneous activity that is relevant for olfactory behaviour. The paper will be of interest to neurobiologists working on the evolution of behaviour, olfaction, and the individuality of behaviour.

    1. eLife assessment

      This study by Chiu and colleagues is a valuable contribution to the study of the circuitry of aggressive behaviours and of mechanisms that generate persistent behavioural states. The authors find that activation of two interconnected sets of neurons results in an increase in female aggression. The data ruling out recurrent connectivity between these clusters underlying this persistent state are convincing.

    1. eLife assessment

      This important study reports on a new method for the fabrication and the analysis of the transport through nuclear pore complexes mimic. Methods, data and analyses are convincing and show a clear correlation between the size of the nuclear pore complex mimic and its transport selectivity. This work will be of high interest to biologists and biophysicists working on the mechanosensitivity of nucleocytoplasmic transport.

    1. eLife assessment

      This valuable study analyzes a large cohort of Adolescent Idiopathic Scoliosis (AIS) patients, identifying an association with a variant in COL11A1 (Pro1335Leu). Experimental testing of this potentially pathogenic variant in vitro suggests a connection between Pax1, Col11a1, Mmp3, and estrogen signaling, thus providing solid support for the proposed link between hormonal and matrix components in the development of AIS.

    1. eLife assessment

      This useful study applies solid and previously validated methodology to identify archaically introgressed genes involved in high altitude adaptation. However, to test the robustness of the approach, this study would benefit from using at least one other method to detect adaptive introgression, and clarification on how the authors scored the networks in the signet analysis. With these parts strengthened, this paper would be of interest to population geneticists, anthropologists, and scientists interested in the genetic basis underlying high-altitude adaptation in Tibet.

    1. eLife assessment

      This valuable study reports on the genome evolution of a poorly studied fungal group. By combining long-read sequencing and various bioinformatics approaches, the authors show that the giant genome of Entomophthora muscae expanded due to extensive transposable element activity. The strength of evidence is largely solid, but some analyses are only partially supported due to different methodologies used to analyze the genomes that are being compared. This paper will be of relevance to fungal biologists as well as to evolutionary biologists interested in the study of genome size dynamics.

    1. eLife assessment

      The manuscript describes important findings supported by convincing data. The authors present persuasive genetic and biochemical evidence that supports the biological mechanism for optimal nodulation in soybean presented in this study. The results are of relevance to understanding the signaling pathway underpinning beneficial rhizobia symbiosis, while repressing the immune response. With the discussion part strengthened this paper would be of broad interest to plant biologists working on cell signaling and plant-microbe interactions.

    1. eLife assessment

      This manuscript investigates how chloroplasts are broken down during light-limiting conditions as plants reorganize their energy-producing organelles during carbon limitation. The authors provide convincing live-cell imaging data of plastids, documenting that buds form on the surface of chloroplasts and pinch away, then associate with the vacuole via a mechanism that depends on autophagy machinery, but not plastid division machinery. However, the absence of quantitative analyses makes the work incomplete at the current stage. The manuscript nevertheless provides important groundwork for other scientists studying the regulation and breakdown of energy-producing organelles, including chloroplasts and mitochondria.

    1. eLife assessment

      This study provides useful information by identifying the cell type (macrophages) in synovial tissues involved in the pathogenesis of post-traumatic osteoarthritis (OA) and clarifying distinct transcriptomic signatures that may be a good therapeutic target for OA. However, the analysis performed so far is incomplete, with a main weakness being the lack of data to confirm the authors' speculation about the underlying mechanisms.

    1. eLife assessment

      This important study presents a new way to selectively activate a cell signaling pathway in a specific cell type by designer ligands that link signaling co-receptors to a marker specific to the target cells. Convincing experimental results demonstrate that the agonist molecules activate Wnt signaling in target cells expressing the marker as intended. More broadly, this concept could be used to induce Wnt signaling or another pathway initiated by co-receptor association in a cell type-specific manner. In vitro results in this study could be further strengthened by assessing the biological consequences of Wnt activation in target cells.

    1. eLife assessment

      This important study reports the generation of genetic tools for manipulating several tissues at the same time in Drosophila. The authors provide convincing evidence that this allows the generation of LexA and QF2 driver lines, which will be of great utility for understanding inter-organ communication. Making the tools available through the Drosophila stock center and plasmid depository will ensure that they are easily accessed by many researchers.

