| Outline of Final Research Achievements |
We have demonstrated the validity of our hypothesis regarding the development of diabetic nephropathy, which was as follows: AGE-cholesterol-aggregated albumin (ACAA) is formed in the blood flow of diabetic patients, and taken up in glomerular mesangial cells to achieve the breakdown of ACAA in lysosome. Simultaneously, mitochondria of mesangial cells are activated, and mesangial cells are acidified followed by an increase in pro-inflammatory cytokine expression. The cytokines induce inflammation in the glomeruli repeatedly, resulting in diabetic nephropathy. We also clarified the mechanisms for protecting mesangial cells from acidification due to ACAA or an acidic environment. Additionally, our results suggested that ACAA causes damage in mesangial mitochondria followed by apoptosis.
