Renal tubule injury: a driving force toward chronic kidney disease
Publication in refereed journal


摘要Renal tubules are the major component of the kidney and are vulnerable to a variety of injuries including hypoxia, proteinuria, toxins, metabolic disorders, and senescence. It has long been believed that tubules are the victim of injury. In this review, we shift this concept to renal tubules as a driving force in the progression of kidney diseases. In response to injury, tubular epithelial cells undergo changes and function as inflammatory and fibrogenic cells, with the consequent production of various bioactive molecules that drive interstitial inflammation and fibrosis. Innate immune-sensing receptors on the tubular epithelium also aggravate immune responses. Necroinflammation, an autoamplification loop between tubular cell death and interstitial inflammation, leads to the exacerbation of renal injury. Furthermore, tubular cells also play an active role in progressive renal injury via emerging mechanisms associated with a partial epithelial-mesenchymal transition, cell-cycle arrest at both G1/S and G2/M check points, and metabolic disorder. Thus, a better understanding the mechanisms by which tubular injury drives inflammation and fibrosis is necessary for the development of therapeutics to halt the progression of chronic kidney disease.
