  • COMPOSITION COMPRISING EXPRESSION OR ACTIVITY INHIBITORS OF NINJURIN 1 FOR THE PREVENTION AND TREATMENT OF INFLAMMATORY DISEASE
    Publication number: 20110123538
    Abstract: The present invention relates to a composition comprising a Ninjurin 1 expression or activity inhibitor for the prevention and treatment of inflammatory disease. Ninjurin 1 protein is specifically expressed in macrophages around blood vessels, increases cell-cell adhesion and cell-matrix adhesion, increases expressions of Wnt7b (Wingless-type MMTV integration site family, member 7B) and Ang2 (angiopoietin-2), but reduces expression of Ang1 to induce apoptosis of vascular endothelial cells. In addition, Ninjurin 1 protein is up-regulated when inflammation is induced and induces iNOS expression as well as increased NO generation. Therefore, the Ninjurin 1 protein expression or activation inhibitor can be effectively used as an active ingredient of a composition for the prevention and treatment of inflammatory disease.
