Abstract

Mucosal-associated Invariant T (MAIT) cells represent a large proportion of T cells in human blood, and are also present throughout the body, being concentrated at mucosal sites. Their high level of conservation throughout mammalian evolution and recognition of conserved microbial antigens, derived from precursors of riboflavin (vitamin B2) biosynthesis, suggest an important role in protective immunity to pathogens. However, the picture that is emerging of MAIT cell immune function is increasingly complex, with numerous correlations of MAIT cell numbers with human diseases, and with recent studies demonstrating their pathogenic potential. The conditions that drive MAIT cell responses towards..
