)
• microcysts
|
• focal injury to the parietal epithelium lining Bowman's capsule
|
• focal loss of primary processes of podocytes, and hyperplastic and hypertrophic podocytes
• diseased podocytes contain abnormal mitochondria
|
• extensive foot process effacement with marked condensation of the actin cytoskeleton
|
• folding and wrinkling of the glomerular basement membrane
|
• variable, age-dependent penetrance of collapsing glomerulopathy; segmental and global collapse of capillary loops with folding and wrinkling of the glomerular basement membrane
|
• diseased glomeruli show segmental and global sclerosis
|
• tubular atrophy
|
cellular
• impaired mitochondrial respiration
|
• significant decrease in complex I and complex II-dependent respiratory chain capacity in liver
