How these cells integrate distinct local cues to adopt the common T<sub>RM</sub> cell fate remains poorly understood. Here, we show that whereas skin T<sub>RM</sub> cells strictly require transforming growth factor β (TGF-β) for tissue residency, those in other locations utilize the metabolite retinoic acid (RA) to drive an alternative differentiation pathway, directing a TGF-β-independent tissue residency program in the liver and synergizing with TGF-β to drive T<sub>RM</sub> cells in the small intestine. We found that RA was required for the long-term maintenance of intestinal T<sub>RM</sub> populations, in part by impeding their retrograde migration. Moreover, enhanced RA signaling modulated T<sub>RM</sub> cell phenotype and function, a phenomenon mirrored in mice with increased microbial diversity. Together, our findings reveal RA as a fundamental component of the host-environment interaction that directs immunosurveillance in tissues.","PeriodicalId":13269,"journal":{"name":"Immunity","volume":null,"pages":null},"PeriodicalIF":32.4,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431863","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, using <em>in vivo</em> CRISPR-Cas9 screens, we uncovered organelle signaling and metabolic processes shaping CD8<sup>+</sup> tissue-resident memory T (T<sub>RM</sub>) cell development. T<sub>RM</sub> cells depended on mitochondrial translation and respiration. Conversely, three nutrient-dependent lysosomal signaling nodes—Flcn, Ragulator, and Rag GTPases—inhibited intestinal T<sub>RM</sub> cell formation. Depleting these molecules or amino acids activated the transcription factor Tfeb, thereby linking nutrient stress to T<sub>RM</sub> programming. Further, Flcn deficiency promoted protective T<sub>RM</sub> cell responses in the small intestine. Mechanistically, the Flcn-Tfeb axis restrained retinoic acid-induced CCR9 expression for migration and transforming growth factor β (TGF-β)-mediated programming for lineage differentiation. Genetic interaction screening revealed that the mitochondrial protein Mrpl52 enabled early T<sub>RM</sub> cell formation, while Acss1 controlled T<sub>RM</sub> cell development under Flcn deficiency-associated lysosomal dysregulation. Thus, the interplay between nutrients, organelle signaling, and metabolic adaptation dictates tissue immunity.","PeriodicalId":13269,"journal":{"name":"Immunity","volume":null,"pages":null},"PeriodicalIF":32.4,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431864","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}

H3.3K27M DMGs, the most aggressive DMG, demonstrated enrichment of DAMs. Genetic ablation of chemokines <em>Ccl8</em> and <em>Ccl12</em> resulted in a reduction of DAMs and an increase in lymphocyte infiltration, leading to increased survival of tumor-bearing mice.

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.
