title: Ionophore-stimulated rat basophilic leukemia cells produce PAF-acether.
abstract: Ionophore (A23187) stimulated rat basophilic leukemia (RBL-1) cells produce a lipid mediator which caused rabbit platelets to aggregate and which by using platelet-activating factor (PAF)-acether antagonists and high-pressure liquid chromotography was shown to be PAF-acether. Thus RBL-1 cells represent a cell type suitable for studying the coordinated release of three mediators of anaphylaxis: histamine, leukotrienes C4/D4 (slow-reacting substances) and PAF-acether.
