| Research Abstract |
A role for mucosal associated invariant T (MAIT) cells has recently been reported in several autoimmune diseases, but contribution to inflammatory bowel disease (IBD) has yet to be described. Here, we analyzed the MAIT cells in the peripheral blood of 88 ulcerative colitis patients and 68 Crohn's disease patients, and intestinal mucosae of 5 ulcerative colitis disease patients and 10 Crohn's disease patients. MAIT cells are significantly reduced both in the peripheral blood and the intestinal mucosa of IBD patients. Furthermore, the proportion of MAIT cells producing IL-17 was higher in Crohn's disease patients compared to controls. These results suggest the association of MAIT cells with pathophysiology of IBD.
