Dan Littman: T Helper Cells in Barrier Defense and Inflammatory Disease

In a two-part seminar, Dan Littman discusses the opposing roles of Th17 cells. They protect mucosal surfaces from infection with bacteria and fungi, but they can also cause autoimmune inflammation. Littman also explains that different commensal microbes in our gut elicit different T cell responses, either pathogenic or non-pathogenic.