    1. eLife assessment

      This study represents a valuable mechanistic contribution towards understanding how ribosomal RNA is processed during ribosome biogenesis. The biochemical evidence supporting the major conclusions is convincing. This work will be of interest to cell biologists and biochemists working on ribosome biogenesis.

    1. eLife assessment

      This study presents valuable findings on the potential of short-movie viewing fMRI protocol to explore the functional and topographical organization of the visual system in awake infants and toddlers. Although the data are compelling given the difficulty of studying this population, the evidence presented is incomplete and would be strengthened by additional analyses to support the authors' claims. This study will be of interest to cognitive neuroscientists and developmental psychologists, especially those interested in using fMRI to investigate brain organisation in pediatric and clinical populations with limited fMRI tolerance.

    1. eLife assessment

      This valuable study draws attention to the importance of a previously overlooked structural motif in kinase regulation. While the data presented are intriguing and mostly solid, further analysis and additional experiments will be needed in the future to support the authors' hypothesis. The work will be of interest to protein biochemists and enzymologists with an interest in kinases and allostery.

    1. eLife assessment

      The reviewers were generally enthusiastic about this study, noting that it reports new tools that could be valuable to the community. However, the results in follow-up experiments testing specific tools are often inconsistent with those in the literature, and some conclusions are overstated. More details are needed for both sections, the tool generation and the testing of the CNMa peptide. While the evidence for the tool development was solid, evidence demonstrating the validity of the tools was deemed incomplete.

    1. eLife assessment

      This important study combines disease-associated genetic variation with a massively parallel reporter assay and different cellular perturbations to identify context-specific genetic regulatory effects. The methods and analyses are solid and the proposed functional variants will be helpful for experimental and quantitative geneticists studying a wide range of complex traits.

    1. eLife assessment

      In this manuscript, the authors investigate whether the effects of the BCG vaccine on immunity to Mtb infection could be improved by inhibiting amidation of the peptidoglycan sidechains to allow for recognition by NOD-1. This is a very important area and an interesting new approach to improve vaccination for TB. The authors find that CRISPRi knockdown of murT-gatD causes rather dramatic cell wall defects, more accessible cell wall labeling, and results in attenuated growth in macrophages and mice. This forms a foundation for further study of whether an approach like that which is presented herein would improve vaccination responses in TB.

    1. eLife assessment

      In this study, deep learning methods are deployed in the context of a group hunting scenario wherein two predators pursue a single prey. Through deep learning, the two predators achieve higher predation success than occurs with single predators. Much of the evidence in this important study is solid, with implications for future work on the ethology and simulation of cooperative behaviors.

    1. eLife assessment

      This study provides a valuable investigation into whether phenotypic variance due to interactions between genetic variants can be measured using genome-wide association summary statistics. The authors present a method, i-LDSC, that uses statistics on the correlations between genotypes at different loci (linkage disequilibrium) to estimate the phenotypic variance explained by both additive genetic effects and pairwise interactions. While the authors present extensive simulations on the performance of their method and empirical results indicating the presence of epistasis (as they define epistasis) it is unclear how their method and results relate to the traditional definitions of additive and non-additive genetic effects, which are different from the authors' definitions.

    1. eLife assessment

      This study presents valuable findings regarding inter-individual variability in the neural and behavioral effects of ketamine. The methodological approach used to characterize this variability is compelling, but the evidence to support the specificity of the changes and their genetic correlates is incomplete. The study would benefit from a more thorough examination of the specificity of the pharmacological and genetic results.

    1. eLife assessment

      This study presents a useful deep learning-based inter-protein contact prediction method named PLMGraph-Inter which combines protein language models and geometric graphs. The evidence supporting the claims of the authors is solid, although it could have information leakage between training and test sets, and although more emphasis should be given to predictions starting from unbound monomer structures. The authors show that their approach may be useful in some cases where AlphaFold-Multimer performs poorly. This work will be of interest to researchers working on protein complex structure prediction, particularly when accurate experimental structures are available for one or both of the monomers in isolation.

    1. eLife assessment

      The bacterial neurotransmitter:sodium symporter homoglogue LeuT is an well-established model system for understanding the fundamental basis for how human monoamine transporters, such as the dopamine and serotonin, couple ions with neurotransmitter uptake. Here the authors provide convincing data to show that K+ binding on the intraceullular side catalyses the return step of the transport cycle in LeuT by binding to one of the two sodium sites. The mechansitic consequences of K+ binding could either facilitate LeuT re-setting and/or prevent the rebinding and possible efflux of Na+ and substrate.

