      In this manuscript, the authors investigate the role of histone deacetylases in the spatial epigenetic control of zygotic gene expression in early gastrulation. They discover HDAC1 binding is maternally-controlled and that inhibition of histone acetylation blocks gastrulation and disrupts cell lineage integrity, tied to both positive and negative regulatory effects on gene transcription in space and time. The study contributes to a growing body of evidence that highlights a central role of histone acetylation-deacetylation dynamics in epigenetic regulation of gene expression and cell fating in early tissue patterning of the embryo.

      When a neuron is born it correlates with where it targets in the neuropil and this has been best demonstrated in the olfactory lobe of Drosophila. This important study uses sophisticated genetics and advanced live imaging to provide a compelling description of how neuronal dendrites explore the targeting field, eliminate excessive branches, and assort into the correct region during development. In the process, it develops valuable tools. It brings us closer to a comprehensive understanding of how the birth order of a neuron translates to dendrite patterning within the Drosophila antennal lobe circuit

    1. eLife assessment

      Black et al., provide evidence that levels of Paternally Expressed Gene 10 (PEG10) protein are regulated by Ubqln2 and that proteolytic fragments from PEG10 cleavage induce changes in gene expression, in particular genes that encode proteins involved in axon biology. Based on these data and the finding of an increase in PEG10 levels and alterations of proteins regulated by PEG10 in the spinal cord of ALS patients, they propose that abnormal induction of PEG10-regulated genes is involved in ALS. However, the evidence for these claims and PEG10 involvement could be strengthened, and the rigor of the work could be enhanced in places.

    1. eLife assessment

      This important study provides a provocative potential challenge to explain sensitivity across the visual field by using cortical magnification factors. The evidence supporting this theoretical challenge is solid in general, although the inclusion of subject-specific measurements of cortical magnification factors would have strengthened the study. The work will be of interest to vision researchers of both basic and medical science.

    1. eLife assessment

      This valuable study by Pasquereau and Turner examined the activity neurons in the subthalamic nucleus (STN) while monkeys performed a task in which they had to withhold their response during a delay period whose length was defined by a specific cue. The results indicate that the activity of STN neurons was modulated by reward size and delay. The results are potentially important for understanding how STN regulates behavior such as self-control, but the reviewers thought that the study is incomplete as the analyses, at least in the presented forms, have some potential problems and some analyses require clarification.

      This manuscript reports important findings regarding the evolution of snake venom proteins. The conclusions are convincing and are based on appropriate and validated methodology in line with the current state-of-the-art. The findings will be of interest to biologists and biochemists interested in the evolution of venoms as well as those generally interested in the evolution of molecular novelties.

    1. eLife assessment

      In this potentially important study, Mahbub and colleagues examine how the small GTPase ARL15 regulates ion transport. Using a complementary array of techniques, the authors gathered solid evidence for the binding of ARL15 to CNNM proteins, resulting in a proposal how this may affect the function of the TRPM7 channel. Additional experiments are required to fully substantiate the claims.

      These authors provide compelling evidence that gestational intermittent hypoxia, a component of sleep apnea during pregnancy, increases inflammation in the spinal cords of male mice. Increased inflammation is robustly linked to deficits in respiratory plasticity both biochemically and via functional depletion assays. These data are important given the fact that male infants have worse outcomes in the NICU and are at higher risk of sudden infant death syndrome.

      Brodbeck et al. offer a timely and important contribution to how neural signals in response to continuous temporal modulations (as seen in speech and language processing) can be modelled effectively using temporal response functions. They offer a convincing new approach that includes a novel application of a boosting algorithm in addition to an accessible and didactically useful toolbox for analysis. With further comparison to existing toolboxes, or a more extensive comparison of boosting and ridge regression via simulation, this work will have a compelling impact on methods in speech and language neuroscience, as well as in cognitive neuroscience more broadly.

      This important study advances our understanding of host-derived lipid droplets' interaction with intracellular pathogens. The use of amoeba species Dictyostelium discoideum as a host for Legionella pneumophila infection is compelling and goes beyond the current state of the art, but the strength of evidence is incomplete, and the main claims are only partially supported by the data. With the experimental part strengthened, this paper would be of interest to cell biologists and microbiologists working on the interaction of microbes with host cells.

    1. eLife assessment

      This useful work describes the establishment and characterization of new cell lines derived from specific tissues of the fruit fly Drosophila. The evidence supporting the claims of the authors is solid, although the characterization of the cell lines is incomplete and the genomic findings are not presented in a user-friendly manner. These lines could be a useful resource that complements in vivo Drosophila genetics, improving biochemistry and facilitating high-throughput screening.

    1. eLife assessment

      This important study examines the association between SARS-CoV-2 infection and close contact among household members, measured using proximity sensors deployed after the first case was identified in the household. The authors provide solid evidence that transmission of SARS-CoV-2 within households is not dependent upon close contact, but the study suffers from a number of limitations that are fully acknowledged.

    1. eLife assessment

      Regulation of gene expression in many biological systems occurs either through a binary mode where gene expression is either on or off (digital regulation), or through an analog mode leading to a graded modulation of gene expression. In this manuscript, the authors report how these two regulatory modes are integrated into a one-way switch pattern to control the expression of the Arabidopsis floral repressor gene FLOWERING LOCUS C (FLC). They suggest that an analog regulation in the autonomous pathway precedes a digital regulation conferred by Polycomb silencing before cold exposure, and this temporal switch correlates with the strength of transcription at the FLC locus in different genetic backgrounds.

    1. eLife assessment

      This study combines different approaches to unravel the genetic basis of a pigmentation polymorphism in natural populations of a fascinating study system with well-studied ecology. The paper has the potential to be of general interest to biologists curious about the genetic basis of adaptive variation, which is especially relevant to evolutionary biologists and ecologists. The study reports substantial data and makes a strong case for the contribution of a duplication-derived gene acquiring a morph-specific function. Further information is required to implicate valkea in pigmentation morph formation and for diagnosing the duplicated segment as a supergene (associated with low recombination).

    1. eLife assessment

      This manuscript describes a valuable method to study the mechanism of action of essential genes and novel putative drug targets. Evidence for the effectiveness of the system, which is based on engineering pre-validated targets for RNA-mediated knockdown into genes of interest, is compelling, though some questions remain about the ease with which it can be put into general use.

