Evaluation Summary:
This paper will be of interest to neuroscientists interested in predictive coding. By using complementary neuroimaging and electrophysiological methods to measure brain-wide activation patterns in marmosets in response to sound pattern violations, the authors provide evidence for the hierarchical organization of predictive coding across subcortical and cortical levels of the auditory pathway.

Evaluation Summary:
This is very much needed work, especially in light of the recent debate regarding whether or not microsaccades are the cause of peripheral attentional effects. A few influential papers have been published recently strongly suggesting that attentional effects are primarily the result of the execution of tiny microsaccades that humans/primates perform during fixation while attending to peripheral stimuli. These past findings have, naturally, a number of implications for the way we interpret visual attention, and raised the question of whether shifts of attention are dependent on microsaccades. By explicitly comparing and quantifying the effects of attention on neuronal responses in the presence and in the absence of microsaccades, this work provides important insights into this debate.

Evaluation Summary:
This paper is of interest to researchers studying muscle function in the nematode C. elegans and to researchers interested in muscle aging in humans. The work documents the importance of C. elegans alh-6, which encodes a proline catabolic gene, in limiting muscle stress and maintaining locomotory function in aging nematodes. Further work implicates GWAS SNPs in the human homolog ALDH4A1 as potential determinants of specific muscle decline indicators. The suggestion of a conserved role for ALH-6 in aging humans could underlie establishment of a useful biomarker for older age muscle-associated health. However, while the work expands on and reinforces findings in C. elegans, it does not yet rigorously demonstrate a role for ALDH4A1 in muscle function in aging humans.

Evaluation Summary:
This study using single cell RNA Seq to profile developing retinal ganglion cells from embryonic and postnatal mouse retina explores the diversification of this class of neurons into specific subtypes. The computational approaches developed identify groups of RGC precursors with largely non-overlapping fates, distinguished by selectively expressed transcription factors that could act as fate determinants. The aim is to show that over time, clusters of cells become "decoupled" as they split into subclusters, and this process is associated with changes in the expression of specific transcription factors. This leads to the proposal that subtype diversification arises as a gradual, asynchronous fate restriction of postmitotic multipotential precursors. These findings enable the prediction of lineage relationships among RGC subtypes and the developmental time when these specification events occur, and should be of great interest to the developmental neurobiology community.

This paper will be of interest to a broad audience of epidemiologists and early childhood researchers as it provides data on the relationship between infection burden in infancy and metabolomic/lipidomic profiles at 12 months of age from a unique cohort of 555 mother-infant dyads. The paper also examines potential biologic pathways that may inform prevention of cardiovascular disease. The series of analyses presented support the preliminary associations outlined and require validation and interventional studies to support the causal relationship between infection, cumulative inflammation burden, and atherosclerosis.

In a set of in vitro and in vivo experiments the investigators demonstrated that coating of urinary tract catheters with fibrinogen-degrading substances reduced adhesion and colonization with a broad range of bacteria relevant in the pathogenesis of CAUTI. This approach might, therefore, be interesting for prevention of CAUTI as an alternative to catheters coated with antibiotics.

One hypothesis to explain recent worse-than-expected outcomes of universal test-and-treat HIV prevention trials is population mobility. The authors show phylogenetically that mobility could play a role in transmission events in a large trial in Botswana. This study is of public health interest, has a large sample size for a phylogenetic study in this setting, and overall precise analysis. A few methodological clarifications are still needed to ensure that the data supports the study's claims.

This paper will be of broad interest to neuroscientists, providing a rich resource for future research. Using available RNAseq data the authors build an easy-to-work-with web platform which will enable researchers to survey the expression patterns of palmitoylating and de-palmitoylating enzymes and their potential co-expressed substrates within the mouse nervous system. Using this map, the authors test hypotheses about the relationship between these enzymes and neurological diseases and generate hypotheses about enzyme/substrate relationships based on expression correlations.

Evaluation Summary:
Matityahu et al investigate the influence of nicotinic acetylcholine receptor signaling on striatal microcircuit function through a combination of slice electrophysiology, optogenetics, and pharmacology. They find that nicotinic signaling delays spiking of striatal projection neurons in response to excitatory input, likely through the tonic release of acetylcholine by cholinergic interneurons onto local GABAergic interneurons and their influence on striatal projection neurons. Understanding how acetylcholine shapes striatal circuits is important, as this neurotransmitter is implicated in multiple movement disorders as well as other basal ganglia-related diseases.

Bitzenhofer and colleagues provide unprecedented details of odor response properties of layer 2 cells in LEC. The authors show that firing rates of LEC ensembles conveyed information about odor identify whereas timing of spikes odor intensity and that, on average, fan cells responded earlier than pyramidal neurons, and pyramidal neurons, but not fan cells, changed their peak timing in response to changes in concentrations, providing a basis for temporal coding of odor concentrations. The results provide important information about odor coding in LEC, an understudied area of the brain.

Evaluation Summary:
This study describes work measuring transcriptional changes through development and later aging. The authors broadly conclude that the transcriptomes of several tissues diverge during development, but re-converge during aging, a pattern that they term "divergence convergence", or DiCo. The trajectories the authors have identified could provide a powerful lens through which to improve our understanding of the basic biology of aging. This paper will be of interest to the aging community, especially to researchers interested in age-dependent gene expression changes and their consequences.

Evaluation Summary:
The oncogenic virus Human Papillomavirus encodes the E7 protein which is an important contributor to carcinogenesis. Here, the authors show that E7-mediated degradation of the cellular tumor suppressor PTPN14 leads to activation of YAP1 in basal cells of the stratified squamous epithelium. They show that the ability of E7 to extend the lifespan of keratinocytes and facilitate basal cell retention are both activities mediated by the basal-cell specific activation of YAP1 and conclude that this newly discovered function of HPV E7 contributes to its carcinogenic properties. This report will be of great interest for researchers in the HPV and epithelial differentiation fields.

