Evidence exists that one regulatory mechanism is a fate-switching process from an IFN-I-secreting pDC to a professional antigen-presenting conventional dendritic cell (cDC) that lacks IFN-I-secreting capacity. However, this differentiation process is controversial owing to limitations in tracking the fate of individual cells over time. Here we use single-cell omics and functional experiments to show that activated human pDCs can lose their identity as IFN-I-secreting cells and acquire the transcriptional, epigenetic and functional features of cDCs. This pDC fate-switching process is promoted by tumor necrosis factor but blocked by IFN-I. Importantly, it occurs in vivo during human skin inflammatory diseases and injury, and physiologically in elderly people. This work identifies the pDC-to-cDC reprogramming trajectory and unveils a mechanistic framework for harnessing it therapeutically. Plasmacytoid dendritic cells are type 1 interferon (IFN-I)-producing antiviral specialists that have been shown to be able to differentiate into conventional dendritic cells. Here the authors show how this differentiation is controlled by tumor necrosis factor driving type 2 conventional dendritic cell-like reprogramming and IFN-I blocking it, a process that occurs during inflammation, injury and aging.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"26 9","pages":"1540-1552"},"PeriodicalIF":27.6,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41590-025-02234-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144819145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we assessed 899 genes in CD8+ T cells responding to murine melanoma and identified the E3 ubiquitin ligase STUB1 as a new negative regulator of anti-tumor CD8+ T cell function. We demonstrated that Stub1 knockout CD8+ T cells effectively control tumor growth across multiple murine models. Mechanistically, STUB1 interacts with the adapter protein CHIC2 to regulate cytokine receptor expression in mouse and human CD8+ T cells. Among the regulated cytokine receptors, interleukin-27 receptor α is essential for tumor growth control mediated by Stub1/Chic2 knockout CD8+ T cells. Together, these findings establish the STUB1–CHIC2 complex as a regulator of cytokine receptor expression in CD8+ T cells and provide rationale for inhibiting this pathway to enhance CD8+ T cell-mediated anti-tumor immunity. LaFleur, Milling et al. perform an in vivo CRISPR screen of CD8+ T cells responding to tumors.

In addition to rapid effector cytokine production and direct cytotoxicity, NK cells exhibit features of adaptive immunity, including the capacity to undergo robust antigen-specific clonal proliferation and to generate immunological memory1–3. However, the transcriptional programs and regulators governing dynamic NK cell responses to viral infection have not been fully uncovered. In this study, we identified transcription factor 19 (TCF19) as a key driver of NK cell proliferation and calcium signaling in the context of mouse cytomegalovirus infection. Ablation of TCF19 was detrimental to NK cell clonal expansion and host protection against viral infection. Tcf19−/− NK cells were also unable to properly mobilize calcium downstream of antigen signaling to mediate cytotoxicity. Altogether, we find that TCF19 drives a transcriptional program that coordinates the innate and adaptive NK cell responses against viral infection. Sun and colleagues report that the transcription factor TCF19 regulates calcium signaling and cell cycling progression in NK cells and is required for innate and adaptive NK cell responses to viral infection.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"26 9","pages":"1467-1475"},"PeriodicalIF":27.6,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144796952","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}

We comprehensively analyzed mammary T cells, revealing a marked increase in CD4+ and CD8+ T effector cells, including an expansion of T cell receptor (TCR)αβ+CD8αα+ cells, in pregnancy and lactation. T cells were localized in the mammary epithelium, resembling intraepithelial lymphocytes (IELs) typically found in mucosal tissues. Similarity to mucosal tissues was substantiated by demonstrating partial dependence on microbial cues, T cell migration from the intestine to the mammary gland in late pregnancy and shared TCR clonotypes between intestinal and mammary tissues, including intriguing public TCR families. Putative counterparts of mammary IELs were found in human breast and milk. Mammary IELs are thus poised to manage the transition from a nonmucosal tissue to a mucosal barrier during lactogenesis. Here Ramanan and colleagues provide an analysis of mammary T cells during late pregnancy and lactation.
