  • Patent number: 9580495
    Abstract: Severe glomerulonephritis involves cell necrosis as well as NETosis, programmed neutrophil death leading to expulsion of nuclear chromatin and neutrophil extracellular traps (NETs). Histones released by neutrophils undergoing NETosis killed glomerular endothelial cells, podocytes, and parietal epithelial cells. This was prevented by histone-neutralizing agents anti-histone IgG, activated protein C and heparin. Histone toxicity on glomeruli was TLR2/4-dependent. Anti-GBM glomerulonephritis involved NET formation and vascular necrosis. Pre-emptive anti-histone IgG administration significantly reduced all aspects of glomerulonephritis, including vascular necrosis, podocyte loss, albuminuria, cytokine induction, recruitment and activation of glomerular leukocytes and glomerular crescent formation.
