The role of advanced glycation end products in patogenesis of diabetic nephropathy

Abstract

Diabetes mellitus (DM) and chronic kidney disease are the diseases that have exceeded epidemic thresholds in terms of prevalence all over the world. That made it possible to classify them as non-communicable epidemics of the XXI century. Diabetic nephropathy (DN) is implicated with high levels of disablement and mortality. Advanced glycation end products (AGE) play a key role in the progression of DN. Increased formation of AGE occurs due to hyperglycemia under the conditions of diabetes. Moreover, there are additional factors in DN that increase the elaboration of AGE, such as high levels of oxidative stress and decreased renal clearance which slows down the AGE excretion. Both immediate effects of AGE and interaction of AGE with its cell-bound receptor (RAGE) result in a сascade of events that lead to further progression of DN. Thus, the research of the new therapeutic approaches targeted on the AGE-RAGE system is of great interest to slow progression of DN and improve the prognosis.
