Distribution of human and murine MAIT cells in tissues. The frequency of MAIT cells (defined either by MR1 tetramers or as CD161++Vα7.2+ T cells) within T cells, as has been described in the indicated tissues of mice and humans. MAIT cells are enriched within peripheral organs including the liver and gut, whereas they are less enriched within lymphoid organs. However, MAIT cells are much more abundant in humans compared with common laboratory strains of mice.