    1. eLife assessment

      This study presents valuable findings from a study of identical twin pairs discordant and concordant for smoking to assess whether smoking has a direct effect on DNA methylation. The results are a valuable contribution as the study confirms the reported association between smoking and epigenetic profile is indeed due to the direct effects of constituents of tobacco smoke. The study design and methods applied by the authors are solid and provide a starting point for larger studies with rigorous laboratory approaches, as well as for assessing clinical impact. The work will be of broad interest to addiction researchers, genetic epidemiologists, and environmental scientists.

    1. eLife assessment

      This is an interesting and potentially significant study that adds important new information to our understanding of the mechanisms of lung epithelial repair after tissue injury. The authors have delineated a novel and non redundant role for the hippo pathway and the down stream regulators Yap/Taz in regulating repair of lung injury. These studies will inform future investigations into the mechanisms of repair of lung injury

    1. eLife assessment

      This study presents important results on the predicted impact of cancer screening disruptions in Australia during the COVID-19 pandemic based on consultation with public health stakeholders. The evidence presented is solid, as simulations were based on several previously validated breast, cervical, and bowel cancer screening decision models, though the scenarios were based on hypothetical disruptions that do not always match experienced disruptions. The work will be of interest to local policy-makers, public health specialists, and cancer epidemiologists.

    1. eLife assessment

      This work shows that higher socioeconomic status is associated with a higher risk of obesity, which should inform China's obesity public health programs and policies, and also be of interest to other countries and communities. The evidence supporting the conclusions is strong, but the data analysis is incomplete and would benefit from more rigorous approaches.

    1. eLife assessment

      This is important work that addresses a long-standing (but rarely acknowledged) question: given that multi-peaked tuning curves optimize Fisher information, why do early sensory areas typically have single-peaked tuning curves? This paper shows clearly, and convincingly, that multi-peaked tuning curves are likely to produce catastrophic errors at short times, so if speed is important, multi-peaked tuning curves should be avoided. This work should encourage neuroscientists to take into account the importance of stimulus encoding time in their formulations of models of neural coding.

      Endothelial cells mediate the growth of the vascular system, but they also need to prevent vascular leakage, which involves interactions with neighboring endothelial cells through junctional protein complexes. This important study provides a full mechanistic insight into how Sun1 is achieving its function, which supports the concept that nuclear anchoring is critical for proper mechanosensing and junctional organization. Although the evidence supporting the claims of the authors is solid and there are several merits and strengths in this study, a weakness is that some important controls are missing. The work will be of broad interest to cell biologists and vascular biologists.

    1. eLife assessment

      This manuscript presents a useful meta-analysis of genes with parent-specific expression from mouse published RNA-seq datasets, focusing on genes with weak allelic bias. A combination of systematic bioinformatic analysis and experimental validation convincingly shows that the number of parentally biased genes has been overestimated and the few novel ones lie at the periphery of known imprinted loci. The work will be of interest to genomicists with an interest in imprinting and its mechanisms.

    1. eLife assessment

      This study will be of interest to scientists within the field of hematopoiesis and ribosome biology. The paper provides evidence that haploinsufficiency of the mouse ribosomal protein gene Rps12 results in a number of phenotypes including defects in the production of specific blood cells and loss of hematopoietic stem cell quiescence. This work adds to the growing body of evidence that specific cell populations are particularly sensitive to disruption of mRNA translation machinery.

    1. eLife assessment

      This important paper advances our ability to understand feeding behavior in fruit flies, and begins to address the challenging question of motivation. With innovative methods based on the detailed monitoring of interactions between foods of different qualities at different hunger states, they present compelling evidence for non-homeostatic feeding not driven by metabolic need.

    1. eLife assessment

      This manuscript describes an approach for efficiently integrating diverse libraries into the C. elegans genome. The method is a valuable contribution for researchers carrying out experiments that would benefit from easy generation of such libraries, and the data for the effectiveness of the method is solid. The relative advantages of this approach in terms of ease and effectiveness relative to others with similar aims will emerge as they are put to more general use in addressing biological problems.

    1. eLife assessment

      The study has some significance for the field of dementia research and neurodegenerative diseases more broadly. Using the brain-age paradigm, the main findings are that having an older-appearing brain is associated with more advanced stages of amyloid and tau pathology, higher white matter hyperintensities, higher plasma NfL and carrying the APOE 34 allele. Findings were broadly similar in cognitively normal people and people with mild cognitive impairment and the evidence for these findings is convincing. Although sex differences are emphasized, the evidence for this is generally incomplete.

    1. eLife assessment

      This study presents important new findings regarding prenatal thalamocortical development. The authors present convincing evidence to overcome substantial methodological challenges in charting prenatal brain development in vivo. This work will be of interest to pediatric and developmental neuroscientists and neuroradiologists.

    1. eLife assessment

      The authors present valuable findings regarding the mechanism of high mannose induced cellular toxicity in cancer cells. The evidence supporting genomic instability as the anti-cancer activity of mannose is convincing with multiple orthogonal approaches showing consistent results, but the conclusions related to metabolic remodeling could be further strengthened by additional metabolomics data. While the findings are limited to genetically modified cancer cell lines cultured in vitro, this work will be of interest to cell biologists working on cancer metabolism.

    1. eLife assessment

      This potentially important study examines brain age based on resting state functional connectivity (RSFC) following an 18-month lifestyle intervention. The design of the intervention study is generally solid; the randomized controlled trial includes three intervention groups and assessments at two-time points of numerous health markers, however, the methodology for brain age prediction appears somewhat incomplete and would benefit from more rigorous approaches. The lack of control groups also prevents firm conclusions about the extent to which the observed RSFC changes are linked to the intervention. With these parts strengthened, the paper would be of broad interest to neuroscientists and biologists working on obesity, lifestyle interventions, and brain health.

    1. eLife assessment

      This paper reports a valuable new method for creating localized damage to candidate brain regions for functional and behavioral studies. The authors present solid support for their ability to create long-term local lesions with mm spatial resolution, although data supporting the extension to primates was incomplete. If the authors can demonstrate that the technique is applicable beyond the specific technical setup they employ, the paper is likely to be of broad interest to brain researchers working to establish causal links between neural circuits and behavior.

    1. eLife assessment

      This useful work proposes a framework inspired by chemotaxis for understanding how the brain might implement behaviours related to navigating towards a goal. The evidence supporting the conceptual claim is convincing, but some technical aspects are incomplete. The manuscript proposes a hypothesis that would be of interest to the broad systems neuroscience community, but the reviewers noted the relationship to existing similar hypotheses was not made sufficiently clear.

