Modulation of lipid and protein mediators of inflammation by cytosolic phospholipase A2alpha during experimental sepsis.

Abstract excerpt

Cytosolic phospholipase A(2)alpha (cPLA(2)alpha) is one of the key enzymes in lipid mediator generation. It preferentially hydrolyzes arachidonoyl-phospholipid in response to cellular stimuli, liberating arachidonic acid, the shared precursor of PGs and leukotrienes. Mice with disruption of the cPLA(2)alpha gene exhibit a more than 80% decrease in the generation of these lipid mediators, leading to dramatic...
