Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a predictor biomarker for incident atherosclerotic disease. Lp-PLA2 has been identified in atherosclerotic plaques, however, its role in atherosclerosis is still under investigation. Lp-PLA2 belongs to the superfamily of phospholipase A2 enzymes. It is produced by macrophages that appears to play a role in the atherosclerotic vessel wall. Eme...
In preparations of synaptic terminals (synaptosomes) isolated from rat brain, the activity of phospholipase A2 (PLA2), a phospholipid hydrolase that serves a central function in signal transduction, was inhibited in a Ca(2+)-dependent manner by incubation with 60 mM K+ or with the Ca(2+)-selective ionophore ionomycin. Reversal by alkaline phosphatase treatment suggested that this inhibitory eff...
BACKGROUND Lipoprotein-associated phospholipase A2 (Lp-PLA2) plays complex and adverse roles on atherosclerosis. Current study was to investigate whether increased plasma Lp-PLA2 level is independently associated with the severity of coronary artery diseases (CAD). METHODS Totally 781 participants were enrolled and performed coronary angiography (CAG) to figure out the number of coronary arte...
Human group IIa phospholipase A2 (hIIa-PLA2) is a highly basic protein that is secreted from a number of cells during inflammation and may play a role in arachidonate liberation and in destruction of invading bacteria. It has been proposed that rodent group IIa PLA2 is anchored to cell surfaces via attachment to heparan sulfate proteoglycan and that this interaction facilitates lipolysis. hIIa-...
BACKGROUND Measuring C-reactive protein (CRP) has been recommended to identify patients at high risk for coronary heart disease (CHD) with low LDL cholesterol (LDL-C). Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a proinflammatory enzyme associated primarily with LDL. METHODS AND RESULTS In a prospective, case cohort study in 12 819 apparently healthy middle-aged men and women in the ...
gte vml 1]> چکیده زمینه و هدف: ترومبوآمبولی وریدی (vte) از علل مهم مرگ و میر در جوامع مختلف بشری است. فاکتور 5 لیدن (fvl)، پلی مورفیسم c677t در متیلن تتراهیدروفولات ردوکتاز (mthfr) و پلی مورفیسم a2 از گلیکوپروتئین iib/iiia پلاکتی از عوامل مهم خطرزای ارثی در ترومبوآمبولی وریدی است. از آن جا که اطلاعات معدودی از هموزیگوت ها در دست است، هدف از مطالعه حاضر بررسی همراهی حالت هموزیگوت پلی مورفیسم های...
Description Background: The phospholipase A2 (PLA2s) superfamily, consisting of at least 34 members subdivided into at least 15 groups, is a group of intracellular and secreted enzymes that hydrolyzes the sn-2 ester bond in glycerophospholipids found in lipoproteins and cellular membranes to liberate fatty acids and lysophospholipids that can act as intracellular second messengers or are furthe...
We describe the interaction of various phospholipases A2 (PLA2) from snake venoms of the family Viperidae (Macrovipera lebetina obtusa, Vipera ursinii renardi, Bothrops asper) with giant unilamellar vesicles (GUVs) composed of natural brain phospholipids mixture, visualized through fluorescence microscopy. The membrane fluorescent probes 8-anilino-1-naphthalenesulfonicacid (ANS), LAUDRAN and PR...
The development of atherosclerotic vascular disease is invariably linked to the formation of bioactive lipid mediators and accompanying vascular inflammation. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an enzyme that is produced by inflammatory cells, co-travels with circulating low-density lipoprotein (LDL), and hydrolyzes oxidized phospholipids in LDL. Its biological role has been c...
INTRODUCTION Lipoprotein-associated phospholipase A2 (Lp-PLA2) and homocysteine (Hcy) have been linked to inflammation and Alzheimer's disease (AD). Using a case-control design, we examined their independent effects and interactions with cardiovascular disease equivalent (CVDE), on AD risk. METHODS AD cases and controls were from the Texas Alzheimer's Research and Care Consortium study. Lp-PL...