    1. eLife assessment:

      This important paper reports recent improvements and extensions to stdpopsim, a community-driven resource that is built on top of powerful software for performing simulations of population genomic data and provides a catalog of species with curated genomic parameters and demographic models. In addition to describing the new features and species in stdpopsim, the authors provide a set of simple guidelines for implementing realistic simulations. Overall, this convincing manuscript serves as an excellent overview of the utility, challenges, common pitfalls, and best practices of population genomic simulations. It will be of broad interest to population, evolutionary, and ecological geneticists studying humans, model organisms, or non-model organisms.

    1. eLife assessment

      This study presents a valuable combination of X-ray and cryo-EM structures of the bacterial adhesin PrgB, an atypical microbial cell surface-anchored polypeptide that binds DNA. There is convincing support for the claims regarding the overall function and importance of individual domains. The model for PrgB's binding of eDNA is thought-provoking, but the evidence for it based on low-resolution volumes of cryoEM data is incomplete. If additional experimental evidence for the model is produced, this work will be impactful in the field of bacterial adhesins, conjugation, and biofilm formation, and is particularly important as it focuses on a clinically important Gram-positive pathogen, whereas most work in the field has been focused on Gram-negative model systems.

    1. eLife assessment

      This paper presents valuable information on the role of type I PRMTs in programming muscle stem cell identification. The evidence presented is mostly solid, with some weaknesses in the evidence regarding the proposed mechanism.

    1. eLife assessment

      The authors have used an extensive database to study associations between biphosphanate use and COVID-19. Using careful statistical analyses biphosphonate use appeared strongly associated with a lower risk of COVID-19. If these findings are confirmed in well-designed prospective studies biphosphanate use could be an attractive drug to prevent COVID-19.

    1. eLife assessment

      This paper provides a valuable systematic analysis of proteomic profiles associated with a particular murine Ryanodine receptor abnormality. Its analysis technique provides a solid and systematic set of data summarising the differences in different muscle types. The work emerges with insights into pathological mechanism of congenital muscle diseases linked to mutations in a range of other genes related to excitation contraction coupling in workers within the skeletal muscle field.

    1. eLife assessment

      This is a rigorous and compelling extension of previous normative modeling work that demonstrates that normative models incorporating lifespan trajectories of structural and functional connectivity provide a strong basis for brain imaging studies across a range of tasks including, univariate group difference assessment, classification, and building regression models. The work is important, rigorous and a valuable contribution to the field.

    1. eLife assessment

      This study presents a useful identification of an herbal drug combination for the treatment of plasma cell mastitis (PCM), a breast inflammation with severe and intense clinical symptoms. The data were collected and analyzed using a solid and in clinical trial of 160 patients (NCT05530226) and can be used as a starting point for understanding how herbal drug combinations could be helpful in the management of PCM patients.

    1. eLife assessment

      This paper presents an analysis of both contact tracing and whole-genome sequence data to track the elimination of dog-mediated rabies in Pemba Island, Tanzania. The work is a valuable contribution to the literature as it will have practical implications for the elimination of dog-mediated rabies in other regions/contexts. The main claims made are largely supported, but the strength of evidence for the cost-effectiveness is limited.

    1. eLife assessment

      This important study presents the idea of "Skeletal Age", defined as the age of one's skeleton as a consequence of fragility fracture, as a potential new tool to raise awareness about the increased risk of mortality following a fracture (particularly hip fractures) and thus improve the medical management of osteoporosis. The evidence is convincing and is derived from a very large database from the Danish National Hospital Discharge Registry. The proposed approach might represent a starting point for making doctor-patient communication about the health risks of an osteoporotic fracture more intuitive and possibly more effective.

    1. eLife assessment

      This study presents an important finding on the cause of the widely reported disruption of the excitation to inhibition (E-I) ratio change in Autism Spectrum Disorder (ASD) mouse models. The evidence supporting the main conclusions is solid and well-sampled. These results can be a starting point for studies that assess the functional role of daily oscillations of the E-I ratio in the pathophysiology of ASD, and possibly, reshape our understanding of the nature of the E/I balance alterations that contribute to normal and diseased circuits.

    1. eLife assessment

      Understanding specific tau-tau interactions that play key roles in Alzheimer's disease and tauopathies will enable the elucidation of the toxic tau species involved in the pathogenesis of these diseases and therapeutic development in this area. In this paper, the authors developed a series of NanoBiT complementation-based tau biosensors to monitor tau intramolecular and intermolecular interactions. This paper will be of high interest to a broad target audience including researchers in the field of biophysics, biochemistry, cell biology, neuroscience, neuropathology, and drug discovery as well as physicians.

    1. eLife assessment

      This important study reveals that slow plasticity in the neocortex is essential to prevent memory interference. The method of artificially increasing plasticity in the prefrontal cortex of rats during learning and its effect on sleep physiology, when memories are believed to be reprocessed, is solid. The work will be of interest to neuroscientists interested in learning and memory.

    1. eLife assessment

      Alamia and colleagues investigate the direction of traveling waves in the alpha frequency band during visual spatial attention. The authors' novel perspective adopted here is valuable to understanding the functional relevance of alpha oscillations for spatial attention. The observed pattern of results is consistent with distinct roles for travelling alpha waves in spatially opposite directions and makes a solid case for considering this new perspective on alpha rhythms in human cognitive function.

    1. eLife assessment

      Silva and colleagues present useful findings related to the isolation of an anti-S2 antibody that recognizes a previously uncharacterized SARS-CoV2 Spike (S) epitope, adding to the growing repertoire of anti-S antibodies that broadly cross-react against human and zoonotic coronaviruses. The evidence supporting the claims of the authors is solid, although antibody effectiveness as a prophylactic or therapeutic reagent in an animal model would have strengthened the study. The work will be of interest to biologists working to develop pan-coronavirus therapies.

    1. eLife assessment

      Germline inactivation of NPHP2, which encodes a protein that localizes to the transition zone at the base of the primary cilium, results in infantile kidney cysts and fibrosis. In this study, the authors provide solid evidence that increased cell proliferation and fibrosis precede cyst formation in Nphp-2 mouse models, that mutant renal epithelial cells are responsible for the phenotype, and that genetic inhibition of ciliogenesis in this model reduces disease severity. They also show that valproic acid, a drug that affects a number of cellular targets and is used to treat other human conditions, slows disease progression. One limitation of the study is that it provides limited insights into the mechanisms responsible for any of its interesting observations.

