Research Abstract |
Flagellin, the ligand of Toll like receptor 5, markedly increased the expression of MCP-1 which is one of the CC chemokine, in a dose-dependent manner on osteoblastic MC3T3-E1 cells. In addition, flagellin was significantly suppressed the OPG mRNA expression. Furthermore, anti-MCP-1 antibody was further down-regulated the flagellin-suppressed OPG mRNA expression. These results indicate that osteoblasts are involved in host defense as well as bone metabolism.