    1. eLife assessment

      This paper reports the fundamental discovery of adrenergic modulation of spontaneous firing through the inhibition of the Na+ leak channel NALCN in cartwheel cells in the dorsal cochlear nucleus. This study provides unequivocal evidence that the activation of alpha-2 adrenergic or GABA-B receptors inhibit NALCN currents to reduce neuronal excitability. The evidence supporting the conclusions is exceptional, the electrophysiological data is high quality and the experimental design is rigorous.

    1. eLife assessment

      The authors pair single-cell sequencing technology with the LoopSeq synthetic long-read method to examine samples of hepatocellular carcinoma and benign liver, with the goal of identifying mutations and fusion transcripts specific to cancer cells. The authors present a valuable resource and the overall support for the major claims is solid.

    1. eLife assessment

      This important study explores infants' attention patterns in real-world settings using advanced protocols and cutting-edge methods. The presented evidence for the role of EEG theta power in infants' attention is currently incomplete. The study will be of interest to researchers working on the development and control of attention.

    1. eLife assessment

      In this important study, chromatin is simulated as a polymer at the scale of genes, and the 3D organization of chromatin is analyzed at nucleosome resolution. There is convincing evidence for the emergence of chromatin microdomains due to the action of transcription factors, based on the simulation incorporating well-known biophysical properties of DNA, of nucleosomes, of linker histones, and of the transcription factor pair Myc:Max, as well as considering how the 3D organization of chromatin results from bending and looping of DNA. The work greatly improves our understanding of how the joint action of transcription factors and chromatin features affects chromatin structure and accessibility, which is of interest to anyone studying gene regulation.

    1. eLife assessment

      This paper, offering insights into the mechanisms of neuronal cell type diversification, provides important findings that have theoretical or practical implications beyond a single subfield. The data are compelling and provide evidence that features methods, data and analyses that are more rigorous than the current state-of-the-art.

    1. eLife assessment

      This paper explores how Notch activity acts together with homeodomain transcription Bsh factors to establish distinct cell fates (L4 vs L5) in the visual system of Drosophila. The findings are important and have theoretical or practical implications beyond a single subfield. The methods, data, and analyses are compelling and support the claims with only minor weaknesses.

    1. eLife assessment

      This useful study presents a possible solution for a significant problem - that of draining vein sensitivity in functional MRI, which complicates the interpretability of laminar-fMRI results. The addition of a low diffusion-weighted gradient is presented to remove the draining vein signal and obtain functional responses with higher spatial fidelity. However, the strength of the evidence is inadequate, most tests appear to have been done only in a single subject. Significance thresholds in presented maps are very low and most cortical depth-dependent response profiles do not differ from baseline, even in the BOLD data shown as reference. Curiously, even BOLD group data fails to replicate the well-known pattern of draining towards the cortical surface.

    1. eLife assessment

      This important study combines psychophysics, fMRI, and TMS to reveal a causal role of FEF in generating an attention-induced ocular dominance shift, with potential relevance for clinical applications. The evidence supporting the claims of the authors is solid, but the theoretical and mechanistic interpretation of results and experimental approaches need to be strengthened. The work will be of broad interest to perceptual and cognitive neuroscience.

    1. eLife assessment

      This important study presents a detailed investigation of the early development of cardiac and respiratory interoceptive sensitivity in infants aged 3, 9, and 18 months. The evidence supporting the conclusions are solid and based on convincing statistical analyses, despite the limited sample size for the younger and older age groups. This study will be of significant interest to developmental psychologists and neuroscientists working on interoception and its influence on socio-cognitive development.

    1. eLife assessment

      This study presents a valuable framework and findings for our understanding of the brain as a fractal object, by observing the stability of its shape property within 11 primate species. Although the framework is well-detailed, the evidence presented is incomplete and would be strengthened by additional analyses to support the authors' claims, particularly on the effects of aging and on the interpretation of links between brain shape and the underlying anatomy. This study will be of interest to neuroscientists interested in brain morphology, and to physicists and mathematicians interested in modeling the shapes of complex objects.

