Exogenous phospholipases have been used extensively as tools to study the role of membrane lipids in receptor mechanisms. We used in vitro quantitative autoradiography to evaluate the effect of phospholipase A2 (PLA2) on N-methyl-D-aspartate (NMDA) and non-NMDA glutamate receptors in rat brain. PLA2 pretreatment induced a significant increase in alpha-[3H]amino-3-hydroxy-5-methyl-isoxazole-4-pr...

We report on a secretory phospholipase A2 (sPLA2) associated with membrane-enriched fractions prepared from hemocytes of the tobacco hornworms, Manduca sexta. Virtually no PLA2 activity was detected in serum of immunologically naive or bacterially challenged hornworms. PLA2 activity was detected in cytosolic and membrane-enriched fractions prepared from hemocytes. PLA2 activity in the cytosolic...

OBJECTIVE Although prior studies report a relationship between elevated lipoprotein-associated phospholipase A2 (Lp-PLA2) and incident cardiovascular disease, the prospective association of Lp-PLA2 with incident peripheral arterial disease (PAD) has not been studied. We investigated the association between Lp-PLA2 mass and activity and the risk of developing clinical PAD and low ankle-brachial ...

Confluent, primary cultures of mouse embryo palate mesenchyme (MEPM) cells are refractory to activation of phospholipase A2 (PLA2) by the calcium ionophore A23187. However, treatment of these cultures with epidermal growth factor (EGF) permits the cells to activate PLA2 in response to A23187. We have developed this finding by exploring molecular mechanisms by which growth factors modulate mobil...

The Transient Receptor Potential Canonical 5 (TRPC5) protein forms calcium-permeable cationic channels that are stimulated by G protein-coupled receptor agonists. The signaling pathways of such agonist effects are poorly understood. Here we investigated the potential for involvement of lysophosphatidylcholine (LPC) and arachidonic acid generated by group 6 (GVI) phospholipase A2 (PLA2) enzymes,...

We previously showed that group II phospholipase A2 (PLA2-II), a secretory, bactericidal, and proinflammatory protein in intestinal crypts, is upregulated after lipopolysaccharide (LPS) and platelet-activating factor (PAF) challenge. Here we examined whether germ-free environment (GF) or antibiotic treatment (ABX) affects the pathophysiological responses and intestinal PLA2-II activity after PA...

Lipoprotein associated phospholipase A2 (Lp-PLA2) overexpression is implicated in athero-sclerosis. In the present study, we evaluated the effects of lentiviral-mediated RNA interference (RNAi) of Lp-PLA2 on inflammation and atherosclerosis in apolipoprotein E-deficient mice. Apolipoprotein E-deficient mice were randomly allocated to control and experimental ...

Members of the secreted phospholipase A2 (PLA2) protein family can inhibit HIV-1 virus replication in vitro. To evaluate the impact of PLA2 gene polymorphisms on AIDS disease development, we studied 12 family members using SNPlextrade mark technology that permitted simultaneous typing of 70 tagging Single Nucleotide Polymorphisms (tagSNPs). The study utilized HIV-1 seropositive donors with slow...

Objective—Lipoprotein-associated phospholipase A2 (Lp-PLA2) may be a new and independent predictor of cardiovascular events. The effect of Lp-PLA2 may be exerted through effects of the enzyme on the development of atherosclerosis. Therefore, we investigated the association between Lp-PLA2 activity and measures of extracoronary atherosclerosis. Methods and Results—Lp-PLA2 activity was determined...

Phospholipase A2 (PLA2) catalyses the hydrolysis of phospholipids into lysophospholipids and free fatty acids. Physiological studies have indicated that PLA2 is involved in stomatal movement. However, genetic evidence of a role of PLA2 in guard cell signalling has not yet been reported. To identify PLA2 gene(s) that is (are) involved in light-induced stomatal opening, stomatal movement was exam...
