Differences in the molecular signatures of mucosal-associated invariant T cells and conventional T cells.

ABSTRACT: Mucosal-associated invariant T (MAIT) cells exhibit different characteristics from those of TCRα7.2^- conventional T cells. They play important roles in various inflammatory diseases, including rheumatoid arthritis and inflammatory bowel disease. MAIT cells express a single T cell receptor alpha chain, TCRα7.2 segment associated with Jα33 and CDR3 with fixed length, which recognizes bacteria-derived vitamin B metabolites. However, the characteristics of MAIT cells and TCRα7.2⁺ CD161^- T cells have never been compared. Here, we performed RNA sequencing to compare the properties of MAIT cells, TCRα7.2^- conventional T cells and TCRα7.2⁺ CD161^- T cells.