    1. eLife assessment

      In the last 15 years, large-scale association studies (GWAS) have served to estimate the association between genome-wide common variants and a large number of disparate traits and diseases in humans. This valuable method provides a new way to find correlations between the genetic component of a phenotype of interest, and all this wealth of genetic information. This software adds as a new tool to investigate genetic correlation between traits, and to generate new mechanistic hypotheses and dissect the role of the observed associations in disease heterogeneity. The results of the application of their method are solid and generally agree with what others have seen using similar AD and UKB data.

    1. eLife assessment

      This study presents important findings on the different polymorphs of alpha-synuclein filaments that form at various pH's during in vitro assembly reactions with purified recombinant protein. Of particular note is the discovery of two new polymorphs (1M and 5A) that form in PBS buffer at pH 7. The strength of the evidence presented is solid, but the addition of replicate experiments with re-purified proteins at pH 5.8 and pH 7 would further strengthen the conclusions. The work will be of interest to biochemists and biophysicists working on protein aggregation and amyloids.

    1. eLife assessment

      This valuable manuscript demonstrates that the glycosyltransferase UGGT slows the degradation of endoplasmic reticulum (ER)-associated degradation substrates through a mechanism involving re-glucosylation of asparagine-linked glycans following release from the calnexin/calreticulin lectins. The evidence supporting this conclusion is solid using genetically-deficient cell models and biochemical methods to monitor the degradation of trafficking-incompetent ER-associated degradation substrates, although the manuscript could be improved through additional studies directed towards defining potential functional differences between UGGT1 and UGGT2 and additional insights into the impact of UGGT on the nature of substrate glycosylation within the ER. This work will be of specific interest to those interested in mechanistic aspects of ER protein quality control and protein secretion.

    1. eLife assessment

      The study provides valuable insights into OCD patients' acquisition of automaticity, skill learning, and the impact of intrinsic rewards on action sequence completion. The data provide incomplete evidence for the main claims as it is not clear that the participants' performance on the task meets the criteria for habitual behaviour.

    1. eLife assessment

      In this study, Ger and colleagues present a valuable new technique that uses recurrent neural networks to distinguish between model misspecification and behavioral stochasticity when interpreting cognitive-behavioral model fits. Evidence for the usefulness of this technique, which is currently based primarily on a relatively simple toy problem, is considered incomplete but could be improved via comparisons to existing approaches and/or applications to other problems. This technique addresses a long-standing problem that is likely to be of interest to researchers pushing the limits of cognitive computational modeling.

    1. eLife assessment

      This important study evaluates a model for multisensory correlation detection, focusing on the detection of correlated transients in visual and auditory stimuli. Overall, the experimental design is sound and the evidence is compelling. The synergy between the experimental and theoretical aspects of the paper is strong. The work will be of interest to neuroscientists and psychologists working in the domain of sensory processing and perception.

    1. eLife assessment

      This valuable study advances our understanding of the brain nuclei involved in rapid-eye movement (REM) sleep regulation. Using a combination of imaging, electrophysiology, and optogenetic tools, the study provides convincing evidence that inhibitory neurons in the preoptic area of the hypothalamus influence REM sleep. This work will be of interest to neurobiologists working on sleep and/or brain circuitry.

    1. eLife assessment

      This important study seeks to advance the current understanding of intergenerational olfactory changes associated with odor-induced fear conditioning in mice. Whilst the overall approach employed by the authors is appropriate and the evidence presented in support of claims is solid, there is general agreement that specific points - particularly the lack of effect in the F1 generation - deserve further attention.

    1. eLife assessment

      This useful study explores how archerfish adapt their shooting behavior to environmental changes, particularly airflow perturbations. It will be of interest to experts interested in mechanisms for motor learning. While the evidence for an internal model for adaptation is solid, evidence for adaptation to light refraction, as initially hypothesized, is inconclusive. As such, the evidence supporting an egocentric representation might be caused by alternative mechanisms to airflow perturbations.

    1. eLife assessment

      This valuable study uses a novel experimental design to elegantly demonstrate how we exploit stimulus structure to overcome working memory capacity limits. While the behavioural evidence is convincing, the neural evidence is incomplete, as it only provides partial support for the proposed information compression mechanism. This study will be of interest to cognitive neuroscientists studying structure learning and memory.

