| Research Abstract |
Th17 cells, one of T helper subsets, secrete interleukin-17 (IL-17), IL-17F, and IL-22 and have significant roles in protecting the host from bacterial and fungal infections, as well as autoimmune diseases. I have demonstrated that Th17 cells are abundant in intestinal mucosa and Th17 cell accumulation in gut is induced by segmented filamentous bacteria (SFB). At the same time, the accumulation of regulatory T cells (Tregs) in gut is mediated by Clostridium species.