Evaluation Summary:
This paper describes analysis and modeling of leading edge fluctuations in migrating cells driven by a branched Arp2/3 lamellipodial network. A stochastic model shows how branching contributes to shape stability, and reproduces the measured spectrum and dynamics of leading edge fluctuations. Analysis of the model as a function of branching angle suggests that the Arp2/3 branching angle might be selected to smooth lamellipodial shape. The authors provide new ideas to a big field of research, including Fourier analysis of leading edge fluctuations, which is a novel approach. The modeling methods and model design seem valid and the paper is well written.

TRPV4 is an ion channel protein and mutations in TRPV4 gene resulted in different types of skeletal defects. In this study, the authors created two types of TRPV4 mutations (mild V620I and lethal T89I mutations) in human iPS cells through CRISPR-Cas9 gene editing. They identified key molecules potentially involved in TRPV4 mutation-induced changes in chondrocyte activities and concluded that the inhibition of chondrocyte hypertrophy induced by the mutations may cause the bone diseases.

This paper will be of great interest to researchers interested in the brain mechanisms of pain. It shows how the connectivity of brain networks associated with sustained pain change over time. These findings are conclusively supported by state-of-the-art fMRI analyses of a tonic pain paradigm in two cohorts of healthy human participants. These insights are important for the understanding of the brain mechanisms of sustained pain which is the hallmark of chronic pain as a major health care problem.

Evaluation Summary:
Padoa-Schioppa and colleagues describe possible neuronal correlates of behavioral biases observed in monkeys making value-based choices when options are presented simultaneously versus sequentially. Building on the lab's previous work detailing functional roles of different neurons in the orbitofrontal cortex, the authors relate different choice biases to different groups of OFC neurons. They propose that these relationships indicate that different biases are likely to arise from specific stages of decision computation. The study results are convincing and represent a significant advance in understanding circuit-level computations underlying decision-making.

Evaluation Summary:
FGF2 moves directly from the cytoplasm through the plasma membrane in a reaction driven by its subsequent high affinity binding to cell surface heparan sulfate proteoglycans. This study concludes that Glypican-1 is the principal proteoglycan involved, possibly involving a unique tri-sulfated disaccharide binding site in close proximity to the cell surface. While the role of Glypican-1 appears unique to FGF2 rather than part of a generalized direct secretion mechanism, the observations highlight the complexity and significance of proteoglycan variation. The work is well done and generally convincing, but additional support for the authors' conclusion that a specific glycan structure in GPC1 is a specific ligand for FGF2 is required.

Evaluation Summary:
This paper is of interest for cell biologists and biophysicists that work on eukaryotic cell motility and the dynamics of the actin cytoskeleton. The authors combine a series of clever biological approaches to fuse small Dictyostelium cells together into 'giant cells' that make it much easier to spatially resolve actin wave dynamics with and without electrical stimulation when cultured on smooth or nano-textured surfaces. Sophisticated and methodical computational approaches are used to analyze these images and relate the data to actin polymerization and wave dynamics parameters using optic flow and associated techniques. This study is mostly descriptive, a full mechanistic explanation of the results remains open, but this compelling experimental system opens up possibilities for the field to analyze the molecular subtleties involved in these cytoskeletal reorganizations.

The paper details a thorough and careful analysis of an important hypothesis from the point of view of schizophrenia research: do muscarinic and dopaminergic receptors contribute to mismatch negativity effects? The answers could be useful for future treatment allocation in psychosis. The analysis was pre-registered and departures from the planned analysis were well-motivated and clearly described.

This paper presents a single-molecule, multi-color microscopy study of the real-time assembly of perfringolysin O, a member of the membrane attack complex perforin cholesterol-dependent cytolysin superfamily. With the ability to resolve different states of the species in the reaction, simultaneously with membrane leakage, this work informs on key aspects of the mechanism including identifying potential assemblies involved in membrane lysis, and how membrane binding, oligomerization, and pore transitioning depends on concentration and pH. While some additional controls are needed to clarify the interpretation of the results, this study will be of interest to many, including those studying cytolysin mechanisms, but also the broader field of single-molecule studies of membrane binding proteins.

Evaluation Summary:
In Drosophila neural progenitors (neuroblasts), sequentially-expressed transcription factors (known as temporal transcription factors) ensure the generation of various types of neurons and glia as they divide. However, the mechanisms regulating and finetuning the speed of temporal factor transitions has remained unclear and under-investigated. Here the authors concentrate on a specific temporal transition occurring in medulla neuroblasts and demonstrate that lineage-intrinsic Notch signaling facilitates this transition via at least two identified enhancers. This work provides important insights on the signals and mechanisms that promote temporal transitions in neural progenitors, and therefore regulate cellular diversity in the brain.

Evaluation Summary:
This manuscript is of broad interest for evolutionary biologists who seek to understand the dynamics of strongly advantageous mutations across time and space. It presents an elegant framework for inferring the strength of natural selection and spread of adaptive variants that accounts for spatially and temporal patterns of genetic variation. The authors extend a previously developed statistical inference method, performs some tests of the performance of their method on simulated data and apply the method to two well-known targets of selection. The development of the method is timely given the growing availability of ancient DNA collections, which have the power to largely increase the accuracy of selection inferences and parameter estimates.

Conway and colleagues use a combination of experiments and theory to test models for how kinetochore-fibers are born in mammalian spindles. Their work is consistent with a model where kinetochore-fibers primarily nucleate de novo at kinetochores, rather than arise from search-and-capture of microtubules. This work should be of interest to experimentalists and theorists broadly interested in self-organization, and in cell division.

