The authors used ribosome profiling in conjunction with standard biochemical approaches to investigate the role of eIF2A in translation initiation in yeast under optimal growth conditions or stress. The convincing data demonstrate that eIF2A does not play a substantial role in translation initiation in yeast. These important findings challenge the current view that eIF2A substitutes for eIF2 under stress and are thus anticipated to spur future investigation on the role(s) of eIF2A. Considering the broad scope of cellular functions attributed to eIF2A, this study should be of interest to a wide spectrum of biomedical researchers ranging from those studying fundamental mechanisms of translation regulation to virologists and cancer biologists.

This valuable study employs a diverse array of techniques encompassing cell biological manipulations, biophysical measurements, and mouse models to elucidate the impact of target cell stiffness on CD8+ cytotoxic T cell activation, with a particular focus on the actin nucleator protein WASP. The finding that WASP is essential for the stiffness-dependent phosphorylation of ZAP70 in CD8 T cells is convincing. However, the data regarding the role of WASP in mechanosensing within CD8 T cell-mediated anti-tumor immunity is incomplete and would benefit from a more rigorous study design. This work would be of interest to cell biologists and investigators studying mechanosensing within the immune system.

Perampalam and colleagues provide solid evidence that Netrin signaling drives survival of non-proliferating ovarian cancer cells and their dissemination. These valuable findings were thought to provide unique insights into the molecular underpinnings of ovarian cancer spread and thus to be of significant interest to cancer biologists. However, the incomplete evidence supporting the role of the described Netrin-dependent mechanism in cancer dormancy was found to be a major shortcoming of the study.

eLife assessment

This manuscript addresses an important question, that in countries endemic for P vivax the need to administer a primaquine (PQ) course adequate to prevent relapse in G6PD deficient persons poses a real dilemma. On one hand PQ will cause haemolysis; on the other hand, without PQ the chance of relapse is very high. As a result, out of fear of severe haemolysis, PQ has been under-used. This manuscript is convincing that regimen (1) can be used successfully to deliver within 3 weeks, under hospital conditions, the dose of PQ required to prevent P vivax relapse.

eLife assessment

This useful study describes a single set of label-chase mass spectrometry experiments to confirm the molecular function of YafK as a peptidoglycan hydrolase, and to describe the timing of its attachment to the peptidoglycan. Confirmation of the molecular function of YafK will be helpful in further studies to examine the function and regulation of the outer membrane-peptidoglycan link in bacteria. The evidence supporting the molecular function of YafK and that lpp molecules are shuffled on and off the peptidoglycan is solid, however, data supporting conclusions relating to the locations of lpp-peptidoglycan attachment are incomplete. The work will be of interest to microbiologists studying the bacterial cell wall.

eLife assessment

This is an important study that investigates the role of commensal microbes and molecules in the antigen presentation pathway affecting the development and phenotype of an unusual population of T lymphocytes. The authors provide compelling evidence to identify a population of unconventional T cells that exist in the small intestinal epithelium, which appear to depend on commensal microbes, and show that a single commensal microbe (that encodes an antigen capable of weakly stimulating these cells) is sufficient to maintain this T cell population.

eLife assessment

Sulphur atoms derived from cysteine are thought to play significant roles in maintaining redox homeostasis in Mycobacterium tuberculosis, which encounters stresses associated with immune cell interactions. In this valuable manuscript, the authors provide solid evidence that the genes encoding cysteine biosynthetic enzymes (cysM and cysK2) are required to maintain full viability of M. tuberculosis under in vitro stress conditions, macrophage infections, and within the lung tissues of mice. The manuscript presents transcriptomic and metabolomic evidence to support the hypothesis that CysM and CysK2 play distinct roles in maintaining cysteine-derived metabolite pools under stress conditions. The work will be of interest to microbiologists in general.

This valuable work develops a new approach to measure imaginal disc growth in Drosophila. With this approach, the roles of two protocadherins (Fat and Dachsous), in late larval development is explored, and there is novel data on the scaling of their protein gradients. The evidence supporting the authors' findings overall are solid, though the genetic analysis of Fat and Dachsous function is incomplete and would benefit from further experiments.

This important work provides a detailed analysis of the population dynamics of an important human bacterial pathogen, Neisseria gonorrhoeae, using a large global collection of genomes with geographic, temporal, and demographic metadata. A unique facet of this work is the focus on both importation and exportation of N. gonorrhoeae; whilst quantifying importation is important to national public health efforts, quantifying exportation is relevant on an international level. However, the evidence supporting the conclusions is incomplete, due to potential inaccuracies in the method used for phylogenetic analysis, which forms the basis of this work. With the phylogenetic analysis strengthened, this paper would be of interest to epidemiologists and public health officials working on N. gonorrhoeae epidemiology and interventions.

