Abstract: Inventor's general objective was to investigate the potential role of mucosal thrombin in intestinal inflammation and its mechanisms of action. First, they evaluated whether there is an increased presence of active thrombin in Crohn's Disease (CD): both in patient tissues and in an animal models of IBD. Second, they investigated the effects on mucosal damage and tissue dysfunction resulting from the intracolonic administration of thrombin at a dose comparable to what was detected in the tissue of CD patients. Third, they demonstrated in IBD mouse model that pharmacological inhibition of mucosal thrombin activity is a new therapeutic approach to this debilitating condition, such inhibition, allows to significantly decrease all inflammatory parameters including the fecal bleeding score.

Abstract: The invention is in the field of therapy of gut inflammatory diseases such as Inflammatory Bowel Diseases (IBD) or Irritable Bowel Syndrome (IBS) including Gluten hypersensitivity. The inventors showed that ELA2A secreted by epithelial cells in the extracellular space is over-expressed in IBD conditions degrading tight junction proteins and controlling cytokines expression. Overexpression of ELA2A conferred a pro-inflammatory phenotype both in cell expression systems and in vivo in animal model of IBD. The inventors also showed that ELA2 over-expressing intestinal epithelial cells increase the release of CXCL8 protein compared to control cells. The increased CXCL-8 protein release observed in cells overexpressing ELA2A is inhibited by ELAFIN addition to the culture, in a dose-dependent manner. In particular, the invention relates to inhibitors of Elastase ELA2A, for use in the treatment of Inflammatory Bowel Diseases, such as Crohn's Disease, Ulcerative Colitis, Celiac disease, and Pouchitis.

Abstract: The subject matter of the present invention is a method for differentiating epithelial stem cells, comprising culturing one or more epithelial stem cells in contact with an extracellular matrix in the presence of an expansion medium, a bovine pituitary extract, a receptor tyrosine kinase ligand, a supernatant of primary fibroblasts and optionally, a Rho kinase inhibitor.
