小鼠骨髓来源的肥大细胞(BMMC)在干细胞因子、白细胞介素 - 1β和白细胞介素 - 10刺激下分泌白细胞介素 - 6,并呈现出前列腺素D2(PGD2)生成的延迟期,该延迟期依赖于前列腺素内过氧化物合酶(PGHS) - 2的诱导表达。我们已经研究了以外分泌方式起作用的外源性前列腺素和以内分泌方式起作用的内源性前列腺素在调节小鼠BMMC中PGHS - 2诱导和白细胞介素 - 6分泌方面的可能性。通过G蛋白偶联受体起作用的外源性前列腺素E2(PGE2)以及作为过氧化物酶体增殖物激活受体(PPAR)γ配体的15 - 脱氧 - Δ12,14 - 前列腺素J2,在干细胞因子、白细胞介素 - 1β和白细胞介素 - 10刺激下,使PGHS - 2诱导、延迟期PGD2生成以及白细胞介素 - 6分泌增强了2 - 3倍。PGE2的作用可由E类前列腺素(EP)1受体激动剂17 - 去甲 - PGE2以及EP1 / EP3激动剂舒前列酮重现,但不能由EP2受体激动剂布他前列素重现。尽管BMMC表达PPARγ,但15 - 脱氧 - Δ12,14 - 前列腺素J2的作用不能由PPARγ激动剂曲格列酮和西格列酮重现。在胞质型磷脂酶A2(cPLA2)缺陷的BMMC中,PGHS - 2诱导受损,但白细胞介素 - 6分泌不受影响。然而,在有或没有PGHS - 2抑制剂NS - 398的情况下,造血前列腺素D合酶或PGHS - 1缺陷的BMMC中PGHS - 2诱导没有受损。因此,尽管外源性前列腺素可能通过增加肥大细胞中PGD2生成和白细胞介素 - 6分泌来促进炎症反应的放大,但内源性前列腺素不起作用。
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.
