title: Mechanisms of tissue remodeling in inflammatory bowel disease.
abstract: The clinical course of inflammatory bowel disease (IBD) is highly heterogeneous and often unpredictable, with multiple and serious complications that range from stricture formation to bowel obstruction or perforation, fistula formation and the need for surgery. All these problems are manifestations of tissue remodeling, a secondary but universal response to the insults of chronic inflammation. The factors involved in tissue remodeling are several, including the site and duration of inflammation, soluble molecules, the gut microbiota, and the type of mesenchymal cell response. The prototypical and most common type of tissue remodeling in IBD, and Crohn's disease (CD) in particular, is a fibrotic response, and this review will focus on the factors and mechanisms involved in fibrogenesis, and speculate on what is needed for the development of a rational treatment of intestinal fibrosis.
