Anti-neutrophil cytoplasmic antibodies (ANCA) against proteinase 3 (PR3) are postulated to injure vascular endothelium by inducing cytokine-primed neutrophils to release proteolytic enzymes and generate reactive oxygen species. Anti-PR3 induce exocytosis, and since priming is associated with upregulation ...
These anti-PR3 antibodies (PR3-ANCA) bind and cross-link membrane PR3 (mPR3) causing neutrophil activation11,12 which then contributes to necrotizing vasculitis. While all neutrophils contain PR3 intracellularly, the mPR3 pattern is remarkable in that two distinct subsets exist, one displaying ...
First- and second-generation ELISA for the detection of antineutrophil cytoplasmic antibodies (ANCA) frequently demonstrate insufficient sensitivity due to inadequate presentation of autoantigenic epitopes. Human PR3 was immobilized on the solid phase of ELISA plates by anchoring technique. Anti-PR3 ...
Proteinase 3 (PR3), which is also called myeloblastin, the target autoantigen for antineutrophil cytoplasmic antibodies (ANCA) in Wegener's granulomatosis, is a serine proteinase stored in azurophil granules of human neutrophils. We have previously shown that, in contrast to elastase or ...
Antineutrophil cytoplasmic antibodies (ANCA) targeting proteinase 3 [PR3; cytoplasmic ANCA (c-ANCA)], a leukocyte serine protease, are highly specific for Wegeners Granulomatosis (WG). A pathogenetic role for c-ANCA has been proposed as a result of their ability of activating neutrophils, whereas...

In a group of autoimmune vasculitides associated with anti-neutrophil cytoplasmic antibodies (AAVs), granulomatosis with polyangiitis (GPA) illustrates the concept that autoimmunity can develop against one specific neutrophil protein, namely, proteinase 3 (PR3), one of the four serine protease homologs ...
