CD8A and endometriosis: did not identify differences in the overall CD8+ MAIT population between endometriosis patients and controls (the majority of MAIT cells are CD8+), they found an increased frequency of CD8+ cells among MAIT subtypes in the peripheral blood of patients as well as controls when compared to global CD8 T cells (p = 0.003 and p = 0.0002, respectively) (41).