This is an important report that has implications for both the brain stimulation field and beyond. The strength of evidence provided is quite convincing. The major strength of this work is the recognize the importance of participant expectation in brain stimulation studies.

eLife assessment

This study presents a useful method for the extraction of behaviour-related activity from neural population recordings based on a specific deep learning architecture - a variational autoencoder. However, the evidence supporting the scientific claims resulting from the application of this method is incomplete as the results may stem, in part, from its properties. The authors should: (1) improve how they benchmark their method, by comparing against additional relevant techniques, and (2) reframe their results considering what observations may be a byproduct of their method, and which do constitute new scientific observations.

eLife assessment

In this potentially useful study, the authors use deep learning models to provide solid evidence that epithelial wounding triggers bursts of cell division at a characteristic distance away from the wound.

This is a fundamental resource of snRNA-seq and and chromatin accessibility data from human aortic endothelial cells (ECs), treated with relevant perturbations such as IL1b, TGFB2, or si-EGR. The authors show that ECs can be categorized by distinct subpopulations of differing plasticity. The support for the existence of these subpopulations is compelling, supported also by three publicly available scRNA-seq datasets, and differential enrichment of coronary artery disease associated SNPs in open chromatin in these subpopulations. Inter alia, clarifications of controls and variability among EC responses would strengthen the interpretations of the study.

eLife assessment

This work provides a valuable characterization of the chaotic dynamics of high-dimensional spiking networks in the presence of internally generated oscillations due to synaptic delays or externally generated oscillations due to external input. The authors provide convincing analytical and numerical calculations to support their claims, however, the paper suffers from heavy mathematical jargon that reduces its impact. The paper could be revised to provide interpretations of the results so that it can be accessible to a broader neuroscience audience. In its current form, findings will be of interest mostly to researchers working at the interface between theoretical neuroscience, applied mathematics, and physics.

eLife assessment

This important study advances our understanding of how past and future information is jointly considered in visual working memory by studying gaze biases in a memory task that dissociates the locations during encoding and memory tests. The evidence supporting the conclusions is convincing, with state-of-the-art gaze analyses that build on a recent series of experiments introduced by the authors. This work, with further improvements incorporating the existing literature, will be of broad interest to vision scientists interested in the interplay of vision, eye movements, and memory.

eLife assessment

This is an important study that extends our understanding of how the medial prefrontal cortex regulates goal-directed action during threat. The authors provide convincing evidence that prefrontal cortex parvalbumin neurons suppress conditional freezing responses, permitting the initiation of active controlling responses over shock onset (termed 'avoidance'); also, this cell-type function does not generalize to appetitive situations or general locomotion. These findings are expected to be of great benefit to multiple neuroscience subfields interested in the mechanisms of adaptive behavior.

eLife assessment

The aim of this valuable study is to uncover developmental roles of the neuropeptide prothoracicotropic hormone (PTTH) and ecdysone, which later regulate female receptivity of Drosophila melanogaster. The work combines spatially and temporally restricted genetic manipulation with behavior quantification to explore these molecular pathways and the neuronal substrates participating in the control of female sexual receptivity. At present, the implication of both signaling pathways in this process is convincing but the strength of the evidence is incomplete to support the main claim that PTTH pathway controls female sexual receptivity through the function of ecdysone in pC1 neurons.

eLife assessment

This important and elegant study makes a significant step towards harmonisation of two perspectives on synaptic plasticity in the brain: Bayesian inference and energy efficiency. Through a combination of analytical derivations and numerical simulations, the authors make a compelling case that the two perspectives, which on the surface seem very different, are in fact closely related. In addition, they provide moderate experimental evidence that corroborates predictions of their synaptic plasticity models.

eLife assessment

Winter months with short days are commonly associated with seasonal depression and hypersomnolence; the mechanisms behind this hypersomnolence however remain unclear. Chen and colleagues identify a genetic basis for this phenomenon in the fly Drosophila - mutations in the circadian photoreceptor cryptochrome resulted in increased sleep under short photoperiods. These findings are potentially valuable insights into the genetic mechanisms regulating sleep under short days. The data supporting the neurobiological basis of these effects is however incomplete.

eLife assessment

This study reports valuable findings that corticostriatal projections (specifically, from M1 and MCC ) target direct and indirect pathway striatal projection neurons in partially segregated ways. Moreover, this partial segregation is biased, implying that specific engagement of the direct pathway may be achieved through the selective activation of unique cortical neurons. The evidence for this conclusion is solid, though the key experiments (rabies tracing controls, etc.) are incomplete. Otherwise, the experiments are rigorously designed, and the results are solid. This work will be of interest to those interested in brain anatomy and/or circuitry, cortical and/or basal ganglia function, locomotor activity, reinforcement learning, or diseases related to these.

