How does proteinase 3 interact with lipid bilayers?

Proteinase 3 (PR3) is a serine protease of the neutrophils whose membrane expression is relevant in a number of inflammatory pathologies. It has been shown to strongly interact with reconstituted bilayers containing dimyristoylphosphatidylcholine (DMPC), dimyristoylphosphatidylglycerol (DMPG) or mixtures of both phospholipids. Here we present the results of molecular dynamics simulations of PR3...

Highly selective water channel activity measured by voltage clamp: analysis of planar lipid bilayers reconstituted with purified AqpZ.

Aquaporins are membrane channels selectively permeated by water or water plus glycerol. Conflicting reports have described ion conductance associated with some water channels, raising the question of whether ion conductance is a general property of the aquaporin family. To clarify this question, a defined system was developed to simultaneously measure water permeability and ion conductance. The...

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 ...

Acetylcholine receptor in planar lipid bilayers. Characterization of the channel properties of the purified nicotinic acetylcholine receptor from Torpedo californica reconstituted in planar lipid bilayers

The properties of the channel of the purified acetylcholine receptor (AChR) were investigated after reconstitution in planar lipid bilayers. The time course of the agonist-induced conductance exhibits a transient peak that relaxes to a steady state value. The macroscopic steady state membrane conductance increases with agonist concentration, reaching saturation at 10(-5) M for carbamylcholine (...

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...
