This process requires antigen-presenting cells (APCs) that induce T cells with either regulatory or effector functions. Compromised APC function disrupts the T cell balance, leading to inflammation and dysbiosis. Although their precise identities continue to be debated, it has become clear that multiple APC lineages direct the differentiation of distinct microbiota-specific CD4<sup>+</sup> T cell programs. Here, we review how unique APC subsets instruct T cell differentiation and function in response to microbiota and dietary antigens. These discoveries provide new opportunities to investigate T cell-APC regulatory networks controlling immune homeostasis and perturbations associated with inflammatory and allergic diseases.","PeriodicalId":13269,"journal":{"name":"Immunity","volume":"53 1","pages":""},"PeriodicalIF":32.4,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142385778","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}

IFN expression depended on cyclic GMP-AMP synthase (cGAS) and RIG-I-like receptors’ (RLRs) sensing of Mito<sup>+</sup> RBC-derived mitochondrial DNA (mtDNA) and mtRNA, respectively.

Other vascular structures were excluded as alternative T cell routes to intracranial melanomas. Anti-PD-1/CTLA-4 immune checkpoint inhibitors increased intracranial T cell motility, facilitating migration from PVVs to the tumor and subsequently inhibiting intracranial tumor growth. The endothelial adhesion molecule ICAM-1 was particularly expressed on PVVs, and, in samples of human brain metastases, ICAM-1 positivity of PVV-like vessels correlated with intratumoral T cell infiltration.
