Pathogenesis of minimal change disease: hypotheses. Pathogenesis of minimal change disease: hypotheses. In the presence of a normal glomerular basement membrane (shown at the center), with healthy podocyte foot processes (light blue), serum proteins, mainly albumin, remain within the glomerular capillary lumen. Mechanisms, that are as yet not fully elucidated but are partly intrinsic to the podocyte and partly due to the presence of soluble mediators released by a disregulated immune system (see top of the figure and text), modify this integrity. Therefore (red arrow), the actin cytoskeleton of the podocyte and the glomerular basement membrane are disrupted, and albumin and other serum proteins filter out of the bloodstream and into the urinary space. This leads to the intense proteinuria seen in nephrotic syndrome. Marina Vivarelli et al. CJASN 2017;12:332-345 ©2017 by American Society of Nephrology
