Kolko, Christoffersen, Varoqui, Bazan: Expression and induction of secretory phospholipase A2 group IB in brain. dans Cellular and molecular neurobiology 2006
The sPLA2 (Montrer PLA2G2A Anticorps) IB-PLA2R (Montrer PLA2R1 Anticorps) interaction stimulated podocyte apoptosis through activating ERK1/2 and cPLA2alpha (Montrer PLA2G4A Anticorps) and through increasing the podocyte AA content
TNF-alpha (Montrer TNF Anticorps)-induced cPLA2 (Montrer PLA2G4A Anticorps) expression and PGE2 release were mediated through a Jak2 (Montrer JAK2 Anticorps)/PDGFR (Montrer PDGFRB Anticorps)/PI3K (Montrer PIK3CA Anticorps)/Akt (Montrer AKT1 Anticorps)/p42/p44 (Montrer PSMC6 Anticorps) MAPK (Montrer MAPK3 Anticorps)/Elk-1 (Montrer ELK1 Anticorps) pathway in human lung epithelial cells.
stimulation of three isoforms of PLA2 by thapsigargin liberates free AA that, in turn, induces capacitative calcium influx in human T-cells
results indicate a selective sorting of a cell-derived cPLA2 (Montrer PLA2G4A Anticorps) during human cytomegalovirus maturation, which is further required for infectivity
Group IB phospholipase A2 (PLA2G1B) stimulates leukotriene B4 (LTB4 (Montrer PTGR1 Anticorps)) production in the absence of cytochalasin B in human neutrophils.
Here, we report sPLA2 (Montrer PLA2G2A Anticorps)-IB in rat and human brain as well as in neurons in primary culture. The distribution of sPLA2 (Montrer PLA2G2A Anticorps)-IB seems to be mainly neuronal, with the highest abundance occurring in the cerebral cortex and hippocampus.
a critical regulatory role of arachidonate reacylation that limits leukotriene biosynthesis in concert with 5-lipoxygenase (Montrer ALOX5 Anticorps) and cytosolic phospholipase A (Montrer HRASLS Anticorps)(2)alpha activation
Results describe the structural basis for bile salt inhibition of pancreatic phospholipase A2.
MMP-2 (Montrer MMP2 Anticorps)/9 production is regulated by sPLA2 (Montrer PLA2G2A Anticorps)-IB acting as a receptor ligand to activate cPLA2 (Montrer PLA2G4A Anticorps)
Equilibrium unfolding of porcine pancreatic phospholipase A2 was monitored using multiple approaches. An unusually broad unfolding transition at remarkably high denaturant concentration was observed.
Porcine group IB secretory phospholipase A2 (PLA2G1B) stimulates the expression and secretion of CXC chemokine (Montrer CXCL12 Anticorps) ligand 8 (Montrer CCL8 Anticorps) (CXCL8 (Montrer IL8 Anticorps)) in human neutrophils without affecting other proinflammatory cytokines.
Porcine pancreatic PLA(2) shows a long lag (Montrer STMN1 Anticorps) phase of several hours during which the enzyme binds to the bilayer surface, but only 5+/-3% of the lipids react before the onset of rapid hydrolysis.
Results show that the decylsulfate epitope for the successive E i (#) complexes increasingly resembles the micellar complex formed by the binding of PLA2 to preformed micelles.
An increased sPLA(2 (Montrer PLA2G2A Anticorps)) activity and a reduced inhibition may play an important role in the pathogenesis of ischemia-reperfusion injury of non-heart-beating donor liver grafts.
Interfacial activation of pig pancreatic IB phospholipase A (Montrer HRASLS Anticorps)(2) (PLA2) is modeled in terms of the three discrete premicellar complexes (E(i)(#), i = 1, 2, or 3) consecutively formed by the cooperative binding of a monodisperse amphiphile to the i-face
Phospholipase A2 isoforms are differentially regulated; they selectively participate in retinal signaling in an experimental model of age-related macular degeneration.
results suggest the hydrophobic surfactant protein, SP-B, protects alveolar surfactant phospholiopids from hydrolysis mediated by multiple sPLA(2 (Montrer PLA2G2A Anticorps)) in both vesicles (alveolar subphase) and monomolecular films (air-liquid interface)
crystal structure of the triple mutant pancreatic phospholipase A2 with calcium.
NMR characterization of a unique low-barrier hydrogen bond between an active site residue from the enzyme and a bound inhibitor: the complex between secreted phospholipase A (Montrer HRASLS Anticorps)(2) (sPLA(2 (Montrer PLA2G2A Anticorps)), from bovine pancreas) and a transition-state analog inhibitor HK32
The final protein model consists of 123 amino-acid residues, two calcium ions, one chloride ion, 243 water molecules and six 2 (Montrer SIX2 Anticorps)-methyl-2,4-pentanediol molecules.
The crystal structure of the triple mutant (K53,56,121M) of bovine pancreatic phospholipase A2 complexed with an organic molecule, p-methoxybenzoic acid (anisic acid), is reported.
The quadruple mutant of phospholipase A2 has monoclinic or trigonal crystal structures and results suggested evidence for the involvement of the second calcium and surface loop in interfacial binding.
Pla2g1b inactivation suppressed diet-induced body weight gain and reduced diabetes and atherosclerosis in LDL receptor (Montrer LDLR Anticorps)-deficient mice.
inhibition of Pla2g1b protects against diet-induced hyperlipidemia
Lysophospholipids produced by Pla2g1b hydrolysis suppress hepatic fat utilization and down-regulate energy expenditure, preventing metabolically beneficial adaptation to a high-fat diet exposure in promoting diet-induced obesity and type 2 diabetes.
sPLA2IB has a role in promoting MMP-2 (Montrer MMP2 Anticorps) mediated cell migration via the phosphatidylinositol 3-kinase and Akt (Montrer AKT1 Anticorps) pathway
Elevating plasma lysophospholipid levels in Pla2g1b deficient mice via intraperitoneal injection resulted in glucose intolerance.
pro-inflammatory effects of Ps. aeruginosa involve release of an sPLA2 of epithelial origin that, in part, via distinct signalling molecules, transactivates the ABCA1 gene, leading to export of phospholipid.
The results indicate that PLA2 activity in equine endometrium changes with the stage of the oestrous cycle and thus may be influenced by systemic hormone concentrations.
During pregnancy, PLA2 expression may be sufficient to initiate the cascade for prostaglandin f2alpha secretion and does not play a direct role in maternal recognition of pregnancy.
Phospholipase A2 (EC 220.127.116.11) catalyzes the release of fatty acids from glycero-3-phosphocholines. The best known varieties are the digestive enzymes secreted as zymogens by the pancreas of mammals. Sequences of pancreatic PLA2 enzymes from a variety of mammals have been reported. One striking feature of these enzymes is their close homology to venom phospholipases of snakes. Other forms of PLA2 have been isolated from brain, liver, lung, spleen, intestine, macrophages, leukocytes, erythrocytes, inflammatory exudates, chondrocytes, and platelets (Seilhamer et al., 1986
