| Outline of Final Research Achievements |
Elevated blood levels of C-reactive protein (CRP) have been reported in patients with severe periodontitis. Epidemiological studies have indicated the association between periodontitis and metabolic syndrome, which arises from visceral fat-type obesity. In this study, we focused on turnover of extracellular matrix (ECM) protein in adipose tissue and examined the effects of CRP on the expression of matrix metalloproteinases (MMPs) and its inhibitors (TIMPs). CRP increased the expression of MMP-1，-2，-3，-9，-11，-13，-14 and TIMP-1, but not TIMP-2. These results suggest that CRP inclines ECM turnover to the resolution, which may be involved in spread of adipose tissue area, via upregulation of multiple MMPs in adipocyte.
