| Outline of Final Research Achievements |
It is known that diabetic patients with periodontitis are more likely to develop nephropathy than patients without periodontitis, but the mechanism is unknown.In this study, we explored the possibility that glomerular blood vessels express the immune molecule TLR in diabetes and overreact to bacterial components in the
blood, making the glomerulosclerosis. All bacteria in the digestive tract are killed in the liver, but bacteria in the oral cavity go directly into the kidneys.
The present study aims to examine the renal SGLT2 induction by the TLR2/4 ligand Porphyromonas gingivalis lipopolysaccharide in mouse diabetic nephropathy.

| Academic Significance and Societal Importance of the Research Achievements |
糖尿病患者は、口腔衛生状態に気をつけ、歯磨きをすること、もし歯周病があれば早期に治療することで腎症に移行することを予防できる可能性が、マウスを用いた動物実験で示すことができた。糖尿病性腎症の起こる仕組みは多様で、一概に言うことは出来ないが、少しでも糖尿病による透析患者人口を減らすことに貢献できるのではないかと考えている。