    1. eLife assessment

      This fundamental work substantially advances our understanding of how neighboring genes on a chromosome can be separately controlled in time and space. The evidence supporting the conclusions is compelling, with state-of-the-art genetic perturbations and imaging. The work will be of broad interest to geneticists and cell biologists.

    1. eLife assessment

      This study presents a useful tool called Phantasus, a web application to analyze gene expression data generated by microarray or RNA-seq technologies. The web application will help biologists end users, and non-bioinformatics experts to analyze new data or replicate transcriptomic studies. Local use of the Phantasus through its Bioconductor package reveals an incomplete functionality concerning the current best practices in analyzing bulk RNA-seq data.

    1. eLife assessment

      In this important work, the authors present a sequence-based approach using transfer learning and Restricted Boltzmann Machines to predict antigen immunogenicity and specificity. The evidence and methodology are compelling. This work should be of interest to immunologists, computational biologists, and biophysicists.

    1. eLife assessment

      This important study demonstrates a non-canonical, cancer-cell intrinsic role of the ectonucleotidase CD73 in the regulation of cancer cell metabolism. The evidence supporting the claims is solid, although further experimental details and conditions would strengthen the evidence provided.

    1. eLife assessment

      This important study by Bonnet et al addresses the question of how AMPA receptor numbers at the synapse are regulated during basal conditions and during chemically induced Long Term Potentiation. Specifically, the study aims to determine the molecular mechanisms that contribute to the intracellular trafficking of AMPA receptors and determine their insertion into the synaptic plasma membrane. Using compelling methodology, the authors dissect the distinct roles of two proteins that bind to the C-terminal domain of the AMPA receptor subunit GluA1: 4.1N and SAP97. The findings will be of interest to anyone trying to understand molecular events contributing to synaptic plasticity in health and disease, and more broadly, the method could be adapted for tracking intracellular movements of a wide range of proteins.

    1. eLife assessment

      This manuscript significantly advances our understanding of the development of drug resistance in the HIV-1 protease. The paper addresses the fundamental relationship between resistance mutations and inhibitor structure and will be useful in the design and development of the next generation of inhibitors.

    1. eLife assessment

      This important study evaluates the immunogenicity of 3rd and 4th doses of SARS-CoV2 vaccinations in patients with cancer. Their study is notable in that neutralization of Omicron was absent in all patients after the third dose but increased to 33% after the fourth dose. With the definitions and patient population better described, this paper would be of interest to those studying the effects of repeated COVID boosters on Omicron immunity.

    1. eLife assessment

      This paper proposes a new computational model for replay that is biologically realistic and accounts for a number of important phenomena in hippocampal replay. This is an important study with implications for multiple subfields. Whilst the majority of claims are convincingly supported by the data, simulation analyses for some crucial aspects of replay literature are currently incomplete.

    1. eLife assessment

      The authors developed a two-photon fluorescence microscope coupled with adaptive optics (AO-2PFM), allowing in vivo imaging of the mouse retinal structure and function. This new imaging system will be important for exploring normal retinal physiology and pathological alterations in retinal disease models.

    1. eLife assessment

      The overarching question of the manuscript is important and the findings inform the patterns and mechanisms of phage-mediated bacterial competition, with implications for microbial evolution and antimicrobial resistance. The evidence in the manuscript is, however, still incomplete and some of the conclusions made are not supported by the data. This manuscript would additionally be strengthened by a clearer narrative, to enable readers to more easily extract the key message this paper wants to convey.

    1. eLife assessment

      This is a well-done study to understand how Rab27 and its effectors regulate insulin secretion. The present work examines the relative hierarchy of exophilin-8 and melanophilin using single vs double knockouts and rescue experiments to show that melanophilin functions downstream of and potentially redundantly from Exo8. Imaging and protein co-localization studies were done in a rigorous way. The data are solid, and some additional data will make the work fully compelling. Overall this is an important study that sheds new light on the regulation of insulin granule exocytosis.

    1. eLife assessment

      This study presents a valuable finding on the role and function of the Gaq axis on the inflammatory response during decidualization essential for early pregnancy. The evidence supporting the claims of the authors is solid, although some of the methodology and data interpretation require further clarification and justification. The work will be of interest to reproductive biologists and clinicians.

    1. eLife assessment

      This important study reports Foxc2+ cells in the testis might be the true spermatogonial stem cells (SSCs). The data supporting this claim are solid and the finding, if proven true, would have a great impact on reproductive biology and stem cell biology as the genes responsible for maintaining the quiescent state of SSCs during spermatogenesis remain elusive.

    1. eLife assessment

      This paper reports valuable data on a classic model for cell fate specification in the C. elegans gonad. The data, though extensive, provide so far incomplete support for the major claims of the paper, especially regarding the functional significance of their conclusions. The paper 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 condensates are resolved.

    1. eLife assessment:

      This manuscript describes development of a new algorithm for integrative analysis of multi-omics data. This work should be of potential interest to scientists performing bioinformatic pathway discovery in multi-omic datasets especially those that relate to signaling.

    1. eLife assessment

      This manuscript presents valuable findings that bring together two important topics in cell biology: the function of membrane contact sites and cell migration. The authors describe a role of the ER tether protein VAP-A in focal adhesion dynamics and cell motility. Although the authors present solid evidence to support some of the main claims of the paper, some of the other claims would benefit from stronger experimental support. Nonetheless, this paper will be of interest to those cell biologists and biophysicists working on adhesion, migration, and membrane contact site biology.

    1. eLife assessment

      This paper is of interest for skeletal biologists studying bone marrow stem/progenitor cells and bone remodeling. Using Adipoq-Cre-driven conditional deletion of Csf1 that encodes M-CSF and reanalyzing publicly available scRNAseq data, the authors recognize a subpopulation of bone marrow cells (i.e. AdipoQ-lineage progenitors) as an important source of M-CSF. The authors found that M-CSF production from these bone marrow cells influences the development of macrophages and osteoclasts as well as bone mass, including the bone loss associated with estrogen deficiency. This is a clearly written and nicely presented study that has potential to offer important new information regarding the source of M-CSF in the bone marrow.

    1. eLife assessment

      This study provides a valuable data resource to study the systemic effects of severe COVID-19. It shows compelling evidence that the transcriptional response to COVID-19 is coordinated across the body, and it highlights cell interactions between macrophages and endothelial cells in COVID-19. This analysis and the associated resource will be valuable to understand the pathogenic mechanism of long-COVID.

