There is no single necrotic pathway either, as compelling evidence exists for distinct necrotic modalities such as pyroptosis, necroptosis and ferroptosis. The recent momentum of molecular, structural and disease-relevant findings has opened the door to targeting necrotic machinery to prevent collateral tissue damage and inflammatory diseases. In this Review, we evaluate the case for targeting the necrotic cell death pathway called necroptosis. We examine the organs and cell types where the human necroptotic machinery is expressed, identifying a lymphocytic ZBP1, RIPK1, RIPK3 and MLKL signature, review knowledge into the immunogenic consequences of necroptotic signaling and highlight building evidence that necroptosis is engaged in humans and can be triggered by ischemic injuries. Finally, we note several limitations of mouse studies due to fundamental differences with the human necroptotic apparatus and critically appraise the evidence for necroptosis being a disease-driving factor that, if successfully targeted, could be of clinical benefit.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"11 1","pages":""},"PeriodicalIF":30.5,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145296313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In viral infections, TIGIT alone does not affect viral control but has been shown to limit tissue pathology. However, the underlying mechanisms are incompletely understood. Here we found TIGIT+ T cells to express not only an immunoregulatory gene signature but also a tissue repair gene signature. Specifically, after viral infection, TIGIT directly drives expression of the tissue growth factor amphiregulin (Areg), which is strongly reduced in the absence of TIGIT. We identified regulatory T (Treg) cells, but not CD8+ T cells, as the critical T cell subset mediating these tissue-protective effects. In Treg cells, TIGIT engagement after T cell antigen receptor stimulation induces the transcription factor Blimp-1, which then promotes Areg production and tissue repair. Thus, we uncovered a nonclassical function of the co-inhibitory receptor TIGIT, wherein it not only limits immune pathology by suppressing the immune response but also actively fosters tissue regeneration by inducing the tissue growth factor Areg in T cells.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"1 1","pages":""},"PeriodicalIF":30.5,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145296136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we investigated the durability of humoral immunity induced by an influenza vaccine based on AS03-adjuvanted chimeric hemagglutinin (cHA) in nonhuman primates (NHPs). Two groups of NHPs received two doses of a seasonal quadrivalent influenza vaccine, followed by sequential immunization with split virus cHA vaccines cH8/1N1, and cH5/1N1. One group received cHA immunizations with AS03 adjuvant. We monitored serum antibodies and long-lived plasma cells in bone marrow for nearly 2 years after the final vaccination. cHA vaccines induced stalk-specific antibody responses. The addition of AS03 enhanced both the magnitude and durability of humoral immunity by establishing long-lived plasma cells in the bone marrow and lymph nodes for nearly 2 years. Passive transfer of NHP serum provided protection against challenge with heterologous influenza A virus strains in mice.

Here we report that peripheral pDCs in naive mice comprise three subsets (termed A, B and C) that represent progressive differentiation stages. This heterogeneity was generated by tonic IFN-I signaling elicited in part by the cGAS/STING and TLR9 DNA-sensing pathways. A small 'IFN-I-naive' subset (pDC-A) could give rise to other subsets; it was expanded in STING deficiency or after the IFN-I receptor blockade, but was abolished by exogenous IFN-I. In response to RNA viruses, pDC-A showed increased Bcl2-dependent survival and superior IFN-I responses, but was susceptible to virus infection. Conversely, the majority of pDCs comprised the 'IFN-I-primed' subsets (pDC-B/C) that showed lower IFN-I responses and poor survival, but did not support virus replication. Thus, tonic IFN-I signaling decreases the cytokine-producing capacity and survival of pDCs but increases their virus resistance, facilitating optimal antiviral responses.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"1 1","pages":""},"PeriodicalIF":30.5,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145288402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we used an integrated approach of dynamic human, humanized mouse and non-human primate models and sampling of efferent lymph fluid to determine recirculation and TR patterns of human NK cells. By intravascular labeling, we showed that CD56bright NK cells access tissue niches at steady state. Furthermore, in human liver transplantation, donor-derived CD56bright NK cells represent the dominant TR NK cell population early after transplantation, but are replaced over time by infiltrating recipient NK cells that establish TR traits, a process partly regulated by Runx3. Transient TR CD56bright NK cells recirculated via lymphatics, displaying a consistent phenotype detectable in draining lymph nodes and efferent lymph fluid, and waned from peripheral blood on lymph node egress blockade. Finally, CD56dim NK cells, constrained to vasculature at steady state, entered lymph nodes upon inflammation.

Here, we show that neonatal double-positive mouse thymocytes, unlike their adult counterparts, fail to upregulate Zap70 during thymic selection, creating a calcium signaling bottleneck. This attenuated Zap70-dependent signaling limits negative selection, allowing highly self-reactive clones to evade deletion. Modulating Zap70 expression alters this balance; reducing Zap70 in adults rescues development of these clones, whereas increasing Zap70 in neonates enforces their deletion. Similarly, enhancing neonatal calcium signaling via increased LAT Y136-mediated PLCγ1 activation promotes clonal deletion. Analysis of pediatric human thymi reveals that ZAP70 expression remains low during the first year of life, aligning with the peak window for thymic Treg cell development.
