Outline of Research at the Start

2型糖尿病患者は、歯周炎の発症率や進行度が高く治療に抵抗性である。先行研究では、miR-1260bが小胞体(ER)ストレス応答蛋白であるATF6βの発現制御 を介して歯槽骨吸収抑制効果を示すことを世界に先駆けて発見した。歯周炎モデルマウスではERストレスが誘導されるが、2型糖尿病の原因である肥満もERストレスを誘導し、インスリン抵抗性を惹起する。しかし、ATF6βがインスリン抵抗性を介して歯周炎の病態に影響を及ぼすか否かは不明である。

本研究では、①ATF6βの2型糖尿病患者における歯周炎増悪への関与を検討し、②miR-1260bのERストレス制御による2型糖尿病性歯周炎への治癒効果を検証する。

Outline of Final Research Achievements

Patients with type 2 diabetes exhibit a higher incidence and more aggressive progression of periodontitis, with treatment resistance. Previous studies have revealed that miR-1260b regulates the expression of the endoplasmic reticulum (ER) stress response protein ATF6β, thereby suppressing alveolar bone resorption. Obesity, a major cause of type 2 diabetes, induces ER stress and leads to insulin resistance. However, whether ATF6β is involved in periodontitis pathogenesis through insulin resistance remains unclear. In this study, we demonstrate that under hyperglycemic conditions, the induction of ATF6β expression in response to ER stress is suppressed. On the other hand, we confirmed the expression of NFAT5 in periodontal tissues affected by periodontitis. NFAT5 is known to be induced under conditions of hyperglycemia and ER stress, suggesting that NFAT5 may be a potential therapeutic target for periodontitis in type 2 diabetes.

Academic Significance and Societal Importance of the Research Achievements

高血糖条件下では、マクロファージにおける小胞体ストレス関連遺伝子の発現が正常血糖条件とは異なることが明らかとなった。また、高血糖およびERストレスにより誘導されるNFAT5について、マウス歯周炎歯肉組織でその発現が増強されていることを確認した。この結果は、2型糖尿病性歯周炎においてNFAT5が治療のターゲットとなる可能性を示唆している。NFAT5は高血糖やERストレスによって誘導されることが知られており、その発現増強が歯周炎の病態形成に関連することが示唆された。今後、ERストレスとNFAT5の関連をさらに解明することが、2型糖尿病性歯周炎の新たな治療法の開発に貢献する可能性がある。
