Glomerular Capillary and Endothelial Cell Injury is Associated with the Formation of Necrotizing and Crescentic Lesions in Crescentic Glomerulonephritis

Abstract

The loss of glomerular capillaries with endothelial cell injury is commonly associated with the formation of necrotizing and cellular crescentic lesions, regardless of the pathogeneses associated with different types of crescentic GN, such as pauci-immune type ANCA-associated GN, anti-GBM GN, and immune-complex type GN. In addition, impaired capillary regeneration and a loss of endothelial cells contribute to the development of glomerular sclerosis with fibrous crescents and glomerular collapse.