    1. eLife assessment

      This important study develops a new technical advancement in ex vivo live imaging of hematopoietic tissues to monitor blood cells in their native microenvironment. The new method for live imaging and tracking is compelling, and the strength and breadth of hematopoietic analysis are convincing. This work provides a very useful new system for immunologists and cell biologists, which will supply new perspectives on the system-level mechanisms of cell differentiation and innate immunity.

    1. eLife assessment

      This paper is of interest to immunologists conducting single-cell analyses of T-cell recognition. It provides a means of curating datasets to ensure T cell-antigen pairs are identified. The data generated through this method often suffers from a relatively high background, so the authors present a computational approach to enhance the signal-to-noise of this type of analysis. At this stage, it is unclear if the thresholds and filtering steps described by the authors can be generally applied to other datasets of different qualities than the one used here.

    1. eLife assessment

      This study presents a valuable mathematical model for the adaptive dynamics of cancer evolution in response to immune recognition. The mathematical analysis is rigorous and convincing, and overall the framework presented could be used in the future as a solid base for analytically tracking tumor evasion strategies. However additional discussion is needed to clarify certain gaps between the theory and cancer evolution in real systems. The work will be of interest to evolutionary cancer biologists and potentially it may also have implications for the design of clinical interventions.

    1. eLife assessment

      This study presents a valuable finding on the critical features and patterns of m1A modification and in neurons and OGD/R-treated neurons. Moreover, the authors identified m1A modifications on different RNAs and explored the possible effects of m1A modification on the functions of different RNAs via an integrated approach of omics and bioinformatics. The evidence supporting the claims of the authors is solid, although inclusion of more in-depth studies to analyze the transcription factors for the upstream regulation would have strengthened the study. The work will be of interest to neurobiologist and scientists in the field of RNAs.

    1. eLife assessment

      Scott et al use Drosophila as a model to study the sialylation pathway and its role in nervous system function. Surprisingly, they find that the critical substrate for sialylation, CMP-Neu5Ac, is 'outsourced' to glia. This significant study presents a new twist in mechanisms underlying protein glycosylation and uncovers a new layer in the complex interplay of neurons and glia.

    1. eLife assessment

      This work is an attempt to establish conditions that accurately and efficiently mimic a drought response in Arabidopsis grown on defined agar-solidified media – an admirable goal as a reliable experimental system is key to conducting successful low water potential experiments and would enable high-throughput genetic screening (and GWAS) to assess the impacts of environmental perturbations on various genetic backgrounds. The authors compare transcriptome patterns of plants subjected to water limitation imposed using different experimental systems. The work is valuable in that it lays out the challenges of such an endeavor and points out shortcomings of previous attempts. However, a lack of water relations measurements, incomplete experimental design, and a lack of critical evaluation of these methods in light of previous results render the proposed new methodology inadequate.

      This study links chromatin remodeling with antifungal drug resistance in Cryptococcus neoformans. The work is important because it reveals a new facet of how drug resistance can emerge and associates. The work presented is well done but the story is incomplete since there are questions about methods and association that need to be addressed. Establishing a link between chromatin remodeling and antifungal resistance is a finding that would be of interest to infectious disease researchers, cell biologists, and drug developers.

      There are many strengths in this paper that examines patterns of epididymal blood and lymphatic vasculature, supported by quantitative methods, and well-conducted 3D imaging studies (graphics and videos). Minor weaknesses include the lack of higher magnification images and the organization of image panels in some figures. Overall, this is a very important contribution to the epididymis research field.

    1. eLife assessment

      This study, of interest to population geneticists and evolutionary biologists alike, aims at investigating temporal variation in patterns of germline mutation during the evolution of human populations. The authors suggest that shifts in mutation spectra occur frequently, over a few thousands of generations, possibly as a consequence of changes in environmental exposure, or of genetic modifiers. There are several important aspects of methodology that need to be clarified, and several additional tests have to be done to confirm that the reported observations are not the result of methodological artifacts. The paper also overstates certain weaknesses of previously published papers on mutation spectrum evolution as well as the generation time hypothesis; correcting these oversimplifications would more accurately capture what the paper's new analyses add to the state of knowledge in these areas.

      This manuscript provides compelling evidence that macrophages transfer mitochondria to cancer cells and that transferred mitochondria stimulate proliferation in recipient cells. The usage an array of clever cell biology-based tools provides compelling evidence for these claims despite the difficulties associated with studying a relatively low probability event. Solid evidence supports the proposed model that transferred mitochondria induce proliferation by stimulating ERK signaling in a ROS dependent manner, although at present some aspects of the proposed model are incomplete. The work has broad significance for both mitochondrial biology and cancer biology as the authors show clear evidence of mitochondrial transfer in mouse models of human tumors.

      Opioid-induced respiratory depression is one of the side effects of opioid drugs. Although opioid overdose deaths are highly prevalent, our knowledge of the neural circuits underlying respiratory depression in the brainstem is far from complete. The present study used a variety of sophisticated experimental techniques to convincingly reveal the identity of brainstem components that are part of the neural circuits involved in the mediation of opioid respiratory effects, together with defining potential synaptic underlying mechanisms. They focused on two regions of the brainstem, namely the Kolliker-Fuse and the preBötzinger Complex, and proposed a combination of three complementary processes at pre- and post-synaptic sites in both KF and preBötC regions to explain respiratory depression linked to opioid exposure. This study provides very important findings on the circuitry involved in opioid-induced respiratory depression, and the present results are of broad interest to the respiratory control research community, as well as medically relevant.

      Bone marrow stromal cells (BMSCs) can differentiate into a variety of cell types such as osteoblasts, chondrocytes, and adipocytes. The authors of this important study provide compelling and strong evidence that ablating O-GlcNAc transferase (OGT) in BMSCs impairs bone formation but promotes marrow adiposity. The results show that the balance of osteogenic and adipogenic differentiation of BMSCs is controlled by reciprocal O-GlcNAc regulation of lineage-specifying transcription factors, and highlights the importance of an intracellular glycosylation process of specific proteins in bone formation and bone marrow adipocytes.

      The analysis of 89,000 independent somatic mtDNA mutations provides compelling evidence that allows the authors to refute the idea that reactive oxygen species (ROS) are a main driver of mtDNA mutagenesis, although ROS effects may still be tissue-dependent. These are fundamental results with convincing evidence, and they should appeal to a broad audience. The discovery of transversion mutations (C>A/G>T and C>G/G>C), which previously were assumed to be almost nonexistent, will nevertheless require additional validation.

