| Outline of Final Research Achievements |
In cementblast forming hard tissue as osteoblast, F-spondin not only promotes calcification but also inhibits IL-6 expression and PGE2 production stimulated by LPS, and it suppresses osteoclast differentiation. In this study, we examined effects of F-spondin on the anti-inflammatory reaction to osteoblast and the inhibition of alveolar bone resorption. In osteoblasts, F-spondin suppressed IL-6 expression in vitro study. In vivo study, the alveoral bone resorption caused by Inflammation was suppressed in the F-spondin overexpressing transgenic mice, but it was difficult to control the periodontitis by use of F-spondin peptide in vivo study.