Evaluation Summary:
In this manuscript by Kissiov et al. the authors show that enhancers can play an instructive role in controlling stable random monoallelic expression (RME). In order to do so, they initially focus on a limited set of natural killer (NK) receptor genes that are subject to RME, which they investigate using several in vivo genetic models. Furthermore, they also show that RME can be considerably more prevalent than previously thought and that enhancer strength and/or number might influence the extent of RME for different genes. One remaining question may be whether this model may apply to other gene types than hematopoietic-related genes. Overall, this is a highly relevant manuscript with major implications in gene regulation and enhancer biology and, thus, of broad scientific interest.

Evaluation Summary:
This theoretical study describes the interaction of a planar brush or film of the resident unstructured components of the nuclear pore complex (NPC) called nucleoporins (FG-nups) and different nuclear transport receptors (NTRs). The authors describe impacts of competitive binding that give rise to enrichment of the NTRs, NTF2 and importin-beta, at different depths of the FG-nup film, which could relate to experimental observations in other studies, as well as evidence that crowding could promote the rate of nuclear transport by modulating FG-NTR binding/unbinding. The conclusions were found to be generally supported by the data, relevant to the field of nuclear transport, and able to make specific predictions that can be experimentally tested in the future, although previous studies in the field and the novelty could be better described.

In this study, Tang and colleagues report that the deletion of the fructose-2,6-phosphatase TIGAR leads resistance to cold-induce hypothermia. Using different complementary approaches, they found that this phenotype originates from alteration in cholinergic neurons. In particular, they found that deleting TIGAR in ChAT-expressing neurons recapitulates the phenotype of the global knock-out. Overall, this is a well-performed study that provides evidence for a role of TIGAR in regulating the neuromuscular junction.

Evaluation Summary:
In this manuscript, the authors present at interesting strategy for directing simultaneous induction of both mesoderm-derived cardiac and endoderm-derived lung epithelial lineages from human induced pluripotent stem cells (hiPSC). All reviewers found the work to be of interest, but concerns were raised regarding the efficiency of the differentiation process (including % of differentiated cells in the final cultures) . In addition, it is noted that experiments presented are based on analysis of a single hiPSC cell line, and only part of the differentiation was repeated in another cell line, and thus the broader applicability of the presented protocol remains to be established. However, the interesting data support the conclusions presented. It is likely that the presented methods will be very useful for researchers focusing on heart and lung development, and may inspire others to take similar approaches for studying development of other organs.

Evaluation Summary:
The authors used phage display deep mutational scanning of SARS-CoV-2 Spike protein to profile antibody epitopes outside of the RBD that were recognized in two cohorts of subjects, which together included mRNA vaccinated, SARS-CoV-2 infected with mild or severe COVID-19 and vaccinated with prior infection. Key findings of the study are that severe COVID-19 and vaccinated individuals had higher binding to Spike protein regions NTD, CTD, and SH-H compared to individuals with mild COVID-19, while mild COVID-19 infections had higher binding to FP than vaccinated or severe COVID-19 individuals. They also reported that vaccinated individuals with or without prior infection were not different and that covariates did not appear to impact the antibody recognition profiles. The authors identified potential escape pathways in these epitope regions, some of which differed between vaccination and infection or drifted over time. The authors acknowledge that this approach is limited to linear epitopes and does not include RBD epitopes. However, the study provides novel insight into the major epitope regions targeted by polyclonal antibodies elicited by vaccination vs. infection, as well as potential pathways for the virus to escape recognition.

Evaluation Summary:
Karasawa and colleagues examine two gain-of-function mutations in NLRP3, which are known to cause cryopyrin-associated periodic syndromes (auto-inflammatory diseases with different manifestations), and demonstrate that both mutations appear to result in cryo-sensitive aggregated foci when expressed in cells. This is a very impactful and extensive body of work that is of broad interest to the fields of inflammasomes and autoinflammatory diseases. Data presented support the conclusions, and the findings are translational for patients and applicable to our general understanding of inflammasome function. However, specific issues raised by the Reviewers should be addressed.

This preclinical study reports on a novel strategy for sepsis. Sepsis induced by Group A Streptococcus (GAS) in mice leads to depletion of bone marrow HSPCs and mortality and infusion of naive donor HSPCs lower mortality but has no effect on bacterial burden. This supports that HSPCs infusion might attenuate the detrimental immune response in sepsis warranting further investigation of this novel concept.

Evaluation Summary:
Using a genome wide screen, the authors identify novel pathways that protect Pseudomonas aeruginosa against Type-6 secretion-mediated by other bacterial species. Importantly these pathways each protect against specific effectors. As an example, the authors further show that one factor Arc3B protects against phospholipase activity by antagonizing the production of lysophospholipids induced by phospholipase-type effectors. These findings uncover potentially conserved and unsuspected bacterial-defense pathways.

The identification of separate brain systems associated with learning from unexpected pain and learning from unexpected pain relief contributes to understanding of pain avoidance learning. The combination of behavioral data, neuroimaging and computational modeling provide support for many of the central claims of the paper, however weaknesses in the experimental design limit the support for the claims based on the results of the pharmacological manipulation.

Evaluation Summary:
This work describes how mitochondrial calcium in different regions of pyramidal neurons is controlled by action potentials and synaptic input. The authors show that calcium is controlled in a highly non-linear manner by calcium entry into cells (through voltage-dependent calcium channels) during sequences of action potentials. A particularly interesting finding is the high degree of localization of calcium rises in individual mitochondria in dendrites, and the requirement for both synaptic input and back-propagating action potentials to produce prominent rises of calcium in dendritic mitochondria. The work provides fundamental new information about how calcium entry during action potentials and synaptic input controls mitochondrial function.

