  This study provides useful insights into the ways in which germinal center B cell metabolism, particularly lipid metabolism, affects cellular responses. The authors use sophisticated mouse models to convincingly demonstrate that ether lipids are relevant for B cell homeostasis and efficient humoral responses. The authors then conducted in vivo as well as in vitro experiments, thereby strengthening their conclusions.

  This useful study describes a mechanism of microbial modulation of anti-tumor immunity, which is of considerable interest in the field. However, the experimental supports for the key mechanistic claim, the interaction between RadD and NKp46, are not robust. Multiple experimental inconsistencies, especially in vivo, weaken the conclusions, making the strength of evidence incomplete. Additional controls, direct binding assays, and clarification of in vivo mechanistic relevance would strengthen the work.

  This work provides one of the first important attempts to look at Drosophila immune responses against bacterial, viral, and fungal pathogens in a way that combines the roles of four major arms in immunity (Imd signaling, Toll signaling, phagocytosis, and melanization) rather than studying them separately. The findings are compelling and the tools provided can be used as they are, or built upon, in various contexts.

  This manuscript advances the prior finding that antigen recognition in the skill helps establish skin resident memory in CD8 T cells by elucidating the role of TGFBR3 in regulating CD8+ TRM skin persistence upon topical antigen exposure. Key novelty of the your work lies in generation and use of the CD8+ T cell-specific TGFBR3 knockout model, which allows them to demonstrate the role of TGFBR3 in fine tuning the degree of CD8+ T cell skin persistence and that TGFBR3 expression is promoted by CD8+ TRM encountering their cognate antigen upon initial skin entry. This is an important finding and is supported by convincing evidence. There are concerns about the use of FTY720 and the need to establish active TGFbeta limiting conditions to further test this working model.

  This important study presents the development of a novel inhibitor for SARS-CoV-2 Mac1 that has potential utility both as an antiviral therapeutic and as a tool for probing the molecular mechanisms by which infection-induced ADP-ribosylation triggers robust host antiviral responses. Though minor gaps in understanding the compound's precise molecular mechanism of action and its ability to target Mac1 from other coronaviruses remain, the evidence for its effects on SARS-CoV-2 in relevant biological models is compelling.

  This study reanalyzed previously published scRNA-seq and TCR-seq data to examine the proportion and characteristics of dual-TCR-expressing Treg cells in mice, presenting some useful insights into TCR diversity and immune regulation. However, the evidence is incomplete, particularly with respect to data interpretation, statistical rigor, and the functionality of dual -TCR Treg cells. The study is potentially of interest to immunologists studying T-cell biology.
