  • Method of treating inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) or gluten hypersensitivity by administering an elastase 2A (ELA2A) inhibitor
    Patent number: 11692045
    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.
