Inflammation, oxidative stress, apoptosis, and autophagy in diabetes mellitus and diabetic kidney disease: the Four Horsemen of the Apocalypse

Abstract

Diabetic kidney disease (DKD) can occur in approximately 30-40% of both type 1 and type 2 diabetic patients. The well-established features of DKD include increased serum glucose levels along with chronic low-grade inflammation, OxS, increased advanced glycation end products, sorbitol accumulation, increased hexosamine, and protein kinase C pathway activation. On the other hand, accumulating evidence suggests that novel pathways including apoptosis and autophagy might also play important roles in the pathogenesis and progression of DKD. In this review, the integrated mechanisms of inflammation, oxidative stress, apoptosis, and autophagy are discussed in the pathogenesis as well as progression of DM and DKD.
