Project description:To investigate the effect of cholic acid sulfate to MAIT cells, PBMCs were stimulated with each antigen (5-OP-RU, cholic acid sulfates; CA3S and CA7S) and scRNA sequencing was performed. the homeostatic related genes expressed in cholic acid sulfate stimulation, while the inflammatory related gene expressed in 5-OP-RU stimulation. This analysis showed that cholic acid sulfate contributes to maintenance of MAIT cells.

Project description:To investigate the contribution of novel antigen for MAIT cells; Cholic acid sulfate, we established Sult2a KO mice lacking antigen-producing the enzyme. We performed scRNA sequencing of whole thymocyte and liver cells from these and wild type mice. Sult2a was deficient in hepatocytes, whereas there was no change in other genes or cell proportions, suggesting that deficient of Sult2a did not affect to other genes. The analysis of thymocye implied that cholic acid sulfate may have affected the MAIT subsets.

Project description:Mucosal-Associated Invariant T (MAIT) cells recognize the riboflavin pathway-derived metabolite 5-(2-oxopropylideneamino)-6-d-ribitylaminouracil (5-OP-RU) presented by the MHC-Ib molecule MR1. Both MR1 and the T cell receptor genes used by MAIT cells are under strong evolutionary pressure in mammals, suggesting an important role of 5-OP-RU-specific T cells across species. In humans and mice, MAIT cells acquire distinctive effector functions linked to the expression of the master transcription factor ZBTB16 (PLZF) during thymic development. Conservation of a unique differentiation program in 5-OP-RU-specific T cells from other species is unclear. Here, we used single-cell RNA sequencing to characterize the development of 5-OP-RU-specific T cells in 6 species spanning 110 million years of mammalian evolution. Cross-species comparative analyses revealed a conserved sequence of transcriptional events underlying the maturation of 5-OP-RU-specific thymocytes, marked by the early expression of ZBTB16 in all species. MAIT cells also co-expressed the transcription factors TBX21 (Tbet) and RORC (RORgt) in human, sheep, cattle and opossum. By contrast, Tbet and RORgt were expressed by distinct subsets of MAIT cells in the thymus of rodents, including pet mice and >30 genetically diverse mouse strains, dismissing a laboratory mouse artifact. In mice, RORgt+ MAIT cells further matured in the mesenteric lymph nodes and intestines to acquire a transcriptional program remarkably conserved in MAIT cells from non-rodent species and characterized by co-expression of type 1 and type 17 effector genes, but also genes associated with cytotoxicity and tissue repair. Thus, we define a deeply conserved transcriptional program for 5-OP-RU-specific T cells, which may help understand their functions.