eLife assessment

This MEG study reports valuable new findings regarding the nature of memory reactivation during cued recall. It replicates previous work showing that such reactivation can be sequential or clustered, with sequential reactivation being more prevalent in low performers. It adds solid evidence, even though based on limited data, that item strengths during clustered reactivation vary with item distance in the learned graph structure. The study will be of interest to human and rodent neuroscientists working on memory replay.

eLife assessment

This is a valuable computational study that applies the machine learning method of bilinear modeling to the problem of relating gene expression to connectivity. Specifically, the author attempts to use transcriptomic data from mouse retinal neurons to predict their known connectivity. The results are promising, although the reviewers felt that demonstration of the general applicability of the approach required testing it against a second data set. Hence the present results were felt to provide borderline incomplete support for a key premise of the paper.

eLife assessment

In this paper, the authors introduce fundamental work on mathematical methods for inferring evolutionary parameters of interest from RNA data in healthy tissue and during hematopoiesis. By combining single cell and bulk sequencing analyses, the authors use a stochastic process to inform different aspects of genetic heterogeneity; the strength of evidence in support of the authors' claim is exceptional. The work will be of broad interest to cell biologists and theoretical biologists.

eLife assessment

This review examines seasonal dormancy in various species, including hibernating mammals (excluding bats and bears) and ectotherms. It tests hypotheses on dormancy timing, considering energetic constraints and life history as alternative drivers. While the review is valuable, ecological differences between males and females can drive differences in energy balance, hence the idea that sex differences in dormancy timing are associated with non-energy constraints. Evidence supporting a life-history hypothesis is therefore somewhat incomplete. Nonetheless, examining these alternative hypotheses is of interest to evolutionary biologists, and including a diverse range of species, population-level traits, and some ecological context would enhance the value of the review.

In doing so, the authors elucidate the diversification of fossil proboscideans and their likely evolutionary responses to late Cenozoic global climatic changes.

eLife assessment

This valuable manuscript reports on the relationship between GTP hydrolysis parameters and kinase activity of LRRK2, which is associated with Parkinson's disease. The authors provide a detailed accounting of the catalytic efficiency of the ROC GTPase domain of pathogenic variants of LRRK2, in comparison with the wild-type enzyme. The authors propose that phosphorylation of T1343 inhibits kinase activity and influences monomer-dimer transitions, but the experimental evidence is currently incomplete.

eLife assessment

This is a theoretical analysis that gives compelling evidence that length control of bundles of actin filaments undergoing assembly and disassembly emerges even in the absence of a length control mechanism at the individual filament level. Furthermore, the length distribution should exhibit a variance that grows quadratically with the average bundle length. The experimental data are compatible with these fundamental theoretical findings, but further investigations are necessary to make the work conclusive concerning the validity of the inferences for filamentous actin structures in cells.

eLife assessment

The authors present 16 new well-preserved specimens from the early Cambrian Chengjiang biota. These specimens potentially represent a new taxon which could be useful in sorting out the problematic topology of artiopodan arthropods - a topic of interest to specialists in Cambrian arthropods. Because the anatomic features in the new specimens were neither properly revealed nor correctly interpreted, the evidence for several conclusions is inadequate.

This valuable study presents presents solid evidence that an anti-CTLA-4 antibody drug conjugate transiently depletes circulating B cells in a mouse model, showing how dysregulation of the T cell immune system can impact B cell homeostasis. The work will be of broad interest to immunologists and medical biologists, but a major limitation is that the mechanism of B-cell reduction remains unclear, as evidence of killing of B-cells by T-cells is not presented.

eLife assessment

This study presents valuable information that an anti-CTLA-4 antibody drug conjugate transiently depletes circulating B-lymphocytes in a mouse model. It shows how dysregulation of the T cell immune system can impact B cell homeostasis. The work will be of broad interest to immunologists and medical biologists, but the strength of evidence is incomplete at this time mainly because they only analyzed circulating B cells.

eLife assessment

This important study offers new and convincing support for the idea that about a third of mouse liver DNAse hypersensitivity sites (DHS) showing male-biased chromatin opening are sex-biased because of the male-specific cyclic action of growth hormone pulses to alter chromatin accessibility, as compared to the relative ineffectiveness of the more static pattern of growth hormone secretion in females. Supporting evidence is found in the impact of hypophysectomy and growth hormone treatment on chromatin accessibility, and the binding of specific transcription factors and epigenetic marks at STAT5-sensitive sites. This work uncovers mechanisms underlying sex differences in liver function and will be of broad interest to endocrinologists and hepatologists.

