本报告描述了使用新的荧光Ca2+螯合剂Indo-1 AM在多形核白细胞(PMN)中由化学引诱剂诱导的细胞质游离钙水平(Ca2+i)的增加。流式细胞术检测胞浆内Ca2+的升高。通过这种方法,发现98%的PMN对F-Met-Leu-Phe (FMLP)和白三烯B4 (LTB4)刺激有反应。虽然这两种物质都能诱导Ca2+i快速且相对均匀的升高,但只有FMLP能使Ca2+i持续升高,而LTB4诱导的Ca2+i升高是短暂的。此外,广角光散射和电子细胞体积测量的结合使用允许分析总外周血细胞群中的Ca2+i变化。人纤维组织细胞瘤细胞系(GCT)的上清能够增加PMN中Ca2+的释放。这种活性可能归因于一种新的粒细胞活化因子,因为在该上清中存在的人重组白细胞介素-1 α (IL-1 α)、粒细胞集落刺激因子(G-CSF)和粒细胞-巨噬细胞集落刺激因子(GM-CSF)都不能诱导PMN中的Ca2+i升高。
The present report describes the increase in cytosolic-free calcium levels (Ca2+i) induced by chemoattractants in polymorphonuclear leukocytes (PMN) using the new fluorescent Ca2+ chelator Indo-1 AM. Increases in cytosolic Ca2+ were measured by flow cytometry. With this approach, 98% of PMN were found to respond to F-Met-Leu-Phe (FMLP) and leukotriene B4 (LTB4) stimulation. Although both substances induced a rapid and relatively homogeneous rise in Ca2+i, only FMLP gave a sustained Ca2+i rise, whereas that induced by LTB4 appeared transient. In addition, the combined use of wide-angle light scatter and electronic cell volume measurement allowed analysis of Ca2+i variations in the total peripheral blood cell population. The supernatant of a human fibrous histiocytoma cell line (GCT) was able to increase Ca2+ release in PMN. This activity may be ascribed to a new granulocytic activation factor, as neither human recombinant interleukin-1 alpha (IL-1 alpha), granulocyte-colony stimulating factor (G-CSF), nor granulocyte-macrophage-colony stimulating factor (GM-CSF), which were present in this supernatant, were able to induce a Ca2+i rise in PMN.
