| Outline of Final Research Achievements |
We found that renal glomeruli in diabetic environment express toll-like receptors (TLR), and that diabetic mice administering periodontal pathogenic substances become nephropathy but healthy mice do not become nephropathy. TLR is an immune molecule that is primarily expressed on leukocyte, which recognizes bacteria and causes inflammation. Healthy blood vessels do not normally express. In heavy periodontitis, bacteria enter easily into the blood with brushing teeth, so it is thought that in human with both diabetes and periodontitis bacteria enter into the blood and arrive at the kidney, and nephropathy occurs by combining bacteria with TLR which is expressed in diabetic glomeruli. Therefore, it was concluded that treatment and prevention of periodontal disease in human with diabetes is very important for prevention of nephropathy.
