嗜酸性粒细胞是一类颗粒状白细胞,在许多炎症过程中都很突出,特别是在哮喘、某些过敏性疾病和寄生虫感染期间。在与钙离子载体A23187(参考文献1-4)(一种绕过膜钙门控制机制的非生理性试剂5)孵育后,嗜酸性粒细胞产生大量的硫多肽白三烯,这是平滑肌收缩的有效诱导剂6 - 9和粘液产生10。现在已知这些物质代表了先前称为“过敏反应慢反应物质”(SRS-A)的活性,但试图确定嗜酸性粒细胞产生SRS-A的生理刺激迄今尚未成功。这些细胞含有IgG (Fc) 11-14的识别受体,已知它们粘附在大型生物(如蠕虫幼虫)的表面,并可通过接触被激活。我们在这里表明,嗜酸性粒细胞,特别是当被激活时,在与涂有IgG的大颗粒接触后产生硫肽白三烯。
Eosinophils, a class of granular leukocytes, are prominent in many inflammatory processes, particularly in asthma, certain allergic diseases and during infections with helminthic parasites. Following incubation with the Ca ionophore A23187 (refs 1–4) (a non-physiological agent which circumvents membrane calcium-gating mechanisms5), eosinophils generate large amounts of sulphidopep-tide leukotrienes, potent inducers of smooth muscle constriction6–9 and mucus production10. These are now known to represent the activity previously termed ‘slow-reacting substance of anaphylaxis’ (SRS-A) but attempts to identify a physiological stimulus for SRS-A production by eosinophils have so far been unsuccessful. The cells contain recognized receptors for IgG (Fc)11–14 and it is known that they adhere to, and can be activated by, contact with the surface of large organisms such as helminthic larvae15. We show here that eosinophils, particularly when activated, produce sulphidopeptide leukotrienes after contact with large particles coated with IgG.
