| Outline of Final Research Achievements |
Interleukin (IL)-11 is a member of IL-6 family of cytokines that activates signal transducer and activator of transcription 3. Accumulating studies have shown that IL-11 is highly expressed in inflammatory bowl diseases and colorectal cancers in human and mice. However, it remains unclear whether IL-11 plays a crucial role in maintaining tissue homeostasis of the intestine. In this study, using dextran sodium sulfate (DSS)-induced colitis in mice as a model, we found that IL-11 was produced by non-bone marrow-derived cells that were localized in injured intestinal tissues. Moreover, IL-11 primarily acted on intestinal epithelial cells and protected injury of intestinal epithelial cells, thereby attenuating DSS-induced colitis. These findings indicate that IL-11 plays a crucial for maintaining intestinal homeostasis.