Evaluation Summary:
RIF1 is a protein of the DNA damage response with key roles on genome integrity: it prevents DSB resection and hence accurate HR repair, whilst protecting stalled forks from degradation under replication stress conditions. The authors' main finding is the identification of 3 residues in RIF1 protein, that can be phosphorylated in ATM/ATR-dependent manner. However, this phosphorylation is dispensable for the ability of RIF1 to limit double-strand break resection, but is required to counteract the degradation of stalled replication intermediates mediated by the DNA2 nuclease. Therefore, the manuscript suggests that the three sites can provide a potential switch between the two functions of RIF1. These findings will spark the interest of readers working in the DNA replication and repair fields. However, the actual mechanism by which blocking RIF1 phosphorylation prevents RIF1 function at replication forks still needs to be determined.

Given the multiple papers characterizing interstitial cell types during mammalian cardiac injury response, this type of characterization in one of the leading regeneration model systems is overdue. The authors utilize single cell sequencing approaches to identify dynamics and key features of interstitial cell populations during zebrafish cardiac regeneration, which largely supports the claims of the paper. The data presented here have the potential to serve as a valuable reference resource for future studies, although some of the conclusions, in particular those on the function of tal1 and mmp14, are not yet sufficiently supported by data.

Evaluation Summary:
The possibility that local or systemic hypoxia regulates aspects of the immune system has attracted widespread interest over the last decade or more. Previous work has implicated regulatory T cells in at least some of these responses, and has demonstrated that over-activation of a specific hypoxia inducible factor (HIF) isoform, HIF-2alpha has the potential to driven pro-inflammatory lymphoproliferative responses characterized by defective regulatory T cells. The current work demonstrates that genetic activation of these hypoxia-signalling pathways that is restricted to the regulatory T cell lineage is sufficient to drive this type of immune activation. The work is important since it provides a focus for study of the mechanism, for which the authors make a proposal based on mis-localization of regulatory T cells. It is also important in focussing a key questions (requiring further study) as to whether physiological or pathological hypoxia, specifically affecting these cells, will drive such a response and/or whether the lymphoproliferative phenotype could be affected adversely or beneficially by agents that are being used to upregulate or downregulate hypoxia-signalling pathways in other settings.

This work, while rather qualitative, will nevertheless likely attract great interest from a diverse range of scientists working on multicellularity, the biophysics of cell packing, and geobiological problems.

This is a challenging study exploring the effects of a commonly used analgesic, remifentanil, on brain and spinal cord related pain processing in humans. It is of considerable interest to the pain research, neuroimaging and opioid neuroscience communities and are also relevant to clinicians who commonly use opioid infusions. The authors have used sophisticated methods for combined brain and spinal cord functional magnetic resonance imaging to examine the influence of an intravenous opioid on pain processing in the ascending and descending pain pathways in healthy subjects. The authors have conducted a comprehensive assessment in large numbers of subjects and have explored both changes in amplitude of activity as well as connectivity. Their detailed analysis strengthens findings from previous human and animal studies and extend to demonstrate novel changes in connectivity in the descending pathway to the spinal cord although these data are potentially compatible with alternative interpretations and may need to be reinforced by further analysis.

Their findings shed light on why biological collision detection circuits may have converged on particular solutions.

The work evaluates the production of P. falciparum sexual stage parasites in blood samples from asymptomatic parasite carriers through the dry season and symptomatic malaria patients in the wet season. Sexual stage parasites are required for malaria transmission via mosquito, but historically their low levels in peripheral blood have limited analysis. The work here monitored asexual and sexual stage parasitemia and found that the relative expression of early gametocyte genes, including ap2-g, is similar in samples from asymptomatic and asymptotic individuals. The data was used to model gametocyte availability from the initial symptomatic infection through the chronic phase and advances the understanding of factors that contribute to malaria transmission.

In this paper, Sahinyan and colleagues developed a method for analyzing chromatin accessibility in single murine myofibers. This goal was achieved by adapting the previously published OMNI-ATAC protocol to the specific properties of the myofiber environment. To demonstrate the validity of this method, they isolated myofibers from uninjured and regenerating murine EDL muscles dissected from wild type animals. In a second experiment, this method was applied to isolate myofibers from mdx mice, a model of Duchenne Muscular Dystrophy. The resulting datasets were further compared to the one generated from purified muscle stem cells.

In their manuscript, Lu et al. use a combination of experimental approaches to determine how cellular components are transported from nurse cells into the growing oocyte during Drosophila egg development. The authors demonstrate that the minus-end directed microtubule motor, dynein, generates cortical flow by gliding microtubules along the cell cortex. This flow is capable of propelling cargoes through the ring canals into the growing oocyte via a bulk cytoplasmic transport mechanism. This action is distinct from dynein's cargo transport functions, as the authors are able to replace dynein with a minus-end directed kinesin linked to the cortex and observe the same phenomenon. Overall, this work had broad significance to cell biologists and developmental biologists interested in intracellular transport functions and oocyte development.

Evaluation Summary:<br> This work elegantly fuses cryo-EM, x-ray crystallography, and in vitro transport experiments to describe the structural basis for functional diversity in the SLC11/NRAMP family of membrane transporters. This work identifies factors responsible for selectivity of classical NRAMPS for transition metal ions (Fe, Mn) and the NRMT clade for alkali metal ion (Mg). Although selectivity is much discussed in transport of divalent metal ions, this is an outstanding example of a study that gets to the bottom of the structural determinants governing this behavior.

