Activated MAIT cells exhibit T helper 1 (Th1)/Th17 secretion patterns, such as interferon gamma (IFNγ), tumor necrosis factor alpha (TNF-α), and IL-17, and may be involved in the pathogenesis of various inflammatory diseases [14,15] and metabolic diseases [14,16,17,18,19]. This evidence concerns the gene IFNG and Other metabolic disease.
