Description : Wegener granulomatosis (WG) is a systemic disease with a complex genetic background.
It is characterized by necrotizing granulomatous inflammation of the upper and lower
respiratory tract, glomerulonephritis, vasculitis, and the presence of antineutrophil
cytoplasmatic autoantibodies (ANCAs) in patient sera. These ANCAs are antibodies to
a defined target antigen, proteinase-3 (PR3, PRTN3; 177020), that is present within
primary azurophil granules of neutrophils (PMNs) and lysozymes of monocytes. On cytokine
priming of PMNs, PR3 translocates to the cell surface, where PR3-ANCAs can interact
with their antigens and activate PMNs. PMNs from patients with active WG express PR3
on their surface, produce respiratory burst, and release proteolytic enzymes after
activation with PR3-ANCAs. The consequence is a self-sustaining inflammatory process
