Abstract:

Proteinuria of different degrees is the most common clinical manifestation in the progression of chronic kidney disease (CKD). More and more studies showed that persistent proteinuria is closely related to renal tubular injury, as urine protein components can play an important pathophysiological role in the activation of renal tubular structural damage and dysfunction, the mechanism of which includes activation of receptor endocytosis pathway, complement activation, activation of the renin-angiotensin system(RAS), up-regulation of chemokines, and induction of apoptosis, etc. This paper has elaborated on the mechanism of renal tubular injury accelerated by proteinuria, providing important ideas and key targets for prevention and treatment of clinical proteinuria-associated renal injuries.

Key words: Proteinuria, Renal tubule, Activation, Injury
