Mucosal-associated invariant T (MAIT) cells are innate-like T cells that are involved in anti-bacterial immunity. MAIT cells are found in the intestine, but their role and distribution within the large intestine have not been fully elucidated. Therefore, we investigated the distribution of MAIT cells within the cecum and colon. Surgically resected tissues of the cecum and colon were obtained from 4 patients with cecal appendix cancer and 8 patients with colorectal cancer, respectively. Lymphocytes were isolated from the intestinal epithelium (intraepithelial lymphocytes, IELs) and the underlying lamina propria (lamina propria lymphocytes, LPLs), and then, MAIT cells were analyzed by flow cytometry. Compared with the colon, the cecum showed a significantly increased frequency of MAIT cells among IELs (P