The regulation of cell growth is crucial for our understanding of how cells control their size as well as how they balance cell mass and volume. While recent studies carefully measured single cell mass trajectories during the cell cycle, revealing complex growth patterns, the volume growth patterns of animal cells are poorly understood. In this interesting study, Cadart et al. now present high-precision measurements of 1700 HeLa cell growth trajectories and offering evidence for the mechanisms that regulate volume growth-rate fluctuations. This is an important demonstration of cell autonomous volume regulation.

Evaluation Summary:
Nowicka et al., evaluated radiation dose and time dependent changes in the levels of selected serum miRNAs in human patients who received partial or complete myeloablative total body irradiation (TBI) and propose a panel of circulating miRNAs as potential radiation biodoismeters. The team employed next generation sequencing approach for discovery (or rediscovery) and quantification of selected responders by qRT-PCR using non-responsive miRNAs purified from exosomes in serum for evaluation of relative changes. Excellent bioinformatics and bio statistical methods are employed. However, critical biomarkers they propose as radiation biodosimeters have already been identified and published earlier. There is little novelty here and the translational significance of the study is moderate.

Circadian disruption is widespread in our modern 24/7 society, leading to an increased prevalence of common diseases including type 2 diabetes. The authors conducted an unbiased screen for small-molecule compounds that can restore the attenuated insulin secretion from pancreatic beta cells caused by a disrupted circadian clock. They identified ivermectin and its clock-controlled target, the P2Y1 receptor, which regulate glucose-stimulated Ca2+ influx and insulin secretion in beta cells.

This paper will be of interest to the large class of neuroscientists who investigate brain plasticity. It identifies short-term plasticity in a subcortical region, the ventral division of the pulvinar, following monocular deprivation in adult humans. The work is believed to extend our research focus on the topic of ocular dominance plasticity from mainly the cortex to a larger brain network including the subcortical stages of visual processing. This is an intriguing possibility, but further evidence is required to fully support the claims.

The overarching goal of this study was to identify eco-evolutionary feedbacks between plant community diversity and global change drivers. The authors aimed to test the hypothesis that a decline in species richness due to various global change drivers selects for traits that will make species more vulnerable to the further effects of these drivers, amplifying thus the initial diversity decline. This research is of prime importance to botanists, plant ecologists and ecosystem ecologists wanting to understand the effects of global change on plant diversity and productivity.

It is potentially a major advance for the field. They leveraged crystallography to understand the mechanism by which the ligands enhance fluorescence, then characterized top sensors for sensitivity, selectivity, and kinetics, and their utility in plasma membrane and ER sensing in neurons and cell lines. The tools developed by this team will enable investigators to track nicotinic receptor partial agonists in different subcellular compartments with relatively fast time resolution.

This paper is of interest to cell biologists, biochemists and biophysicists interested in how adhesion and signaling proteins at the cell surface help cells (and especially neurons) interact and perform self/non-self-recognition and self-avoidance. The authors provide the first extensive biophysical dataset examining a large subset of potential trans (across two cells) and cis (on the surface of the same cell) interactions between different isoforms of the ~60 clustered protocadherins (cPcdhs). There data show that all tested trans interactions are strictly homophilic and that not all possible cis interactions are equivalent. These results provide additional layers of complexity and constraints on how this protein family can provide neurons with the ability to perform self-recognition and self-avoidance.

This paper will be of interest to the lipid metabolism and transporter communities. Fatty acids that are too long to be transported into mitochondria are instead transported into peroxisomes for their break down i.e., beta-oxidation. The authors have determined the cryo-EM structure of human ABC transporter ABCD1 (ALDP), which translocates very-long-chain fatty acids (VLCFA) conjugated to coenzyme A across peroxisomal membranes, in complex with its substrate. While the work is well done, it is unclear what new mechanistic insights are gained from the ALDP structure. Also, the proposed conformational differences based on AlphaFold models should be taken with caution.

The authors provide a series of well-executed and designed high-resolution sequencing data demonstrating that transcription factor (TF) binding perturbs alkylation base damage formation as well as inhibits its repair via base excision repair (BER) at TF binding sites. Moreover, they demonstrate differences between nucleotide excision repair and BER at TF binding sites that are consistent with the different repair mechanism of these two pathways. These results should have an important and timely impact on the field.

Evaluation Summary:
The study reports the development of high-throughput droplet digital PCR to detect Plasmodium falciparum parasites carrying pfhrp2 and pfhrp3 gene deletions. These mutations usually cause false-negative RDT results on malaria tests. Although there are several PCR-based detection methods already available, the assay is useful as an alternative, particularly in countries and settings where droplet digital PCR is routinely used. The strength lies in its capability to detect hrp2 and hrp3 deletions in samples with multiclonal (more than one clone) infections. This has the potential to assist in surveillance for pfhrp2/3 deletions programs where RDTs designed to detect HRP2 are the primary test leading to false negative results, particularly in medium to high transmission settings. The study will be of interest to those studying infectious diseases.

Are enzymes found in organisms that optimally grow at colder temperatures are more active than the same enzymes found in organisms that optimally grow at warmer temperatures? Here, an assessment of the catalytic constants for approximately 2200 enzymes (obtained from the BRENDA database) showed no correlation between the relative catalytic activity and the optimum growth temperature. Further support for this conclusion was obtained from the measurement of the catalytic constant from a selection of ketosteroid isomerases from organisms that optimally grow between 15 and 46 degrees centigrade. These are interesting results, although the significance with respect to earlier studies has not been clearly explained.

This paper addresses the question of why invertebrates use innexins and vertebrates connexins to form gap junctions. The authors survey genomic data across animal diversity to search for innexins and connexins and analyse the distribution of glycosylation sites in the extracellular loops of these proteins. The reported data support the hypothesis that connexins replaced innexins in chordate gap junctions due to an evolutionary bottle neck. Overall, the data were properly analyzed, but could be improved with respect to the sequence data for some phyla and the discussion from the results obtained.

