Outline of Final Research Achievements

We constructed new in vivo imaging system to observe process of leukocyte migration via adhesion on endothelium. This system did not capture the migration via adhesion, suggesting that increment of residual leukocytes may cause accumulation of leukocytes in intima. Furthermore, these leukocytes were positive for CD11b, CD11c, MHC class2, CCR2, CD40, CD80 and CD86 but not F4/80 and Ly6G, suggesting that residual leukocytes may be new cell type.
