| Outline of Final Research Achievements |
11β-HSD1, which converts inactive cortisone to active cortisol intracellularly, has been reported to play a pivotal role in metabolic diseases as well as chronic inflammatory diseases. However, the involvement of 11β-HSD1 in chronic periodontitis has not been investigated. In this study the relationship between chronic periodontitis, the levels of 11β-HSD1 mRNA, and obesity was examined. The expression of 11β-HSD1 mRNA was significantly higher in the chronic periodontitis group than in the controls. Since the expression of 11β-HSD2 mRNA, which inactivates cortisol, was slightly lower in the periodontitis group than in the controls, the ratio of 11β-HSD1 versus 11β-HSD2 mRNA was still higher in the former than in the latter. However, a correlation was not observed between the levels of 11β-HSD1 mRNA and body mass index, an index of obesity. These results suggest that the increased 11β-HSD1 may play a role in the pathology of chronic periodontitis irrespective of obesity.
