Abstract:
Diabetic kidney disease (DKD) is one of the serious complications of diabetes mellitus, and it has become the leading cause of chronic renal failure in China. Podocytes are highly differentiated epithelial cells and are the important part of the glomerular filtration barrier. Apoptosis and shedding of podocytes, foot process fusion and decreased expression of slit membrane proteins can lead to proteinuria, which in turn affects the progression of DKD. Autophagy is an important process for eukaryotic cells to degrade cytoplasmic proteins and organelles,the increase of autophagy level helps to reduce podocytes damage. Endoplasmic reticulum stress (ERS) is the accumulation of misfolded proteins in cells. It allows the cells into stress state, and may be able to regulate cell damage in both directions. Autophagy and ERS are regulated by multiple signaling pathways and are considered to be closely related to the occurrence and development of DKD. This article explained some pathways and the role of podocyte autophagy and ERS in DKD, and the interaction between podocyte autophagy and ERS, which providing some potential targets for the treatment of DKD by interfering with podocyte autophagy and ERS.