eLife assessment

This study defines the roles for two different missense mutations observed in patients in the Trabid/ZRANB1 gene associated in children with a range of congenital disorders including reduced brain size. The study is important because the findings have theoretical or practical implications beyond a single subfield, as the study of DUB and cytoskeletal alterations have implications for neurodevelopment broadly. The methods are convincing as they utilize appropriate and validated methodology in line with current state-of-the-art by incorporating knock-in mice of the patient mutations. Many of the reviewer comments were focused on potential next experiments, rather than on evaluation of the data at hand, and the authors have considered these as future studies. The work as presented suggests critical roles for Trabid in the STRIPAK complex mediating APC deubiquitylation.

eLife assessment

This work presents important findings regarding the use of soil environmental DNA for non-invasive monitoring of the endangered kākāpō parrot population in New Zealand.

eLife assessment

This valuable data study presents convincing data that expression of the C. elegans transcription factor NHR-67 is sufficient to drive an invasive fate, and that the alternative proliferative fate is associated with NHR-67 transcriptional down-regulation. While the observation that NHR-67 forms punctae associated with transcriptional repressors in non-invasive cells is intriguing, the work does not yet established a clear link between the formation and dissolution of NHR-67 condensates with the activation of downstream genes that NHR-67 is actively repressing. The work will be of interest to developmental biologists studying transcriptional control of cell fate specification in animals, especially once issues around the functional significance of the NHR-67 contiaining punctae are resolved.

This fundamental work proposes a novel mechanism for memory consolidation where short-term memory provides a gating signal for memories to be consolidated into long-term storage. The work combines extensive analytical and numerical work applied to three different scenarios and provides a convincing analysis of the benefits of the proposed model, although some of the analyses are limited to the type of memory consolidation the authors consider (and don't consider), which limits the impact. The work could be revised to include a more thorough comparison to existing models of memory consolidation and a discussion of its limitations, and the revision could also streamline the technical terminology. The work will be of interest to neuroscientists and many other researchers interested in the mechanistic underpinnings of memory.

eLife assessment

This is a potentially important study that integrates QM/MM free energy simulations and experimental kinetic analyses to probe the nature of phosphoryl transfer transition state in adenylate kinase. The idea that the transition state ensemble encompasses conformations with substantially different structural features (including the breaking/forming bonds) is interesting and potentially applicable to many other enzyme systems. In the current form, however, the study is considered incomplete since the connection between the putative transition state ensemble from the computations and key experimental observables, such as the activation entropy, is not well established.

This manuscript describes structures of HER4 homo- and HER4/HER2 hetero-dimer complexes using single particle cryo-EM. This important work describes convincingly new structural details of these complexes that expand our understanding of their function.

eLife assessment

The work is a useful contribution towards understanding the role of archaeal and plant D-aminoacyl-tRNA deacylase 2 (DTD2) in deacylation and detoxification of D-Tyr-tRNATyr modified by various aldehydes produced as metabolic byproducts in plants. It integrates convincing results from both in vitro and in vivo experiments to address the long-standing puzzle of why plants outperform bacteria in handling reactive aldehydes and suggests a new strategy for stress-tolerant crops. The impact of the paper is limited by the fact that only one modified D-aminoacyl tRNA was examined, in lack of evidence that plant eEF1A mimics EF-Tu in protecting L-aminoacyl tRNAs from modification, and in failure to measure accumulation of toxic D-aminoacyl tRNAs or impairment of translation in plant cells lacking DTD2.

eLife assessment

The work by Johnson and co-workers has identified an important role of 2-Hydroxybutyrate in skeletal muscle oxidative capacity in the early stages of exercise. Mechanistically, they show convincing data to support a role of 2-Hydroxybutyrate in the regulation of BCAA metabolism via SIRT4, ADP-Ribosylation, and CEBP. However, whether this is the sole mechanism and if these translate to longer exercise training regimes requires future experiments.

This important paper exploits new cryo-EM tomography tools to examine the state of chromatin in situ. The experimental work is meticulously performed, with a vast amount of data collected, with convincing interpretation of possible nucleosomal structures in yeast. The majority of these nucleosomes appear not to possess stable octameric configurations. Although it cannot be excluded that there could be an unknown bias in class detection, we agree that the authors have gone as far as is possible, given constraints in current technology and analysis, to support their model. Despite the provocative nature of this report, it is our hope that such work will spark debate, and further the development of exciting new tools that can interrogate the dynamic nature of the nucleosome, and its associated functions in situ.

This study presents valuable observations on the role of creatine (Cr) in the context of synaptic transmission. Overall, the data are solid in support of the conclusion that Cr is present in synaptic vesicles, although the evidence for Cr release and Cr-dependent modulation of neuronal function was considered incomplete. The work will be of general interest to the field of neuroscience.

This is a valuable comparative study of local adaptation using gene-by-environment and gene-by-phenotype correlations. The analyses seemed still incomplete, as the biological take-home messages were obscured by the statistical approaches used, and it remains unclear how to best interpret the level of genome-wide convergence and in inversions. The repeatability of local adaptation across species, and the role of inversions in local adaptation, are questions of considerable empirical interest.

