Introduction Glomerular filtration depends on the coordinated function of endothelial cells, the glomerular basement membrane, and podocytes whose interdigitating foot processes form slit diaphragms. Disruption of podocyte architecture—particularly alterations in...

Introduction Reactive oxygen and nitrogen species are continuously generated as by-products of metabolism and environmental stressors, imposing a persistent oxidative load on cellular macromolecules. If left unmanaged, these oxidants disrupt protein structure, damage...
