Secretory phospholipase A(2) (sPLA(2)) produces lipids that stimulate polymorphonuclear neutrophils (PMNs). With the discovery of sPLA(2) receptors (sPLA(2)-R), we hypothesize that sPLA(2) stimulates PMNs through a receptor. Scatchard analysis was used to determine the presence of a sPLA(2) ligand. Lysates were probed with an antibody to the M-type sPLA(2)-R, and the immunoreactivity was locali...
In order to be properly divisible, the cell membrane has to be remodeled and intracellular membranes must be converted into a vesiculated state prior to mitosis. Phospholipases A2, C, and D (PLA2, PLC, and PLD) are involved in regulatory events of intracellular mitogen signaling pathways. We describe here three methods for comprehensively assaying those phospholipases: 1) in vitro microassays, ...
Several genes have been related to late-onset Alzheimer's disease (LOAD). Phospholipases A2 (PLA2) influence the processing and secretion of the amyloid precursor protein, which gives rise to the beta-amyloid peptide, the major component of the amyloid plaque in AD. Hence, in the present study, polymorphisms of three genes encoding PLA2 enzymes group (cytosolic PLA2: BanI cPLA2 polymorphism; ca...
PURPOSE Systemic hypertension is a risk factor for age-related neovascular retinal diseases. The major condition that induces hypertension is the intake of dietary salt (NaCl) resulting in increased extracellular osmolarity. High extracellular NaCl was has been shown to induce angiogenic factor production in RPE cells, in part via the transcriptional activity of nuclear factor of activated T ce...
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...
Phospholipases A2 (PLA2) are a group of enzymes that hydrolyze phospholipids at the sn-2 position, being present in all nature. In venomous animals, these proteins assume a special role, being able to exert diverse pharmacological effects. In this work, authors identified a new isoform of PLA2 in the venom of Porthidium hyoprora, which was isolated through sequential chromatographic steps and n...