      This important study advances our understanding of the composition and circuit organization of the preBötzinger complex (preBötC)-the brainstem region that generates the respiratory rhythm and coordinates breathing with different motor and physiological behaviors in mammals. The reviewers agreed that the evidence supporting the conclusion that the preBötC is composed of a segregated subgroup of output neurons that modulates orofacial muscle activity is compelling and based on technically elegant, state-of-the-art combinatorial dual viral transgenic and optogenetic approaches in rats. After the cytoarchitectonic analyses are strengthened, the work will be of interest to neuroscientists and physiologists working on the neural control of breathing and other motor systems.

      This study on snapping shrimp morphological weaponry presents important findings on trade-offs in investment in costly weaponry traits as related to body size and reproduction. Convincing evidence is based on the collection of an exceptional number of fields samples, the inclusion of three shrimp species, and the measurement of numerous morphological and behavioral traits. The evidence shows that there are size-dependent trade-offs, where males and females differ in weapon investment, as weapons are beneficial to males but expensive for females. The findings will be of broad interest to evolutionary biologists and researchers working in the field of animal behavior.

      This manuscript will be of interest to centrosome and cilia cell biologists. It evaluates the in vivo and in vitro role of PCM1, and by extension, centriole satellites in ciliogenesis. The major strength of this study is the detailed characterisation of Pcm1-/- mutant mice, which reveals a role for PCM1 in biogenesis of specific types of cilia, such as motile cilia on ependymal cells. The claims are generally well supported by the data, but the mechanistic basis for the cell-type specific requirement for PCM1 in ciliogenesis remains to be fully clarified.

      The RNA-binding protein Tristetraprolin (TPP) regulates the abundance of mRNAs encoding proinflammatory cytokines. The study by Scinicariello and collaborators examined mechanisms regulating the turnover of TTP in cultured cells and identified the ubiquitin E3 ligase HUWE1 as a regulator of TPP degradation. The conclusions are largely supported by the cellular and biochemical experiments. This paper thus implicates the HUWE1-TPP axis in regulating macrophage inflammatory responses at the post-transcriptional steps.

      During meiotic prophase I, protein complexes essential for crossover recombination are distributed non-randomly along chromosomes. With mathematical modelling and based on results from super-resolution microscopy, the authors introduce a second type of coarsening of protein ensembles between chromosome axes and nucleoplasm between chromosomes and nucleoplasm to support the random distribution of the complexes in the synapsis-defective mutant. The new model is interesting and may be applied to other chromosomal events accompanied by the formation of large protein ensembles on the chromosomes. The work is of interest to colleagues studying recombination and meiosis.

      This extraordinary study mapped the circuit architecture of a brain module for learning and memory in the octopus brain. In particular, one gyrus of the Octopus vulgaris brain vertical lobe was imaged with volume electron microscopy, its neurons reconstructed and their synapses mapped. The acquisition of this pioneering data set was followed by a very convincing analysis of the circuits supporting learning and memory, and therefore behavioral plasticity, in this animal. The data and findings establish an important point of comparison with analogous brain structures in other organisms, such as the vertebrate cerebellum and the arthropod mushroom body, offering a new neural circuit architecture to support the study of behavior and inspire the design of artificial neural networks.

      Overall, this manuscript provides fundamental advances to our understanding of the ancestry of insect gustatory and olfactory receptors, by identifying new members of these two related ion channel families in distant species. The approaches to compare protein structure are exceptional and use cutting-edge techniques, going beyond the commonly used approaches. The authors suggest that the family of odorant and gustatory receptors have a common origin and share structural homology in very distant organisms, although the possibility of convergent evolution still exists. This work will serve as a reference for scientists working on insect olfaction and for those working on molecular evolution.

      In this important article, the authors characterize ancient DNA from maize unearthed in archaeological contexts from Paredones and Huaca Prieta in the Chicama river valley of Peru, recovered by painstakingly controlled excavation. The genetic evidence is compelling, albeit from a small sample size, but the dating evidence, despite the excellent archaeological context, is inadequate. Since the age of the samples is so important for the inferences, the individual radiocarbon determinations should be subject to further scrutiny.

      This is a valuable initial study of cell type and spatially resolved gene expression in and around the locus coeruleus, the primary source of the neuromodulator norepinephrine in the human brain. The data are generated with cutting-edge techniques, and the work lays the foundation for future descriptive and experimental approaches to understand the contribution of the locus coeruleus to healthy brain function and disease. However, due to small sample size and the need for additional confirmatory data, the data only incompletely support the main conclusions presented here. With the strengthening of the analyses, this paper, and the associated web application, will be of great interest to neuroscientists working on arousal-based behaviors and neurological and neuropsychiatric phenotypes.

      The authors have combined their two recently developed novel approaches to Mendelian randomization studies (1) Lifecourse mendelian randomization which relates genes to the outcome, eg obesity, at different stages of life, and (2) Tissue partitioned mendelian randomization to determine if there are different genetic effects in different tissues. They have successfully combined these two approaches to investigate the influence of adiposity on circulating leptin in childhood and adulthood to demonstrate the value/proof of concept of combining these two techniques. This is very clearly presented and well-conducted work showing both new methodology and compelling results and will be important to both those who use Mendelian randomization and those who are interested in obesity.

      This study provides evidence that the Stromalin Antigen (SA) proteins known to ubiquitously interact with cohesins, retain their capacity to bind CTCF and chromatin in the absence of RAD21 cohesin component. Authors imply that SA has an independent function in addition to its joint role with RAD21 and CTCF, providing experiments that make them suggest that SA proteins organize around RNA:DNA regions in the absence of cohesin, contributing to R-loop regulation and linking chromatin on structure to cohesin loading. The paper is a nice piece of work of interest to readers in the field of cohesin biology and genome organization. However, additional, experiments would be required to strengthen some of the conclusions.

      Signaling mediated by Semaphorins and their receptors Nrp1 and Nrp2 is crucial for regulating the morphology of dendritic spines and dendritic arborization during development. In this manuscript, the authors found that the post-translational modification of S-palmitoylation dictates the subcellular localization and trafficking of Nrp2, but not Nrp1, and is required for Sema3F-dependent pruning of spines on the apical dendrites of layer V cortical neurons. The study provides important insights into how semaphorin signaling achieves spatial specificity on diverse downstream cellular events.

