The role of cationic channels of the potential TRPC receptor in the pathogenesis of idiopathic nephrotic syndrome in children

Abstract

Idiopathic nephrotic syndrome is the most common glomerulopathy in children, with a prevalence of approximately 16 per 100,000 of child population worldwide. Any chronic glomerular disease has the same type of development mechanism. Regardless of the damaging factor, after the death of a significant part of the nephrons, there occurs a steady decrease in the glomerular filtration rate, while morphologically we most often determine focal segmental glomerulosclerosis. Studying the causes of focal segmental glomerulosclerosis is an urgent problem in pediatric nephrology. Recently, there has been discussed the role of the cation channels of the potential receptor TRPC of podocytes in the development of proteinuria and focal segmental glomerulosclerosis. The article provides data on the role of TRPC receptors in the pathogenesis of focal segmental glomerulosclerosis. The authors present their our own data demonstrating gene expression of the cationic channels family of the potential receptor TRPC1, TRPC3, TRPC4, TRPC5 and TRPC6 in children with idiopathic nephrotic syndrome, depending on the morphological picture of the disease and sensitivity to steroid therapy.
