Constitutive membrane expression of proteinase 3 (PR3) and neutrophil activation by anti-PR3 antibodies.
Antineutrophil cytoplasm autoantibodies with specificity for proteinase 3 (PR3) are thought to play a major role in the pathogenesis of Wegener's granulomatosis (WG), presumably by their potential to activate neutrophils. In patients with WG, high expression of PR3 on the surface of nonprimed neutrophils is associated with an increased incidence and rate of relapse. In this study, we analyzed t...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Extraction and Purification of Anti-Proteinase 3 (PR3) Antibodies from Egg Yolk
Recently it has been reported, that immunoglobulin Y (IgY) can be used instead of polyclonal antibodies extracted from mammals (IgG) for the purpose of diagnosis and therapy. These antibodies are found to have better properties in terms of specificity and ease of large-scale production. In addition, IgY binds neither to mammalian complement or Fc-receptors nor does it interfere with rheumatoid ...
متن کاملWegener's granulomatosis--autoimmunity to neutrophil proteinase 3.
Wegener's granulomatosis (WG) is a small-vessel vasculitis associated with various clinical manifestations, among which the most common are respiratory tract disease and glomerulonephritis leading to renal failure. The pathogenesis of vascular injury in WG is ascribed to antineutrophil cytoplasmic antibodies (ANCA) directed mainly against proteinase 3 (PR3), an enzyme from neutrophil granules. ...
متن کاملEXPRESSION OF HUMAN PROTEINASE 3 IN CHINESE HAMSTER OVARY CELLS (CHO-CELLS)
Proteinase 3(PR3) is a human polymorphonuclear leukocyte serine proteinase and is the main target antigen for antineutrophil cytoplasmic antibodies (ANCA) found in Wegener's granulomatosis (WG). We developed a stable expression system for conformationally intact recombinant PR3 (rPR3) in Chinese hamster ovary cells (CHO-cells). The part of PR3 cDNA that encoded the active form of PR3 was s...
