  This study provides useful insights into the subcellular localization, interaction with integrins, and functional importance of the cell surface receptor Piezo1 in migrating human T-cells. Whether Piezo1 is critically sensing mechano-physical cues during T-cell migration is however not well supported by direct experimental evidence. The data collected is solid otherwise.

  In this valuable contribution, the authors demonstrate that the infusion of NAD+ may prevent death and reduce disease severity from lethal experimental bacterial sepsis, possibly through inflammasome inhibition, without reducing bacterial load. They provide solid evidence for these protective effects of NAD+, though the precise mechanisms involved remain unclear and need further support and elucidation. The core findings may well have clinical implications but, in addition to mechanistic clarifications, contextualised interpretation as metabolic adaptation to sepsis would create wider interest.

  This is an important and interesting account of the ability of Ym1 crystals to promote type 2 immunity in vivo, in mice. The data presented are compelling, building on and significantly advancing evidence this group has previously published on the type 2 immunogenicity of other protein crystals. The work will be of relevant interest to immunologists and researchers working on type 2 inflammatory disease, in the lung and in others tissues.

  The study has added value to what we have already known in the potential pharmacological immunomodulatory therapies in LPS-induced sepsis, and especially the use of oral leucine might be of great interest to the readers engaged in this field. We believe this study is important and provides solid evidence on the potential use of leucine in sepsis.

  This study elucidates the role of a specific hemocyte subpopulation in oxidative damage response by establishing connections between DNA damage response and the JNK-JAK/STAT axis to regulate energy metabolism. The identification of this distinct hemocyte subpopulation through single-cell RNA sequencing analysis and the finding of hemocytes that respond to oxidative stress are important. The method for single-cell RNA sequencing and related analyses are convincing and experiments linking oxidative stress to DNA damage and energy expenditure are solid. The finding of stress-responsive immune cells capable of influencing whole-body metabolism adds insights for cell biologists and developmental biologists in the fields of immunology and metabolism.

  This is an important study that investigates the role of commensal microbes and molecules in the antigen presentation pathway affecting the development and phenotype of an unusual population of T lymphocytes. The authors provide compelling evidence to identify a population of unconventional T cells that exist in the small intestinal epithelium, which appear to depend on commensal microbes, and show that a single commensal microbe (that encodes an antigen capable of weakly stimulating these cells) is sufficient to maintain this T cell population.

  This valuable study employs a diverse array of techniques encompassing cell biological manipulations, biophysical measurements, and mouse models to elucidate the impact of target cell stiffness on CD8+ cytotoxic T cell activation, with a particular focus on the actin nucleator protein WASP. The finding that WASP is essential for the stiffness-dependent phosphorylation of ZAP70 in CD8 T cells is convincing. However, the data regarding the role of WASP in mechanosensing within CD8 T cell-mediated anti-tumor immunity is incomplete and would benefit from a more rigorous study design. This work would be of interest to cell biologists and investigators studying mechanosensing within the immune system.
