| Outline of Final Research Achievements |
We showed that the glomerulus blood endothelial cells with Diabetes mellitus expressed toll-like receptors (TLRs), and that all of the diabetic mice injected with Porphyromonas gingivalis LPS, which is the ligand of TLRs and the causative agent of periodontitis, died for diabetic nephropathy within all survival periods of non-diabetic mice with the LPS likewise. Diabetic nephropathy might be a cause in oral bacteria entering in the circulation because bacteria easily enter into the blood vessels of the patients with severe periodontitis by toothbrushing. The bacteria entering into the circulation at the intestine go to the liver but at the oral and maxillofacial circulation bacteria anatomically reach to kidney. Now, we began the study to prophylactically inhibit diabetic nephropathy by using the TLR antagonists.
