WebMar 3, 2006 · Abstract Phagocytosis of non-opsonized microorganisms by macrophages initiates innate immune responses for host defense against infection. Cytosolic phospholipase A (2) is activated during phagocytosis, releasing arachidonic acid for production of eicosanoids, which initiate acute inflammation. WebCytosolic phospholipase A2 is an enzyme that in humans is encoded by the PLA2G4A gene. [5] [6] Function [ edit] This gene encodes a member of the cytosolic phospholipase A2 group IV family. The enzyme catalyzes the hydrolysis of membrane phospholipids to release arachidonic acid which is subsequently metabolized into eicosanoids.
