  This valuable study describes an interesting infection phenotype that differs between adult male and female zebrafish. The authors present data indicating that male-biased expression of Cyp17a2 mediates viral infection through STING and USP8 activity regulation. The authors present solid evidence linking this factor to direct and indirect antiviral outcomes through ubiquitination pathways. These findings raise interesting questions about immune mechanisms that underlie sex dimorphism and the selective pressures that might shape it.

  The findings of this study are valuable as it demonstrates that when treatment is initiated during acute infection, HIV specific CD8 T cell responses are maintained long term and continued proliferative capacity of these cells may play a role in reducing HIV DNA levels. The evidence supporting the conclusions are solid with rigorous and advanced methodology used with the major limitations being that the findings are association level and do not meet strict criteria for causality. The work is of interest to the HIV cure field and suggests that enhancing early HIV specific CD8 T cell responses should be considered in the design of interventional cure strategies.

  The authors investigated the epigenetic mechanisms regulating the differentiation of circulating monocytes that infiltrate the CNS and adopt microglia-like characteristics. The work is useful to the field, as the contribution of circulating myeloid cell-derived microglia remains controversial. However, the evidence presented is inadequate as the analyses are based on a very limited set of genes, which does not sufficiently support the authors' central claims.

  This timely and fundamental study introduces a human iPSC-based co-culture system that models Kupffer cell-hepatocyte interactions and aims to recapitulate liver-specific immune-parenchymal dynamics. Direct contact between iMacs and iHeps promotes mutual tissue-specific maturation, with iHeps downregulating fetal genes while iMacs acquire a Kupffer cell-like profile. This convincing in vitro model holds significant promise and is a leap forward; future experimental understanding will enhance its translational impact.

  This study provides valuable insights into the role of the NF-kB and IKK signaling pathways in γδ T cell development and survival, using robust genetic mouse models. While the research is methodologically sound, some conclusions require further evidence, with incomplete analyses, particularly regarding cell-intrinsic effects and mechanistic details. Overall, the findings are significant for immunologists interested in innate-like T cell biology and advancing the understanding of γδ T cell differentiation and maintenance.

  The study provides important mechanistic insight into the transcriptional control of γδT17 development, elegantly demonstrating how HEB and Id3 act sequentially and cooperatively to regulate γδT17 cell specification and maturation. The study provides compelling evidence that advances the understanding of E-Id protein dynamics in thymic T cell specification. The work is comprehensive, technically rigorous, and conceptually clear, and will be of interest to immunologists, developmental biologists, and those studying the molecular underpinnings of physiological outcomes.
