WebGlomerular epithelial cells (podocytes) play an important role in the pathogenesis of proteinuria. Podocyte foot process effacement is characteristic for proteinuric kidneys, and genetic defects in podocyte slit diaphragm proteins may cause nephrotic syndrome. A loss of the foot processes of the podocytes (i.e., podocyte effacement) is a hallmark of minimal change disease, which has therefore sometimes been called foot process disease. Disruption of the filtration slits or destruction of the podocytes can lead to massive proteinuria, where large amounts of protein are … See more Podocytes are cells in Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus.
