Abstract
T helper cells, especially Th1 and Th17 cells, were reported to play a pivotal role in the pathogenesis of inflammatory bowel disease (IBD). However, the underlying factors regulating T cell functions in IBD progression remain to be fully elucidated. Here, we revealed that IL-17RD/Sef exacerbates DSS-induced colitis by regulating the balance of T cell subsets and their secretion of associated cytokines. We also observed that IL-17RD/Sef promotes colitis-associated tumorigenesis and negatively correlates with survival in both mouse and colorectal cancer patients. Our results suggested that IL-17RD/Sef functions as a regulator of T cell subsets to promote the inflammatory responses in the pathogenesis of IBD and colitis-associated colon cancer.