This is a valuable information-theoretic re-analysis of human intracranial recordings during reward and punishment learning. It provides solid evidence that reward and punishment learning is represented in overlapping regions of the brain while relying on specific inter-regional interactions. However, there are weaknesses in the analysis approach that raise concerns about the consistency of the effects across participants and the interpretation of the findings. This preprint will be interesting to researchers in systems and cognitive neuroscience.

This fundamental study addresses the earliest events that enable plant roots to reorient growth in response to gravity. Compelling molecular and cell biological data establish that plasma membrane localization of the LAZY or NEGATIVE GRAVITROPIC RESPONSE OF ROOTS (NGR) protein family is required for rapid and polar redirection of D6 protein kinase, an activator of the PIN3 auxin transporter. This work complements recent publications on the NGR family in gravity sensing (Chen et al., PMID: 37741279 and Nishimura et al., PMID: 37561884). Collectively these papers advance our understanding of rapid plant gravity sensing and response.

This manuscript describes useful information on the interactions of the BRAF N-terminal regulatory regions (CRD, RBD and BSR) with the C-terminal kinase domain and with the upstream regulators HRAS and KRAS. The authors provide solid evidence that the BRAF BSR domain may negatively regulate RAS binding and propose that the presence of the BSR domain in BRAF provides an additional layer of autoinhibitory constraints. The data will be of interest for researchers in the RAS/RAF and general kinase regulation fields.

eLife assessment

This important study examined whether the BMP signaling pathway has a role in H3.3K27M DMG tumors, regardless of the presence of ACRVR1 activating mutations. The authors show compelling evidence that BMP2/7 synergizes with H3.3K27M to induce a transcriptomic rewiring associated with a quiescent but invasive cell state. Although this work could be further enhanced by the inclusion of additional models as well as further consideration of elements, such as the location of the tumor, in the datasets used, overall this work suggests that BMP2/7 could be considered as a target for future therapies in this deadly cancer.

This study presents a useful finding on the role of GABRD and its downstream target CDK1 in the progression of breast cancer. The evidence supporting the claims of the authors is somewhat incomplete and the elaboration of the mechanistic details on GABARD/CDK1 regulation would have strengthened the study. The work will be of interest to clinicians and biologists working on breast cancer.

This important study substantially advances our understanding of pediatric Crohn's disease, mapping the cellular make-up of this disease and how patients respond to treatment. The evidence supporting the conclusions is compelling, with thorough bioinformatic analyses, underpinned by rigorous methodology and data integration. The work will be of broad interest to pediatric clinicians, immunologists and bioinformaticians.

The authors analyzed the causative association between circulating immune cells and periodontitis, and reported three risk immune cells related to periodontitis. The significance of the findings is fundamental, which substantially advances our understanding of periodontitis. The strength of evidence is convincing.

This manuscript reports important in vitro biochemical and in planta experiments to study the receptor activation mechanism of plant membrane receptor kinase complexes with non-catalytic intracellular kinase domains. Several lines of evidence convincingly show that one such putative pseudokinase, the immune receptor EFR achieves an active conformation following phosphorylation by a co-receptor kinase, and then in turn activates the co-receptor kinase allosterically to enable it to phosphorylate down-stream signaling components. This manuscript will be of interest to scientists focusing on cell signalling and allosteric regulation.

eLife assessment

This useful manuscript reports mechanisms behind the increase in fecundity in response to sub-lethal doses of pesticides in the crop pest, the brown plant hopper. The authors hypothesize that the pesticide works by inducing the JH titer, which through the JH signaling pathway induces egg development. Evidence for this is, however, inadequate.

This valuable manuscript provides solid methodologies for utilizing SMALP nanodisks for oligomer characterization. The authors present a platform for capturing and studying native membrane protein oligomerization and subsequent cryoEM analysis. The specific application of the method to WbaP, a membrane-bound phosphoglycosyl transferase, adds to our understanding of glycoconjugate production in bacteria. This manuscript would be of interest to those focusing on native membrane protein studies and antimicrobial resistance.

eLife assessment

This important paper addresses the challenging problem of dating the origin of several groups of marine microorganisms. However, while much of the analyses are solid, the lack of robustness analysis in molecular dating component such as using alternative time calibrations, clock models, and input gene sets makes the study incomplete. Despite some concerns, this work is a commendable attempt at an extremely difficult problem and will be of broad interest to microbiologists, geologists, and evolutionary biologists.

eLife assessment

This important paper addresses the challenging problem of dating the origin of several groups of marine microorganisms. The analyses are solid, with various test of clock models and time calibrations used, however given the uncertainty of many of the dates used to anchor ancient geological events, further studies are needed to support or refute the hypotheses put forth in this paper. Despite some methodological concerns, this work is a commendable attempt at an extremely difficult problem and will be of broad interest to microbiologists, geologists, and evolutionary biologists.

