Mouse bone marrow-derived mast cells (BMMC), stimulated with stem cell factor, IL-1β, and IL-10, secrete IL-6 and demonstrate a delayed phase of PGD2 generation that is dependent upon the induced expression of PG endoperoxide synthase (PGHS)-2. We have examined the potential for exogenous prostanoids, acting in a paracrine fashion, and endogenous prostanoids, acting in an autocrine fashion, to regulate PGHS-2 induction and IL-6 secretion in mouse BMMC. Exogenous PGE2, which acts through G protein-coupled receptors, and 15-deoxy-Δ12,14-PGJ2, which is a ligand for peroxisome proliferator-activated receptor (PPAR)γ, elicited a 2- to 3-fold amplification of PGHS-2 induction, delayed-phase PGD2 generation, and IL-6 secretion in response to stem cell factor, IL-1β, and IL-10. The effect of PGE2 was reproduced by the E prostanoid (EP)1 receptor agonist 17-trinor-PGE2, and the EP1/EP3 agonist, sulprostone, but not the EP2 receptor agonist, butaprost. Although BMMC express PPARγ, the effects of 15-deoxy-Δ12,14-PGJ2 were not reproduced by the PPARγ agonists, troglitazone and ciglitazone. PGHS-2 induction, but not IL-6 secretion, was impaired in cPLA2-deficient BMMC. However, there was no impairment of PGHS-2 induction in BMMC deficient in hematopoietic PGD synthase or PGHS-1 in the presence or absence of the PGHS-2 inhibitor, NS-398. Thus, although exogenous prostanoids may contribute to amplification of the inflammatory response by augmenting PGD2 generation and IL-6 secretion from mast cells, endogenous prostanoids do not play a role.
