Patent number: 11692045Abstract: 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.Type: GrantFiled: September 22, 2020Date of Patent: July 4, 2023Assignees: Instutut Nationale de la Santé et de la Recherche Médicale, Université Toulouse III—Paul Sabatier, Centre Nationale de la Recherche Scientifique (CNRS)Inventors: Nathalie Vergnolle, Corinne Rolland, Céline Deraison-Manuel

Hybrid superconductive wires or ribbons comprising a chevrel phase and another superconductive phase
Patent number: 4808488Abstract: A hybrid superconductive fiber or strand comprises at least two layers surrounding a core wherein the fiber or strand comprises two superconductive materials. One of the superconductive materials is a Chevrel phase, optionally doped, which constitutes one of the layers or the core. The other superconductive material, other than the Chevrel phase, constitutes another layer, optionally lacunar, or the core.Type: GrantFiled: May 22, 1987Date of Patent: February 28, 1989Assignee: Centre Nationale de la Recherche Scientifique (CNRS)Inventors: Roger A.