    1. eLife assessment

      This is an important theoretical study providing insight into how fluctuations in excitability can contribute to gradual changes in the mapping between population activity and stimulus, commonly referred to as representational drift. The authors provide convincing evidence that fluctuations can contribute to drift. Overall, this is a well-presented study that explores the question of how changes in intrinsic excitability can influence distinct memory representations.

    1. eLife assessment

      This study provides important findings based on convincing evidence demonstrating that females and males have different strategies to regulate energy consumption in the brain in the context of low energy intake. While food deprivation reduces energy consumption and visual processing performance in the visual cortex of males, the female cortex is unaffected, likely at the expense of other functions. This study is relevant for scientists interested in body metabolism and neuroscience.

      Zhang et al. deliver an important transcriptomic atlas of the human spinal cord, combining single-cell and spatial transcriptomics to unveil molecular insights. While convincingly overcoming Visium limitations using snRNA-seq, the manuscript is criticized for its largely observational approach and lack of quantitative analysis, especially in supporting claims about sex differences in motor neurons and DRG-spinal cord neuronal interactions.

    1. eLife assessment

      This study investigated the factors related to understudied genes in biomedical research. It showed that understudied genes are largely abandoned at the writing stage, and it identified a number of biological and experimental factors that influence which genes are selected for investigation. The study is a valuable contribution to this branch of meta-research, and while the evidence in support of the findings is solid, the interpretation and presentation of the results (especially the figures) needs to be improved.

    1. eLife assessment

      This study presents findings on the structure and dynamics of the Type I ABC importer and bacterial osmolarity regulator OpuA, addressing the question of whether the substrate binding domains physically interact in a salt-dependent manner. Based on a collective assessment of the single-molecule fluorescence resonance energy transfer and cryogenic electron microscopy data, the researchers convincingly conclude that the substrate domains directly interact. These findings are valuable and it will be interesting to see if future studies can provide further evidence of this direct interaction and define it in further detail.

    1. eLife assessment

      The authors propose that the asymmetric segregation of the NuRD complex in C. elegans is regulated in a V-ATPase-dependent manner, that this plays a crucial role in determining the differential expression of the apoptosis activator egl-1 and that it is therefore critical for the life/death fate decision in this species. The proposed model is interesting and the work could be important if proven correct. However, the current evidence is inadequate to support the major claims.

    1. eLife assessment

      The identification of existing and new agents for the treatment of T-cell leukemias is clearly significant to the field of cancer biology and experimental therapeutics. This manuscript identifies an important role of Cannabis based derivatives in the treatment of T-ALL in disease-relevant cell-based and in vivo models of the disease. The work has provided new mechanistic insights into how these drugs are working, with convincing evidence. However, further work to define the exact molecular target of these drugs and expanding the work beyond a limited number of cell lines would strengthen the conclusions and impact of this work.

    1. eLife assessment

      This study presents a valuable finding on how the GAP DLC1, a deactivator of the small GTPase RhoA, regulates RhoA activity globally as well as at Focal Adhesions. Using a new acute optogenetic system coupled to a RhoA activity biosensor, the authors present solid evidence that DLC1 amplifies local Rho activity at Focal Adhesions. Nevertheless, the proposed mechanism could be further supported by a deeper analysis of the data.

    1. eLife assessment

      This study presents valuable findings characterising the genomic features of E. coli isolated from neonatal meningitis from seven countries, and documents bacterial persistence and reinfection in two case studies. The genomic analyses are solid, although the inclusion of a larger number of isolates from more diverse geographies would have strengthened the generalisability of findings. The work will be of interest to people involved in the management of neonatal meningitis patients, and those studying E. coli epidemiology, diversity, and pathogenesis.

    1. eLife assessment

      This work reports a valuable finding on glucocorticoid signaling in male and female germ cells in mice, pointing out sexual dimorphism in transcriptomic responsiveness. The convincing evidence provided supports an inert GR signaling despite the presence of GR in the female germline and GR-mediated alternative splicing in response to dexamethasone treatment in the male germline. The work may interest basic researchers and physician-scientists working on reproduction and stress-related disease conditions.

      This solid study presents a useful dataset regarding chromatin remodeling by the BAF complex in the context of meiotic sex chromosome inactivation. Using knockouts of the BAF complex subunit ARID1A, there appears to be pachynema arrest and a failure to repress sex-linked genes, which is supported by an increase in chromatin accessibility, as assessed by ATAC-seq.