eLife assessment

This paper identifies a subset of neurons within adult mouse myenteric ganglia that are not labeled via canonical neural-crest labeling, and argues, based on extensive lineage tracing, imaging and genomic data that these neurons are derived from mesoderm. There is convincing evidence for the existence of an unusual cell type in the gut that expresses neuronal markers, but which is derived from cells expressing markers of the mesoderm rather than the expected neural crest, which is an intriguing and important observation. While the data do not definitively establish the molecular taxonomy of this lineage, there is sufficient evidence to support the provocative and paradigm-shifting hypothesis of the non-ectodermal origin for enteric neurons to warrant further deeper investigation.

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 solid 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.

eLife assessment

This important study sheds light on the role of sphingolipids on the maturation of Parkinson's disease-associated Synphilin-1 inclusion bodies (SY1 IBs) on the mitochondrial surface in a yeast model using Synthetic Genetic Array (SGA) and state-of-the-art imaging techniques. The authors provide solid evidence that downregulating the sphingolipid biosynthesis pathway leads to defective maturation and enhanced toxicity of SY1 IBs in both yeast and mammalian cells. However, these data neither explain the role of mitochondrial surface sphingolipids in SY1 IB maturation (the cellular site of maturation of smaller toxic aggregates to bigger less toxic IBs), nor the requirement of mitochondrial activity in IB maturation.

eLife assessment

This study presents a valuable finding on the cell composition in mouse spleen depleted for the CD47 receptor and its signaling ligand Thrombospondin in hematopoietic differentiation. The supporting evidence is convincing with analytical improvements on the individual contributions of the signaling components and with functional studies. This work has implications for the role of CD47/Thsp in extramedullary erythropoiesis in mouse spleen and will be of interest to researchers in cell signaling, transfusion medicine, and cell therapy.

eLife assessment

This valuable work deals with mathematical modeling of centrosome maturation, building on the insight that autocatalytic assembly of the centrosome leads to size inequality. To remedy this, the authors propose a catalytic growth model with a shared enzyme pool that is able to reproduce various experimental results such as centrosome size scaling with cell size and centrosome growth curves in C. elegans. While finding the work of interest, the strength of the evidence presented in favor of the model is incomplete.

eLife assessment

These important findings will be of interest for the study of dystroglycanopathies and in the general area of axon migration and synapse formation. This work provides convincing conclusions about how a range of dystroglycan mutations alter CCK interneuron axonal targeting and synaptic connectivity in the forebrain, and seizure susceptibility.

eLife assessment

This study provides a valuable finding on the mechanistic connections between epithelial-mesenchymal transition (EMT) and lipid metabolism. The authors identified the ZEB2/ACSL4 axis as a newly discovered metastatic metabolic pathway that promotes both lipogenesis and fatty acid oxidation. The evidence supporting the claims of the authors is solid. The work will be of interest to medical biologists working on cancer.

This paper reports important findings on a potent activator of the YAP pathway, demonstrating its mechanism through alternative splicing changes. The authors provide convincing evidence to support their claims. This research is of interest to biologists studying alternative splicing or the Hippo pathway, with significant implications for medical research.

eLife assessment

This valuable study advances our understanding of the evolution of protein complexes and their functions. Through convincing experimental and computational methodologies, the authors show that the specialization of protein function following gene duplication can be reversible. The work will be of interest to investigators working in biochemical evolution and those working on heat shock proteins.

eLife assessment

This valuable paper characterizes a murine model for congenital cystic airway abnormalities (CPAM). In contrast to previous assumptions that only epithelial cells are involved in the formation of pulmonary cysts, the authors provide compelling new evidence that defective BMP signaling in lung mesenchymal cells can disrupt airway development. Knowing that proper BMP signaling in mesenchymal cells is required for normal cyst-free lungs could potentially pave the way to understanding and preventing CPAM in infants at risk for this common disorder, which can be fatal if untreated. The relevance of the murine model could be enhanced by providing further histological details in comparison with human cysts, as well as interrogation of datasets such as GWAS whether genetic changes in human cysts are related to abnormal BMP signaling.

eLife assessment

This valuable study identifies an uncharacterized yeast gene regulating chronological lifespan in a mitochondrial-dependent pathway. The approach to identify and characterise this new gene is compelling, but the evidence is incomplete in supporting the major conclusions. With a stronger focus on the relevance of replicative in addition to chronological lifespan, and stronger data linking to mitochondrial function, this paper would be interesting to the yeast biologists working in metabolism and aging.

