     Evaluation Summary:

     Information about the environment obtained through sensory organs is processed and utilized at multiple levels in the brain. In this study, the authors use a variety of modern genetic and optophysiological tools to uncover the function and connectivity of glutamatergic neurons in a higher brain center of Drosophila - the lateral horn. They find that these neurons do not only encode chemical odor identity, but also the hedonic value (attractive or repulsive) of odors. This advances our understanding of how odors are represented in the brain will be of value to those who are interested in odour coding and behavioural valence of various odours.

     Evaluation Summary:

     This manuscript describes a useful dataset for those interested in regulatory variation. The large scale of variants surveyed offers the potential to look for dependencies between nearby TF binding events at the same accessible site, and will likely be useful to those interested in dissecting sequence determinants of transcription-factor binding genome-wide.

     Evaluation Summary:

     The strength of this paper is identifying a novel factor Bach2 that might be involved in the generation and/or maintenance of NK cells. To date, the full molecular network guiding the development, maturation and maintenance of NK cells has not been fully defined and Bach2 has not yet been investigated.

     Evaluation Summary:

     Stolyarova et al. investigate a highly polymorphic species, the fungus Schizophyllum commune, finding that compared to synonymous mutations, levels of linkage disequilibrium between nonsynonymous mutations are higher within genes than between genes. The authors propose this observation may be explained by compensatory interactions between nonsynonymous alleles, pointing to the presence of positive epistasis. This paper should be of interest to population geneticists and evolutionary biologists studying the role of natural selection.

     Evaluation Summary:

     The manuscript by Liu et al., aims to develop a novel MRI-based approach to monitor virus specific CD8+ T cells and their relationship to cerebrovascular pathology in living brains. Using a mouse model of VSV brain infection, they show that MRI approaches can be used to identify microbleeds in the brain, and these microbleeds occur independent of immune cell influx. Furthermore, the transfer of low numbers of virus specific CD8+ T cells can reduce cerebrovascular bleeding. The capacity to track virus specific T cells and cerebrovascular pathology in real time in living brains would be a major technological advance.

     Evaluation Summary:

     Peyregne et al. studied the genes encoding proteins of the spindle apparatus. These genes have an elevated number of nonsynonymous substitutions in modern humans, and by comparison of modern and archaic alleles the authors identify that some Neanderthals had already the modern human haplotype at the KNL1 gene, raising the possibility that Neanderthals acquired it from modern humans. This study will be of interest to evolutionary biologists and anthropologists, because it supports the hypothesis that modern humans and Neanderthals interacted more than once in the past.

     Evaluation Summary:

     The primary audience that will be keenly interested in these findings will be those with an interest in T cell development and thymic function, however given the broad applicability of transendothelial migration, there will also likely be broader interest in these findings. The manuscript provides key new insight into the importation of hematopoietic progenitors into the thymus to initiate T cell development. Overall, the main claims of the paper are well supported by the studies presented, although some clarification is needed regarding some experimental details, in particular the thymus reconstitution model used to test the effects of CD47-SIRPa inhibition in immunotherapy.

     Evaluation Summary:

     By addressing shortcomings in rabies viral-mediated labeling of monosynaptic inputs to ventral tegmental area dopamine neurons, this study provides a previously unattained precision local inputs to VTA dopamine neurons. Main findings include the preservation of a medial to lateral topography in the projection patterns within VTA microcircuitry, prominence of inhibition of DA neurons from the substantial nigra pars reticulata (SNr), DA-DA transmission, and inputs from raphe serotonin neurons. The precise local VTA connectivity described here is important for identifying how dopamine neurons compute reward, prediction, and movement-related signals during behavior, and thus is likely to be of interest to neuroscientists interest in those processes and the midbrain dopamine system.

     Evaluation Summary:

     Pseudomonas aeruginosa regulates the production of many cooperative traits through quorum sensing cell-cell signaling. The authors carried out transcriptomic studies of experimental evolved populations of P. aeruginosa and observed that the size of the quorum sensing regulon decreases when only a few but not all the cooperative processes regulated quorum sensing are required for growth. Their findings are consistent with the hypothesis that quorum sensing regulated genes can be counter selected rapidly when not beneficial. This study is of interest for microbiologists studying quorum-sensing, and evolutionary biologists studying the evolution of cooperative behavior.

      Evaluation Summary:

      This study reports the phenotype of a zebrafish banp mutant that was identified in a screen for eye defects. Banp is known to regulate the transcription of a number of genes including those important in oncogenesis. In vivo function of Banp, especially in the context of normal development, remains to be better understood. The current study fills this knowledge gap and identifies the roles of banp during replication stress responses and mitosis. With somewhat more careful interpretation of the data and a clearer presentation of the results and their potential impact, this study will be of interest to scientists studying development, DNA damage responses and apoptosis.