This article provides insight into how Astyanax mexicanus cavefish may have adapted to the hypoxic waters present in the cave environment. How the extreme environmental pressure of low oxygen has shaped cavefish evolution has been understudied compared to other pressures like absence of light or low nutrients. This is the first study to look for changes in early cavefish development that may provide hypoxia tolerance. The claims that cavefish have expanded erythrocyte development and increased hypoxia gene expression are strongly supported by the data. Demonstrating that these traits are adaptive and provide hypoxia tolerance requires further assessment of the current results and would be strengthened by additional experiments. Overall, this work is an important first step in understanding the evolution of hypoxia tolerance in A. mexicanus cavefish.

Evaluation Summary:
Using data from the 1970 British Birth Cohort study, the authors demonstrated the utility of Generalized Additive Models for Location, Scale and Shape (GAMLSS) to investigate the association of three risk factors (sex, socioeconomic circumstances, and physical inactivity) with body mass index and mental wellbeing. This work provides empirical evidence for why we should consider how risk factors influence the variability and not just the mean of outcomes. From the perspective of developing personalized medicine, it is important to know whether interventions have response heterogeneity as the first step. If such heterogeneity is identified, the next step will be to identify the factors associated with the heterogeneity (or those who will be benefitted from the intervention). Therefore, this study contributes to the first step by investigating the possibility of response heterogeneity.

Evaluation Summary:
This manuscript addresses important questions: what is the relationship between circadian and homeostatic regulation of sleep, and how do the circuits underlying these levels of control interact? The authors have designed a very elegant method to answer these questions in Drosophila: a new sleep-deprivation protocol that allows them to test sleep rebound over the course of the day. Interesting observations are made, such as time-of-day dependence of sleep homeostasis, identification of important neural pathways modulating sleep rebound in a time-dependent manner, and molecular and physiological variations that might drive time-dependent sleep homeostasis. Experiments establishing a link between the circadian clock/neurons and molecular and physiological changes observed in sleep homeostat neurons would help to provide support for the claims made in the title and abstract.

Evaluation Summary:
This study addresses a major missing element in the understanding of how bacteria grow their cell wall and the role of lytic transglycosylases in this process. It had been previously assumed these enzymes cut glycan strands to make room for the insertion of new glycans. However, results presented in this manuscript demonstrate these enzymes have a very different, yet essential role in degrading uncrosslinked glycan strands in the periplasm. The authors further demonstrate that in the absence of lytic transglycosylases, cells undergo periplasmic stress due a toxic accumulation of these "free strands" in the periplasm. The work will be of interest to those in the bacterial growth and division field.

This paper is of broad interest to readers interested in motile cilia and cargo transport mediated by intraflagellar transport (IFT). It examines how radial spokes are trafficked into cilia by IFT, which represents a key process in the assembly of motile cilia. The authors demonstrate that an adaptor protein (ARMC2) is needed for association of radial spokes with the IFT machinery. They also find that the interaction of ARMC2/radial spokes with individual IFT trains (or particles) occurs in a stochastic manner rather than there being a specialized subset of trains specifically designated for a particular cargo. The results support the key claims in the paper.

This study is of interest to the broader audience of cell biologists, as it aims to dissect the hierarchy of protein recruitment and lipid conversion events that may provide a potential mechanism for the formation, maturation and fate of macropinosomes. The conclusions are based on the observation that pharmacological inhibition of the lipid kinase VPS34, which generates the signalling lipid PI3P on endosomes, prevents accumulation of Rab5 on macropinosomes, blocking their maturation and causing them to re-fuse with the plasma membrane.

By comparing this structure to those of other cyanobacteria that contain red forms, the authors aim to identify the chlorophylls responsible for low-energy absorption in PSI. Their second aim is to understand the role of the red forms. The topic is interesting, the structural data are very good, but the conclusions regarding the role of the red forms are not supported by data.

The current manuscript will be of interest to researchers working in aging, diabetes, and neurocognition. This work emphasizes the role of diabetes in brain aging and cognitive functions that are considered an hourly need due to the increasing trend in the prevalence of diabetes around the world. This article provides valuable information about specific brain regions altered during aging and diabetes. Further, this article reports how T2DM accelerates the aging-associated decline in cognition and brain function. Extensive analysis of human datasets and comparison with published data from other researchers support the conclusion of this study. However, as mentioned by the authors, certain decisions like diabetic interventions that do not rescue brain damage need further validation.

Mika and colleagues reconstruct the evolution of uterine endometrial transcriptomes during pregnancy from 23 diverse species of mammals that differ with respect to their degree of placental invasiveness. Through this analysis the authors infer that the eutherian mammal ancestor had an invasive mode of placentation and that the degree of invasiveness of placentation is reflected on uterine endometrial gene expression during pregnancy. Thus, phylogenetic analysis of gene expression profiles of different mammals groups them on the basis of degree of placental invasiveness, a quite striking finding.

Evaluation Summary:
Diminishing returns on sampling new variable sites with increasing samples sizes is a classic limitation of population genomics and one that limits the power of population genomic approaches to make site-specific inferences of natural selection. This timely study demonstrates that methylated CpG sites, which have a mutation rate an order of magnitude higher than other sites in the genome, are saturated with polymorphisms in modern human genomic datasets. They can thus serve as a starting point for understanding the effects of natural selection at the resolution of single nucleotide sites. The manuscript is a clearly written presentation of the state of the field and the claims are supported by a variety of thoughtful analyses. Additional work will be needed to take full advantage of the insights from this study.

