Outline of Final Research Achievements

In order to clarify the relationship between diabetes and periodontal disease, this study focused on sphingolipids, which have a significant effect on glucose metabolism. In this experiment, it was revealed that the enzyme that synthesizes sphingomyelin, which is one of the sphingolipids, regulates the differentiation of osteoclasts. It is suggested that sphingolipids may affect the interaction between diabetes and periodontal disease because sphingomyelin is significantly involved in glycolipid metabolism.

Academic Significance and Societal Importance of the Research Achievements

近年の肥満症、メタボリックシンドローム患者の急増によって、インスリンを中心とした内分泌・エネルギー代謝の研究は世界中で盛んに行われており、申請者らは骨から産生するホルモンが糖脂質代謝に重要な役割をすることを明らかにするなど、骨組織を中心とした多臓器間ネットワークによる生理機能調節機構を明らかにしてきた。今回の結果はスフィンゴミエリンをターゲットにした糖尿病患者の歯周病治療応用へと展開する可能性が示唆された。
