Pathomorphological sequence of nephron loss in diabetic nephropathy

Based on analysis of 819 human biopsies, essential derangement in diabetic nephropathy consists of accumulation of worn-out glomerular basement membrane in the mesangium that may advance to global sclerosis. The most frequent pathway to nephron dropout starts with the penetration of glomerular capillaries into Bowman’s capsule (BC), delivering an exudate into BC that spreads around the entire glomerular circumference and via the glomerulotubular...
