Th 17 Cells: Role in Inflammation and Autoimmune Disease

The IL-17 cytokines represent a novel family of cytokines, which defines a new effector T cell, the Th17 cell, and extend the Th1-Th2 paradigm. Th17 cells in part co-express at least IL-17A and IL-17F, IL-21 and IL-22. IL-17 A/F are produced by T cells ( and ), iNKT cells, and possibly neutrophils, dendritic cells and Paneth cells. The regulation of IL-17 family member’s expression, and the identification of effector mechanisms are an area of intense current research. Recognized regulators of IL
