Abstract

The production of five prostanoids (PGD2, PGE2, PGF, 6-oxo-PGF, and TxB2) was examined after mast cell activation. Prostaglandin D2 (PGD2) was the major prostanoid produced after stimulation of rat peritoneal mast cells with the calcium ionophore A 23187, compound 48/80 or anti-rat IgE. The amount of PGD2 generated was not dependent on the quantity of histamine released. The time course of PGD2 production paralleled the release of histamine following activation with A 23187 or anti-rat IgE but with compound 48/80 release of histamine reached a maximum within 15 sec, whereas production of PGD2 was apparent only after 5 min and was still increasing at 30 min.