eLife assessment

This is a useful contribution to our understanding of how different cell stressors (ethanol or heat-shock) might elicit unique responses at the genomic and topographical level under the regulation of yeast transcription factor Hsf1, and of the temporal coupling (or lack thereof) between Hsf1 aggregation and long-range communication among co-regulated heat-shock loci versus chromatin remodeling and transcriptional activation. A particular strength is the combination of genomic and imaging-based experimental approaches applied to genetically engineered in vivo systems. While much of the data is convincing, the work is incomplete in not providing strong evidence supporting (i) a similar rate and extent of proteotoxic stress under the two chosen stress conditions, (ii) relatively greater bulk chromatin compaction elicited by ethanol, (iii) reproducible levels of interactions between chromosomal loci, and (iv) phase-separated condensates versus other types of Hsf1 clusters.

eLife assessment

This important work shows compelling evidence that Chandelier cells in the visual cortex receive inputs most prominently from local layer 5 pyramidal neurons, only mildly inhibit L2/3 pyramidal neurons, and respond massively to visuomotor mismatch. It also indicates that visual experience in the virtual tunnel activates a plasticity mechanism in Chandelier cells which could be due to the particular visuo-motor coupling experienced in this setting, although a specific control is lacking for this conclusion. This study will be of interest to neuroscientists involved in cortical circuits, visual processing, and predictive coding research.

This study reports useful information on the limits of the organotypic culture of neonatal mouse testes, which has been regarded as an experimental strategy that can be extended to humans in the clinical setting for the conservation and subsequent re-use of testicular tissue. The evidence that the culture of testicular fragments of 6.5-day-old mouse testes does not allow optimal differentiation of steroidogenic cells is compelling and should enable further optimizations in the future.

eLife assessment

This valuable study focuses on the role of the Gr28 family of insect chemoreceptors. Using the Drosophila larva, the authors show that taste neurons expressing different members of this family of bitter taste receptors trigger opposite behavior – attraction and repulsion. They establish the minimal bitter taste receptor subunit composition needed in these neurons to mediate the repulsion of bitter tastants. The evidence presented is convincing, using well-validated and controlled tools and experiments.

eLife assessment

This important study presents findings regarding the role of Juvenile Hormone in development and cell differentiation in the ametabolous insect Thermobia domestica, providing an in-depth analysis of JH's roles in a member of this basally branching group. The evidence supporting the claims of the authors is convincing, drawing on a broad range of approaches and variety of experimental techniques. While the interpretation of this work in the wider context regarding its relevance for the evolution of metamorphosis is in some places overly speculative, the work will be of interest to evolutionary developmental biologists studying hormonal control of development and to entomologists studying the evolution of metamorphosis.

eLife assessment

This potentially important paper compares cross-species cortical folding patterns in human and non-human primates, showing that most gyral peaks shared across species are in lower-order cortical regions. The supporting evidence is currently incomplete, requiring the addition of multiple comparison corrections and further clarification and elaboration upon the statistical procedures used.

eLife assessment

This valuable study has practical and possibly theoretical implications for rhythm perception and production by showing individual differences in frequency preferences, and a deterioration in frequency adaptation with age. As it stands, the evidence for the main claims regarding the entrainment of internal oscillators is incomplete and requires further consideration. Regardless, the findings may inform existing models of rhythm perception and production, and the effects of age may have clinical implications.

eLife assessment

These important findings stand out from other similar studies via solid demonstration of behavioural and neural relationships between two helping tasks - one focusing more on social perception, one more on its influence on social behaviour - that were performed more than 300 days apart. The claims however would be enhanced with a larger sample size and greater consideration of the fact that merit and need are signalled via quite different cues - such that differences between them may have multiple origins.

eLife assessment

This work describes new validated conditional double KO (cDKO) mice for LRRK1 and LRRK2 that will be useful for the field, given that LRRK2 is widely expressed in the brain and periphery, and many divergent phenotypes have been attributed previously to LRRK2 expression. The manuscript presents solid data demonstrating that it is the loss of LRRK1 and LRRK2 expression within the SNpc DA cells that is not well tolerated, as it was previously unclear from past work whether neurodegeneration in the LRRK double Knock Out (DKO) was cell autonomous or the result of loss of LRRK1/LRRK2 expression in other types of cells. Future studies may pursue the biochemical mechanisms underlying the reason for the apoptotic cells noted in this study, as here, the LRRK1/LRRK2 KO mice did not replicate the dramatic increase in the number of autophagic vacuoles previously noted in germline global LRRK1/LRRK2 KO mice.

eLife assessment

This study provides useful information on the function of a ciliary and flagellar-associated protein, CFAP52, in the assembly of sperm head-tail connecting apparatus (HTCA) and tail formation in humans and mice. The significance is to identify CFAP52 as a genetic factor for asthenoteratozoospermia with a mixed acephalic spermatozoa syndrome (ASS) and multiple morphological abnormalities of the sperm flagella (MMAF) phenotype. The strength of the study is that the experimental evidence using CFAP52 loss-of-function in mice is solid to support that CFAP52 is essential for sperm motility and male fertility by contributing to HTCA and 9+2 axoneme, corroborating the sperm phenotypes of human patients with compound heterozygous mutations in CFAP52.

