Among all the methods of microbial perception, T cells enable the widest spectrum of microbial recognition resolution, ranging from the crudest detection of whole groups of microbes to the finest detection of specific antigens. The application of this recognition capability to the crucial task of combatting infections has been the focus of classical immunology. We now appreciate that the coevolution of the immune system and the microbiota has led to development of a lush immunological decision tree downstream of microbial recognition, of which an inflammatory response is but one branch. In this review we discuss known T cell-microbe interactions in the gut and place them in the context of an algorithmic framework of recognition, context-dependent interpretation, and response circuits across multiple levels of microbial recognition resolution. The malleability of T cells in response to the microbiota presents an opportunity to edit immune response cellularity, identity, and functionality by utilizing microbiota-controlled pathways to promote human health.</p>","PeriodicalId":8271,"journal":{"name":"Annual review of immunology","volume":"40 ","pages":"559-587"},"PeriodicalIF":26.9,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9296687/pdf/nihms-1823890.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9354672","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}

Primarily fueled by the purported proinflammatory role of eosinophils in eosinophil-associated diseases, a series of anti-eosinophil therapeutics have emerged as a new class of drugs. These agents, which dramatically deplete eosinophils, provide a valuable opportunity to characterize the consequences of eosinophil knockout humans. Herein, we comparatively describe mouse and human eosinophil knockouts.

ILC2s are associated with the severity of allergic asthma, and experimental models of lung inflammation have shown how they act as playmakers, receiving signals variously from stromal and immune cells as well as the nervous system and then distributing cytokine cues to elicit type 2 immune effector functions and potentiate CD4<sup>+</sup> T helper cell activation, both of which characterize the pathology of allergic asthma.

However, the underlying molecular mechanisms of DNA-triggered immune response have remained elusive until recent years. Cyclic GMP-AMP synthase (cGAS) is a major cytoplasmic DNA senor in various types of cells that detect either invaded foreign DNA or aberrantly located self-DNA. Upon sensing of DNA, cGAS catalyzes the formation of cyclic GMP-AMP (cGAMP), which in turn activates the ER-localized adaptor protein MITA (also named STING) to elicit the innate immune response. The cGAS-MITA axis not only plays a central role in host defense against pathogen-derived DNA but also acts as a cellular stress response pathway by sensing aberrantly located self-DNA, which is linked to the pathogenesis of various human diseases. In this review, we summarize the spatial and temporal mechanisms of host defense to cytoplasmic DNA mediated by the cGAS-MITA axis and discuss the association of malfunctions of this axis with autoimmune and other diseases.

Local and systemic hyporesponsiveness to dietary antigens, classically referred to as oral tolerance, comprises a distinct complement of adaptive cellular and humoral immune responses. It is increasingly evident that a functional epithelial barrier engaged in intimate interplay with innate immune cells and the resident microbiota is critical to establishing and maintaining oral tolerance. Moreover, innate immune cells serve as a bridge between the microbiota, epithelium, and the adaptive immune system, parlaying tonic microbial stimulation into signals critical for mucosal homeostasis.
