Antibodies to proteinase 3 mediate expression of vascular cell adhesion molecule-1 (VCAM-1).

1996

SUMMARY VCAM-1 was first identified as an adhesion molecule induced on human endothelial cells (HEC) by inflammatory cytokines such as IL-1, tumour necrosis factor (TNF), and lipopolysaccharide (LPS). The molecule binds to a variety of leucocytes, including B cells, T cells, basophils, eosinophils and monocytes. Vascular expression of VCAM-1 has been associated with a number of disease states, including rheumatoid arthritis and vasculitis. The detection of antineutrophil cytoplasmic antibodies (ANCA), especially to proteinase 3 (PR3), has become important in the diagnosis of Wegener’s granulomatosis (WG) and related vasculitides. Recently we were able to demonstrate a direct effect of anti-…

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 …

Anti‐laminin auto antibodies in ANCA‐associated vasculitis

2000

Background. Endothelial cell damage occurs during vasculitic processes in vivo. With the alteration of the endothelium, exposure to basement membrane components may occur with induction of humoral immunity. Methods. In the present study, we evaluated the prevalence of antibodies against the basement membrane antigen laminin (LMN) in patients with ANCA-associated systemic vasculitis (AASV), pathologic controls (systemic lupus erythematosus, mixed cryoglobulinaemia, Henoch Schonlein purpura, primary glomerulonephritis) and normal individuals. Results. By ELISA, 21.6% of AASV (16/74) and 10% of pathologic controls (3/30), but only one of the normal controls (2.8%) had these antibodies (P = 0.0…
