The IL23 axis plays a key role in the pathogenesis of IBD

Exciting new results from a genetic study in humans and functional studies in mice have pinpointed interleukin 23 (IL23) and its receptor as a key pathway in the pathogenesis of inflammatory bowel disease (IBD). These findings reveal a hitherto unappreciated role for the IL23 axis in intestinal inflammation and may open new avenues for development of therapeutic strategies in IBD.
