Outline of Final Research Achievements	The role of cellular CLEC-2 in lymphangiogenesis at the site of inflammation was investigated. In this study, 3% Dextran Sulfate Sodium (DSS)-induced enterocolitis mice were used. CLEC-2 expression was completely terminated by injection of anti-CLEC-2 antibody intraperitoneally. There was no significant difference in clinical manifestations, severity of inflammation, gut weight, or density of lymphatic vessels at the site of inflammation in the presence or absence of CLEC-2. Density of blood vessels at the site of inflammation was significantly decreased. Since the density of blood vessels was decreased while that of lymphatic vessels was not in cellular CLEC-2 terminated mice, it it obvious that CLEC-2 plays a role in angiogenesis at the site of inflammation.
