The Aspect of Anti-Proteinase 3 Antibodies as AECA

2001

Publisher Summary The discovery of anti-neutrophil cytoplasmic antibodies (ANCA) has caused a great impact on the diagnostic procedure and clinical observation of systemic necrotizing vasculitides like Wegener's granulomatosis (WG), microscopic polyangiitis, Churg- Strauss syndrome and necrotizing glomerulonephritis. There is persuasive circumstantial evidence for a pathogenic role of ANCA in ANCA-related vasculitides involving both neutrophils and vascular endothelial cells. The major stepthrough in the pathogenesis of ANCA related diseases was the identification of proteinase-3 (PR-3) as the main target antigen of ANCA in Wegener's Granulomatosis. PR-3 has been described as a constituent …