      The authors state that there is scant experimental evidence of divisive normalization of neural responses in the human brain. They used fMRI BOLD response to high-level stimuli to explore normalization in V1, object-selective (LO and pFs) and category-selective regions (EBA and PPA) as well effects of attention on cortical responses. Specifically, the authors first test the degree to which BOLD responses to body parts and houses exhibit responses predicted by a non-linear normalization model, compared to two linear models (weighted sum and weighted average). They find that responses, when considering responses to one vs two stimuli, are best fit with the normalization model. They then suggest that object-based attention effects can be better accounted for by a normalization model of attention, compared to attention variants of the aforementioned models. The paper could potentially be an important contribution to the fields of perceptual and cognitive neuroscience, but the conclusions are not sufficiently supported by the data at this stage. Several theoretical and methodological concerns limit the conclusions of this study.

      This manuscript makes a valuable contribution to the field. The authors have developed a compelling network model to study mechanisms for the emergence of oscillations in the beta range in the primary motor cortex during movement preparation, and their propagation as traveling waves across the cortical sheet. The model is able to recapitulate several features of motor cortical activity acquired experimentally. Due to the recent results suggesting a functional role for traveling waves, it is of great interest to discover the mechanisms underlying such phenomena, and this work is an interesting step in that direction. However, the evidence for the reported new insights is incomplete at this stage, due to some weaknesses that remain to be addressed.

      This paper will be of fundamental interest to many sub-disciplines of neuroscience, ranging from cognitive neuroscientists to cellular neuroscience. It provides compelling and substantial brain and behavioral evidence of a novel intervention that can boost long-term memory. The key claims of the manuscript are generally well supported by the data, though the correlational nature of the data in different types of experiments raises some issues about interpretation.

      The authors present interesting information regarding the possibility of targeting the oncogenic K-Ras(G13C) mutant with nucleotide competitors. The experiments represent a solid support of the claims and show that this approach can work despite concerns about the high affinity of GTP and its high cellular concentration. These results will be of high interest for all working in the Ras field and in targeting oncogenes with small molecules. A weakness of the manuscript is the lack of direct physiological insights.

      This manuscript will be of interest to a wide range of cell biologists interested in understanding cell-cell communication. The discovery that an engulfing cell can control the extrusion and degradation of large vehicles from its target cell is important and intriguing. The authors present compelling data that show that exophers (large neuronal extrusions proposed to discard toxic cargo) are taken up by adjacent hypodermal cells, split into smaller fragments, and eventually degraded by lysosome fusion. The authors identify a number of small GTPases and accessory components, as well as the phagocytic receptor (CED-1) and the likely eat-me signal (phosphatidylserine).

      The manuscript proposes a mechanism by which different S-adenosylmethionine (SAM) synthase enzymes exhibit specificity towards target sequences, thereby proposing a novel layer of control over H3K4 trimethylation (H3K4me3). Such specificity is demonstrated in the context of responses to heat stress for two Caenorhabditis elegans SAM synthase enzymes, supporting the existence and importance of this novel mechanism of epigenetic control.

      The authors document an in-depth analysis of introduction patterns of 5 variant waves in Mexico. This is an important analysis and dataset since the genomic epidemiology of SARS-CoV-2 in Mexico is generally understudied, and this paper contributes important missing information. The phylogenetic analyses are solid and well-presented, but the lack of detail regarding the collection of samples across Mexican states makes it difficult to evaluate conclusions about the relationship between observed viral lineages and local case counts. Additionally, in its current form, the manuscript is mostly descriptive, without clear hypotheses tested or discussion of implications.

      This important work advances our understanding of the factors that affect the speed of colour evolution in birds and the resulting diversification patterns. It provides compelling evidence that more complex plumage coloration can lead to rapid colour evolution in kingfishers, and could pave the way for more comprehensive analyses that fully embrace the multidimensional nature of colour variation. Hence, the results will be of broad interest to ornithologists and evolutionary biologists in general, once the authors have streamlined the theoretical framework and explained the novel methodological approaches in more detail.

      This valuable manuscript describes a fully automated touchscreen cognitive testing system for rats that reduces the length of training required to learn a task and eliminates the need for daily handling. These features make it possible to assess cognitive behaviors in conjunction with other neurobehavioral paradigms during adolescence, an important advance in the field. The data convincingly show that cognitive flexibility does not promote susceptibility to severe weight loss in the activity-based anorexia (ABA) paradigm. However, support for the claim that cognitive deficits seen in rats that had been exposed ABA adequately capture an important clinical feature of the pathophysiology of anorexia nervosa is incompletely supported.

      This study provides fundamental insights into the relationship between single neuron activity in superficial layers of the cortex and electrical signals recorded at the cortical surface. Based on solid measurements, the results indicate a weak correlation between individual layer 2/3 neuron activity and multiunit activity recorded at the surface, whose interpretation could be reinforced. In particular, a strong contribution of layer 1 axons to surface signals is suggested but relies on incomplete evidence.

      This manuscript provides valuable insight into the molecular mechanism by which destabilized mitochondrial proteins 'clog' import channels and contribute to the pathologic mitochondrial and cellular dysfunction implicated in human disease. The evidence supporting this conclusion is solid, utilizing yeast, mammalian cell culture, and mouse models. However, additional characterization of import clogging in the mammalian model systems would strengthen this study. This work will be of broad interest to researchers in the fields of mitochondrial biology, protein quality control and proteostasis.

      This manuscript tests an important assumption about how sensory information is processed and used to guide motor choices. The widely held assumption is that sensory-motor circuits are capable of integrating evidence, but the validity and generality of this 'principle' have been recently questioned by studies suggesting that other computational operations may lead to similar psychophysical results, mimicking integration without actually performing it. This study makes a compelling case that the integration assumption was likely correct all along and that the model mimicry can be easily disambiguated by using appropriate sensory stimuli and task designs that permit rigorous analyses.

      This important study provides convincing evidence that locus coeruleus is activated during visuomotor mismatches. Gain of function optogenetic experiments complement this evidence and indicate that locus coeruleus could be involved in the learning process that enables visuomotor predictions. This study therefore sets the groundwork for the circuit dissection of predictive signals in the visual cortex. Loss-of-function experiments would strengthen the evidence of the involvement of locus coeruleus in prediction learning. These results will be of interest to systems neuroscientists.

      The paper provides a valuable, in-depth mathematical analysis of the coevolutionary dynamics resulting from a coupling of players' strategies and (collective) risk, as well as illustrative numerical simulations of the system's trajectories for different starting conditions. It is therefore a solid contribution to our understanding of how cooperation can be sustained when there is feedback between individual decisions and the global risk of disaster. This paper will be of interest to scientists working on mathematical biology/ecology, and more generally various aspects of human decision-making, the interplay between human decisions and the environment, and public goods provision.

