Activation of Epithelial STAT1 by Interleukin 28 Controls Mucosal Healing in Mice with Colitis and is Increased in Mucosa of Patients With Inflammatory Bowel Disease

We investigated the roles of interleukin 28A (also called IL28A or interferon lambda 2) in intestinal epithelial cell (IEC) activation, studying its effects in mouse models of inflammatory bowel diseases (IBD) and intestinal mucosal healing.
