title: Dissociate arachidonic acid release from eicosanoid synthesis in rat peritoneal macrophages is possible using concomitantly eicosapentanoic acid as a phospholipid analogue.
abstract: Activated macrophages exposed to the association of eicosapentanoic acid 20:5 n-3 and a synthetic non hydrolysable phospholipid analogue maintained a discrete synthesis of active eicosanoids. 20:4 n-6 split from the internalized 20:4-GPC was accumulated in cells and extracellular fluids. This combination thus represents a novel approach to reduce the 20:4 n-6 cascade.
