Inhibition of phospholipase A2.
Phospholipases A2 are involved in inflammatory processes such as the liberation of free arachidonic acid from the membrane pool for the biosynthesis of eicosanoids. Inhibitors of these enzymes are proving useful in determining the biological roles of phospholipases A2 in complex cellular processes and may also have therapeutic potential. Inhibition of these lipolytic enzymes is more difficult t...
متن کاملPhospholipase A2 Activates Hemostasis
BACKGROUND Phospholipases A(2) (PLA(2)) are aggressive enzymes that can destroy phospholipids of cell membranes. The resulting cell fragments trigger the kallikrein-mediated contact phase of coagulation. The aim of the present study was to expose citrated whole blood to PLA(2) and to quantify thrombin generation in recalcified plasma. METHODS Normal citrated blood was exposed to bovine pancre...
متن کاملAssaying phospholipase A2 activity.
Mammalian cells contain many structurally and functionally diverse phospholipases A2 (PLA2) that catalyze the hydrolysis of sn-2 fatty acid from membrane phospholipid. Assays are described for measuring the activity of Group IVA cytosolic PLA2alpha(cPLAalpha) and for secreted PLA2s (sPLA2) that are suitable for purified enzymes and for measuring activity in crude cell lysates and culture medium...
متن کاملPhospholipase A2 in cnidaria.
Phospholipase A2 (PLA2) is an enzyme present in snake and other venoms and body fluids. We measured PLA2 catalytic activity in tissue homogenates of 22 species representing the classes Anthozoa, Hydrozoa, Scyphozoa and Cubozoa of the phylum Cnidaria. High PLA2 levels were found in the hydrozoan fire coral Millepora sp. (median 735 U/g protein) and the stony coral Pocillopora damicornis (693 U/g...
متن کاملAnti-phospholipase A2 Receptor Antibody and Immunosuppression in Membranous Nephropathy: More Evidence for Pathogenicity of Anti-phospholipase A2 Receptor Autoantibodies.
In the 6 years since the discovery of anti-phospholipase A2 receptor (anti-PLA2R) antibodies in the majority of patients with primary membranous nephropathy (MN),1 our understanding of the role of anti-PLA2R in clinical disease has evolved rapidly. The initial small retrospective clinical studies indicated that anti-PLA2R levels could be modulated by immunosuppression.1,2 Levels decreased in ad...