This study reports an important physiological function of a conserved meiosis factor in spermatogenesis in mice. The genetic and cell biological evidence supporting the conclusion is convincing. This work will be of broad interest to cell biologists, geneticists, and reproductive biologists.

eLife assessment

This study provides useful datasets on gene expression and chromatin accessibility profiles in spermatogonial cells at different postnatal ages in mice. Overall, the technical aspects of the sequencing analyses and computational/bioinformatics are solid. However, there are concerns with the identity of the isolated cells and the lack of acknowledgment for previous studies that have also performed ATAC-sequencing on spermatogonia of mouse and human testes. The limitations call into question the validity of the interpretations and reduce the potential merit of the findings.

eLife assessment

This study provides a valuable survey of SMAD1/5 direct transcriptional events at the time of uterine receptivity to pregnancy in the mouse. The evidence supporting the authors' claims is solid, although functional validation, a more thorough genome-wide bioinformatic analysis, and better provision of methodological details would strengthen the study. The work will be of interest to reproductive biologists.

eLife assessment

This study presents valuable insights into the evolution of the gasdermin family, making a strong case that a GSDMA-like gasdermin was already present in early land vertebrates and was activated by caspase-1 cleavage. 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 presented 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.

eLife assessment

Using extensive atomistic molecular dynamics simulations, the authors analyzed the TCR/pMHC interface with different peptide sequences and protein constructs. The results provide important insights into the catch-bond phenomenon in the context of T-cell activation. In particular, the analysis points to convincing evidence that supports the role of force in further discriminating different peptides during the activation process beyond structural considerations.

This study presents a valuable inventory of immune responses to the BTN162b2 mRNA COVID-19 vaccination in 20 hemodialyses (HD) patients and controls at different time courses. The transcriptomic sequencing data were collected and analyzed using a solid and validated methodology. The data analysis and clinical predictors to predict anti-Spike IgG titers in HD can be a starting point for further studies characterizing the immune dysregulation seen in ESRD.

This work is a valuable presentation of sharp-wave-ripple reactivation of hippocampal neural ensemble activity recorded as animals explored two different environments. It attempts to use the fact that the ensemble code remaps between the two mazes to identify the best replay-detection procedures for analyzing this type of data. The reviewers found the evidence for a prescriptive conclusion inadequate, while still appreciating the concept of comparing maze-identity discrimination with replay.

Editors Assessment:

The hairy vetch Vicia villosa is an annual legume widely used as a cover crop due to its ability to withstand harsh winters. Here a new a 2.03GB reference-quality genome is presented, assembled from PacBio HiFi long-sequence reads and Hi-C scaffolding. After adding some more methodological details and long-terminal repeat (LTR) assembly index (LAI) analysis the assembly quality and metrics look quite convincing as a chromosome-scale assembly. This resource hopefully providing the foundation for a genetic improvement program for this important cover crop and forage species.

Editors Assessment: Aedes mosquito spread Arbovirus epidemics (e.g. Chikungunya, dengue, West Nile, Yellow Fever, and Zika), are a growing threat in Africa but a lack of vector data limits our ability to understand their propagation dynamics. This work describes the geographical distribution of Ae. aegypti and Ae. albopictus in Kinshasa, Democratic Republic of Congo between 2020 and 2022. Sharing 6,943 observations under a CC0 waiver as a Darwin Core archive in the University of Kinshasa GBIF database. Review improved the metadata by adding more accurate date information, and this data can provide important information for further basic and advanced studies on the ecology and phenology of these vectors in West Africa.

This study in budding yeast (S. cerevisiae) presents important findings demonstrating that the exonuclease Xrn1 regulates autophagy in response to methionine deprivation through effects on TORC1. There is solid evidence that the impact of Xrn1 on TORC1 is contingent on its catalytic activity rather than the degradation of any specific category of mRNAs. A major strength is the novel mechanism, in which Xrn1 modulates the nucleotide-binding state of the Gtr1/2 complex.

eLife assessment

This potentially important study examines patterns of diversity and divergence in two closely related sub-species of Zea mays, patterns that have bearings on local adaptation in maize and teosinte at intermediate geographic scales. The authors suggest that convergent evolution has been facilitated by both standing variation and gene flow, with independent selective sweeps in the two species. Limitations concerning population sampling, false positive rates in sweep detection and integration of phenotypic data at this stage only inadequately support the major conclusions. The work should in principle be of broad interest to colleagues studying the relationship between domesticated species and their progenitors, as well as those studying instances of parallel evolution.
