Abstract
Ulcerative colitis is an idiopathic, chronic inflammatory disease that manifests as diffuse mucosal inflammation of the colon and rectum, and interferes with intestinal motility; however, the exact pathogenesis of UC remains poorly understood. In recent years, the numbers of individuals suffering from UC has been continuously increasing in several countries. The pathogenesis of UC is multifactorial, including immune responses disorders, genetic susceptibility, epithelial barrier defects and environmental factors.
