Progress in the study of the role of C5a-induced tubular cell senescence in the progression of diabetic kidney disease

Background Chronic kidney disease (CKD) is the end stage of progressive renal disorders, and effective disease modifying treatments remain elusive. Diabetic kidney disease (DKD) is its leading cause, yet mechanisms and therapies still hold large knowledge gaps. Studies have demonstrated that tubules and interstitium constitute 90 % of renal parenchyma and drive DKD progression; high-glucose milieu induces renal tubular epithelial cell (RTEC) senescence, a process central to DKD onset and worsening.