      This manuscript reports novel and important findings on the mechanisms of regulation of CRAC channels. Collectively, the work represents an important conceptual advancement, showing that stromal interaction molecule-1 is not necessary for Ca2+-dependent inactivation of the Orai1 channel and that Orai1 likely contains a Ca2+ sensor for autoregulatio. The experiments are carefully conducted, and the data is of high quality and support the major conclusions of the authors.

      This important paper advances the understanding, in the model plant Arabidopsis thaliana, of the molecular basis of the promotion of flowering in the spring by exposure to winter cold through a process known as vernalization. In Arabidopsis, there are two classes of long non-coding RNAs produced only when plants are in the cold, and this work provides compelling evidence that the cold-induced expression of one of these (COOLAIR) involves C-repeat binding factor proteins that bind to cognate binding elements in the COOLAIR promoter, but also that COOLAIR is not required for the vernalization-mediated promotion of flowering under standard laboratory conditions in which the vernalization response is measured.

      This study provides fundamental insight into the functional impact of CDK4 inhibition on cells in the tumor microenvironment, which is of high importance and interest to the field. The compelling conclusion that proliferative exhausted T cells are associated with response in HPV+ head and neck cancer is supported by the cohort of 14 patients with paired tumor and adjacent normal tissue and rigorous bioinformatic analysis of nearly 50,000 single CD3+ T cell transcriptomes. This work will be of interest to researchers across tumor types and in other immunological fields of study.

      In this work, the authors provide convincing evidence about the existence of two distinct osteoclast populations with specific expression profiles and properties and show that the probiotic yeast S. boulardii may be useful in managing inflammation-mediated bone loss, including estrogen deprivation-mediated osteoporosis. The reported study aims to bring the concept of heterogeneous osteoclasts into a proof-of-principle therapeutic application, which may mean that the use of probiotics might combat osteoporosis towards a better bone quality than current therapies. The molecular mechanism of how the probiotic yeast S. boulardii treatment acts via the receptors remains obscure since it might act via changes in the gut permeability or by components directly released by the fungus.

      This paper will be of considerable interest to researchers studying the psychological and neural basis of variation in prosocial behavior. The authors use a sophisticated combination of computational modeling and EEG to show that variation in generosity produced by changes in context (i.e., disadvantageous vs. advantageous inequality) and variation due to individual differences in concern for others both seem to occur early, during the perceptual or valuation stage of a choice, rather than later on during choice comparison. However, these two sources of variation also appear to operate through distinct mechanisms during this stage of processing, which spurs further questions about the drivers of human prosocial behavior.

      The authors examine the function of Tomosyn, in dense core vesicle fusion in neuronal cultures from mice expressing conditional alleles of tomosyn and tomosyn-2. The authors show here that while loss of tomosyns did not affect dense core vesicle exocytosis, it reduced the expression of several key dense core cargos, including BDNF. However, "rescue" experiments are needed to validate the specificity of the effects.

      This study describes the use of a new and valuable tool, namely phage display of Plasmodium falciparum proteome-wide peptides, for profiling of antibody targets. The study, conducted using plasma from Ugandan children and adults, represents an important aspect of naturally acquired antibodies with seroreactive responses to the intra-and inter-protein repeat regions. The results are, however, so far incomplete, and confirmatory data that antibodies to inter-protein repeat motifs do cross-react are needed.

      This highly important paper uses a Bayesian linear regression approach in a clinical trial to establish that ivermectin does not increase the clearance rate of SARS-CoV-2 relative to no study drug. The strength of evidence is compelling. Particular strengths are that the paper is clearly written, a novel and important adaptive study design, and linear mixed modeling to account for participant heterogeneity. The work will be of interest to clinicians, statisticians, and public health departments.

      In this manuscript, the authors devised a new, useful mRNA-imaging approach by combining MS2 and SunTag labeling systems. The authors showed that this new method can be used to image the activation of gene expression and endogenous mRNA dynamics in live C. elegans. While the application in C. elegans has great future potential, this study is incomplete because it lacks essential characterization of the new imaging method to demonstrate that it does not interfere with RNA expression.

      The study is important in that it investigates the effect of reading acquisition on neural responses experimentally, randomly assigning children to one of two training groups. The results provide solid evidence for learning-related changes in the (late) neural response to words, but it is not clear whether this reflects category-specific changes in visual cortex tuning. As such, the study may not yet provide a clear answer to the neuronal recycling debate within which it was framed. This paper is of potential interest to a broad audience of neuroscientists, as it addresses fundamental questions regarding the re-organization of functional cortical responses associated with learning to read.

      This study presents important findings on the regulation of the phosphate export cycle and identify the phosphatase Sit4 as a crucial player in regulation of the inner membrane potential of mitochondria. Whereas some of the data are convincing, the analyses will profit from deeper insights concerning metabolism alterations (carbon sources, amino acids). The major strength however is a new insight on how the cells use alternative ways for maintaining a critical mitochondrial inner membrane potential, and therefore this study is interesting to the broad audience with interests spanning from bioenergetics, metabolism and organellar and cell biology.

      The study is a careful investigation of the physical properties of hagfish slime and the underlying cellular framework that enables this extraordinary evolutionary innovation. It is a careful and detailed measurement with clear images. However, there is a need for a better contextualizing of the findings as a broader biological question, including the evolution of functional novelty, the adaptive processes, and the links between genetic and phenotypic evolution. Furthermore, the conclusions on the evolutionary origins and underlying genetics of hagfish slime based on comparative transcriptomic data need to be better supported.

      This important analysis helps to shed light on the relationship between blood type and the occurrence of ICD-based phenotypes in a hospital setting. A particularly compelling strength is the analysis' reliance on a population-based patient registry. The results would be further strengthened by an exploration as to whether these phenotypes are driven by patient characteristics (e.g. ethnicity, SES) and not just blood type. Additionally, differences across blood types are driven, in part, by differences in prevalence, somewhat limiting the scope of the analytical findings.

      The study shows that human inflammasome-forming sensor CARD8 contains a specific motif that allows cleavage by the proteases of HIV-1 and its direct precursor infecting chimpanzees. In comparison, CARD8 proteins from non-human primates contain changes in this motif and seem largely resistant to proteolytic activation. The results are important, and the data on the cleavage of CARD8 in HEK293T cells are convincing, while effects on inflammasome stimulation and cell death in primary viral target cells are insufficiently supported.
