The Mechanistic Role of Different Mediators in the Pathophysiology of Nephropathy: A Review

Curr Drug Targets. 2022 Oct 26. doi: 10.2174/1389450124666221026152647. Online ahead of print.ABSTRACTNephropathy has become the most common reason for end-stage renal disease worldwide. The progression of end-stage renal disease occurs caused by decreased glomerular filtration rate, damage to capillaries in renal glomeruli or a higher risk of cardiovascular morbidity and mortality in diabetic patients. The involvement of mechanism in the development of nephropathy via generation of AGEs, the elevation of growth factors, altered hemodynamic and metabolic factors, inflammatory mediators, oxidative stress and dyslipidaemia. The prevalence of chronic kidney disease in India will rise from 3.7 million in 1990 to 7.63 million in 2020 becoming the main cause of mortality and morbidity. The pathogenesis of nephropathy mediates by various molecules that cause alterations in the structure and function of the kidney like growth factors, endothelins, transforming growth factor (TGF-β), and Angiotensin-converting enzymes (ACE), fibronectin and pro-inflammatory cytokines, mast cells and dyslipidemia. Growth factors like VEGF, IGFs, PDGF, EGFR and TGF-β contribute to excessive extracellular matrix accumulation, together with thickening of the glomerular and tubular basement membranes and an increase in the mesangial matrix, leading to glomerulosclerosis and tubulointerstitial fibrosis. Oxidative stress and inflammation factors like TNF-α, IL-1 and IL-6 are hypothesized to play a role in...
