Peripheral blood leukocytes of three patients with Chédiak-Higashi syndrome (CHS) contained very low or undetectable levels of elastase, the major neutral protease in these cells. Likewise, peritoneal exudate leukocytes of beige mice (the murine counterpart of CHS) contained correspondingly reduced levels of their major neutral protease, a serine enzyme of mol wt 27,000. The elastase deficiency in CHS polymorphonuclear leukocytes might account in part for the high incidence of infections in these patients.
三名患有蔡迪二氏综合征(CHS)的患者外周血白细胞中,弹性蛋白酶(这些细胞中的主要中性蛋白酶)水平极低或无法检测到。同样,米色小鼠(CHS的鼠类对应物)的腹腔渗出白细胞中,其主要中性蛋白酶(一种分子量为27,000的丝氨酸酶)水平也相应降低。CHS多形核白细胞中的弹性蛋白酶缺乏可能部分解释了这些患者感染的高发生率。
