Abstract

The effect of the calcium ionophore A23187 on the release and metabolism of [3H]arachidonic acid was examined in normal polymorphonuclear leukocytes and those obtained from patients with chronic granulomatous disease. The ionophore A23187 which stimulates oxidative metabolism in normal polymorphonuclear leukocytes was ineffective in increasing oxidative metabolism (chemiluminescence) in polymorphonuclear leukocytes from patients with chronic granulomatous disease. However, the ionophore A23187 stimulated the release of [3H]arachidonic acid from chronic granulomatous disease neutrophil phospholipids and stimulated its metabolism into hydroxyeicosatetraenoic acids and leukotrienes.

摘要

在正常多形核白细胞以及从慢性肉芽肿病患者体内获取的多形核白细胞中,研究了钙离子载体A23187对[3H]花生四烯酸释放和代谢的影响。钙离子载体A23187可刺激正常多形核白细胞的氧化代谢,但对增加慢性肉芽肿病患者多形核白细胞的氧化代谢(化学发光)无效。然而,钙离子载体A23187可刺激慢性肉芽肿病中性粒细胞磷脂释放[3H]花生四烯酸,并刺激其代谢生成羟基二十碳四烯酸和白三烯。
