| Outline of Final Research Achievements |
Acute inflammation as a cause of infection occasionally expands to whole body, which gives rise to fatal systemic infection. Apart from previous approaches focusing on identification of critical mediators, our focus is on microenvironments that help a variety of mediators’ action, also degrading process of extracellular matrices. Heparanase is an enzyme involved in basement membrane degradation as well as enhanced release of inflammatory mediators resulting from cleavage of heparan sulfate. Our goal is to elucidate how inflammatory reaction is regulated by cleavage of sulfated carbohydrates, also to suppress inflammation through inhibition of heparanase activity. We examined a novel regulatory mechanism of inflammation of via cleavage of heparin sulfate/heparin, therapeutic effect of a heparanase inhibitor on inflammatory diseases, and a novel proinflammatory cytokine-like action of heparanase.
