Abstract:
Ulcerative colitis (UC) is one of the main types of inflammatory bowel disease (IBD). It is a chronic, nonspecific, and inflammatory disease of the colon that is prone to repeated attacks and requires long-term maintenance treatment. Its clinical features include: diarrhea, weight loss, abdominal pain, fever, blood in the stool and the risk of cancer. It is currently believed that the pathogenesis of UC is due to environmental factors acting on genetically susceptible individuals, causing abnormal activation of the immune system and destruction of the intestinal mucosal barrier, resulting in inflammatory changes of the colonic mucosa, in which T cells and cytokines secreted by them is the important topics in UC pathogenesis research. Th9 cells are a newly discovered subset of T cells. IL-9 secreted by it has been shown to be involved in a variety of autoimmune disease. Now we will review the differentiation of Th9 cells and the mechanisms involved in the pathogenesis of UC.
