Outline of Final Research Achievements

In this study, I examined to reveal the role of polymerized osteopontin (catalyzed by protein-crosslink enzyme, transglutaminase 2) on inflammation. As a result, it was cleared that osteopontin and transglutaminase 2 were up-regulated by pro-inflammatry cytokine, TGF-β1 and the former was polymerized on cell membrane fraction by the latter. I was also successful in the generation on transgenic mice expressed polymerization-incompetent mutant osteopontin specific in lung.