Many questions remain as to how humans control and eliminate T. gondii following infection. In this manuscript, Rinkenberger et al. reveal a previously unidentified and understudied host factor, RARRES3 that promotes cell autonomous control of T. gondii in human cells. The precise mechanism of control and its in vivo relevance remain areas for additional work.

The paper by Rai and colleagues examines the transcriptional response of Candida glabrata, a common human fungal pathogen, during interaction with macrophages. They use RNA PolII profiling to identify not just the total transcripts but instead focus on the actively transcribing genes. By examining the profile over time, they identify particular transcripts that are enriched at each time point, building a hierarchical model for how a transcription factor, CgXbp1, may regulate part of this response. While the authors have generated a large and potentially impactful dataset, along with several interesting observations, it is important to be cautious as the direct targets of CgXbp1 were characterized under one particular condition and the transcriptional analyses were obtained in another condition, one shown to be highly dynamic as during macrophage infection.

Kunze et al. provide a fine experiment to show that both increases in mean temperature and (extreme) variability in temperature regimes have important consequences in host-pathogen interactions. The results presented in this manuscript shed a light on why disease spread models fed by experimental data (commonly obtained in stable environmental conditions) are frequently inaccurate. These results lead us to more realistic understanding of the impacts of climate change in biological species but also identify the need of mechanisms behind species interaction in fluctuating environments/temperatures. This manuscript thus comes timely as the planet is warming, and disease ecologists, limnologists, epidemiologists and physiologists are interested in the consequences.

This finding has important implications for the clinical application of DNA-PK-targeted inhibitors. The data are of high quality and derive from two independent cell lines, genetic requirements were mostly established by gene knockouts, and the latest genome-wide sequencing techniques were applied to measure resection tracts. The key claims of the manuscript are supported by the data presented by the authors; however, further validations are needed to strengthen the quality and impact of the paper.

Homeostatic plasticity helps to confine neural network activity within limits. In this study, the authors show that loss of PAR bZIP family of transcription factors leads to overcompensation of excitatory synaptic transmission and average network activity upon sustained activity deprivation. The work identifies an endogenous transcriptional program that constrains upward homeostatic response and whose activity is implicated in preventing aberrant network activity associated with epilepsy and other brain disorders. These are exciting results that address the question of broad importance. While most arguments are supported by data of high quality, further experiments would strengthen the claims about the relative contribution of excitatory and inhibitory mechanisms and clarify the nature of compensation.

This manuscript investigates the cellular role of the juxtamembrane region in the EGF receptor, a poorly understood portion of the EGFR cytosolic domain that connects the transmembrane segment to the kinase domain. Through a series of well-designed experiments, the work shows that the endocytic trafficking route of EGFR following its activation is determined by the juxtamembrane coiled-coil conformation in a model cell line. This finding is important for three reasons. It identifies a critical role for the juxtamembrane region; it resolves the discrepancy that TGF-beta dissociation from EGFR is supposed to occur at higher pH, yet the EGFR-TGF-beta complex continues to signal from endosomes; and it pinpoints the mechanism of EGFR inhibition by a new class of tyrosine kinase inhibitors.

Multiple inherited mutations in the epithelial CFTR anion-permeable channel cause cystic fibrosis through different molecular mechanisms that can be targeted by different types of drugs to treat the disease. Drawing from available structural information and double-mutant cycle analysis of patch-clamp recordings, Simon and Csanády find that one of the most common CFTR disease-causing mutations, R117H, disrupts an interaction between the R117 side-chain and a main-chain carbonyl that selectively stabilizes the open state of the channel. These findings may open new paths of exploration for treating patients carrying this mutation, and provide important mechanistic constraints towards understanding the gating mechanism of CFTR proteins.

The paper describes single-molecule experiments that address the assembly of a double hexamer of the Mcm2-7 complex that is required to license all origins of DNA replication in eukaryotic cells by formation of a pre-Replicative Complex (pre-RC). The observations show that one Origin Recognition Complex, an ATP-dependent DNA binding protein, can load both Mcm2-7 hexamers in opposite orientation. The results nicely complement prior data on the mechanism of pre-RC assembly.

Evaluation Summary:
This manuscript focusses on a little studied, but highly interesting presumptive mechanosensory cell type in cnidarians, the 'hair cell'. The work shows that the POU-IV transcription factor is required for the maturation of this cell type in the sea anemone Nematostella vectensis. Because POU-IV transcription factors also play essential roles in the differentiation of mechanoreceptors in many bilaterian phyla, this suggests an evolutionarily ancient role of POU-IV in regulating mechanosensory identity. This study will hence be of great interest to developmental biologists and evolutionary biologists who are interested in the developmental evolution of neuronal cell types.

Evaluation Summary:
Kröger et al use 2-photon FLIM tomography to perform correlative imaging on in vitro, ex vivo and in vivo blood and skin cells to determine characteristic NADPH fluorescence lifetimes for M1 and M2 ends of macrophage spectrum. Interestingly, M1 and M2 macrophages, and all other tissue cells, had distinctive lifetime features leading to robust prediction of phenotypes, with ground trust defined by cytokine staining. They generate a decision tree that has ~90% accuracy in identifying M1 and M2 based on FLIM parameters and additional information. The ability to use two photon fluorescence lifetime tomography of NADPH fluorescence to identify macrophages and their inflammatory status in human tissues should open opportunities in experimental medicine and eventually medical diagnosis.

Evaluation Summary:
Cholesterol has long been known to have significant effects on G protein-coupled receptor (GPCR) ligand binding properties and stability, and cholesterol/GPCR interactions have frequently been observed in high-resolution structures. However, relatively limited biophysical work has been done to investigate the mechanistic basis for cholesterol's effects. This manuscript describes the use of a sensitive 19F NMR probe to monitor conformational equilibria in a prototypical GPCR, the A2a adenosine receptor. These experiments, together with data from other NMR experiments, computational analysis, and G protein assays, show that the subtle effects of cholesterol derive in large part from modulation of membrane biophysical properties, in contrast to conventional allosteric modulators that exert their effects through direct long-lived receptor binding.

Evaluation Summary:
This manuscript is of broad interest to developmental biologists and those studying transcriptional/epigenetic regulation of cell-specific and housekeeping gene programs. The work demonstrates that Polycomb complexes coordinate the regulation of distinct groups of genes during early embryogenesis, which offers interesting insights into how very early embryos differentially control housekeeping versus specific developmental gene promoters/enhancers. The data are of high quality, and the conclusions are insightful yet measured.

Evaluation Summary:
Mejias and Wang propose here the first large-scale model of the brain that actually performs a cognitive task. Previous models have focused on neural dynamics during the so-called "resting state", in which subjects are not performing any cognitive task - thus, resting. This study is therefore an important improvement in the field of large-scale modelling and will certainly become an influential reference for future modelling efforts.

Evaluation Summary:
Kluger and colleagues investigated the influence of respiration on visual sensory perception in a near-threshold task and argue that the detected correlation between respiration phase and detection precision is liked to alpha power, which in turn is modulated by the phase of respiration. The main finding - that the moment-to-moment relationship between excitability and perception is coupled to the body's slower respiratory oscillation - poses a potentially important advance for advancing our understanding of how the brain-body system works as a whole.

Evaluation Summary:
This paper is of outstanding interest to the broad community of scientists interested in biological energy conversion in general and rotary ATPases in particular. The authors show that the 36{degree sign} power stroke in ATP synthesis is subdivided into two steps of 11{degree sign} and 25{degree sign} in the E. coli enzyme, which serves as a comparatively simple model of the fundamental and universally important process of ATP production in mitochondria and chloroplasts. By combining precise and sophisticated single-molecule studies with directed mutagenesis, this work provides the much-needed functional context for recent high-resolution cryo-EM structures of rotary ATPases.

Evaluation Summary:
Campylobacter jejuni is serious food-borne pathogen and understanding how the various products necessary for pathogenesis are regulated is a key step in preventing its growth and/or treating disease. Here, Sharma and coworkers describe the complex pathway that leads to the maturation of two complementary regulatory RNAs and how one of the RNAs antagonizes the other to relieve repression of a virulence-related gene.

Evaluation Summary:
In this study, the authors develop a model to understand the simplest form of collective migration represented by a pair of cardiopharyngeal progenitor cells. They propose that the collective migrates as a "supracell", with leader cells assuming a greater protrusive capability and trailer cells assuming greater retractive capability. They meticulously study the effects of leader-trailer and cell-matrix adhesivity, intracellular force distributions and noise on robustness of cell migration. They corroborate their simulation results with experiments. Overall, this study comprehensively demonstrates that migrating as a collective leads to more mechanically efficient and persistent migration than as a single motile cell.

Evaluation Summary:
This work identifies the primary genetic mechanism underlying UV-absorbance variation across the geographic range of sunflower (Helianthus annuus) and provides evidence that suggests that abiotic variables, rather than pollinators, may maintain this variation in H. annuus and perhaps Helianthus broadly. While claims about direct links to fitness in natural population remain untested, the authors synthesize an ambitious amount of work from an impressive breadth of methods (from transgenics to ecology) that will be of high interest to ecologists and evolutionary biologists.

Evaluation Summary:
This manuscript by Jayaram and colleagues uses computational modeling approaches to examine how temporal filtering of an odor signal contributes to navigation success in different odor environments. The manuscript advances the literature in considering how different algorithms may be optimal for different environments. Further evidence is required to more convincingly prove the intriguing trade-off between frequency and "intermittency" sensing described here.

Evaluation Summary:
This contribution is of interest to molecular phylogeny scientists in particular and to a broad public interested in early evolution in general, as it confirms the long-standing (but recently challenged) assumption that bacteria and archaea are separated by a long branch. It elegantly rebuts a recent study claiming that one of the common markers used for molecular evolution, ribosomal proteins, are actually ill-suited for deep phylogenies and that archaea and bacteria are much closer to each other than previously thought.

Evaluation Summary:
The authors show that a widely arborizing inhibitory interneuron AL reduces the variability of olfactory responses in at Drosophila Kenyon postsynapses in the mushroom body calyx, which receive inputs from the projection neurons (PNs) in the antennal lobe. The data support a model in which APL neurons, which also receive inputs from PNs, mediate scaled GABAergic feedback to normalize of postsynaptic responses in the calyx. The conclusions, based on detailed analysis of one odorant are mostly well supported by the data.

Evaluation Summary:
Ribosomal proteins are prone to aggregation. This work provides strong experimental support for a novel mechanism by which the level of the mRNA encoding two different ribosomal proteins is fine-tuned by variation in the abundance or availability of their chaperones. This regulation is proposed to operate through mRNA degradation at the translating ribosome. The data are extensive - from genetic observations that hint at the existence of a feedback loop, through interaction mechanisms, to biological significance. The logical links between the different steps in the analysis are clear, sound and well set out. The conclusions are unanticipated, but convincingly supported and very likely relevant and important for other systems beyond yeast.

This study gives us information about the potential of the endocannabinoid system to become a novel target for the treatment of Williams-Beuren syndrome. The authors found there is an alteration of brain cannabinoid type-1 receptor (CB1R) in a mouse model of Williams-Beuren syndrome (CD mice). Modulation of CB1R by JZL184 treatment improved social and cognitive phenotypes and also cardiac function of CD mice. This study will be of great interest to researchers and clinicians in the field of genetic diseases.
