添加低浓度的佛波醇12-肉豆蔻酸酯13-乙酸酯到兔中性粒细胞诱导细胞聚集,脱粒,增加耗氧量和增加与细胞骨架相关的肌动蛋白的量,而不增加细胞内游离钙的水平,如使用荧光探针quin-2测量。佛波醇12-肉豆蔻酸酯13-乙酸酯启动中性粒细胞反应的能力与趋化因子产生的反应相似,但不引起细胞内游离钙水平的升高,这表明有两种可能性;除了钙外,还有第二信使,或者它在钙动员的远端激活细胞。甘油二酯在中性粒细胞活化中的可能作用进行了讨论。
The addition of low concentrations of phorbol 12-myristate 13-acetate to rabbit neutrophils induces cell aggregation, degranulation, increased oxygen consumption and an increase in the amount of actin associated with the cytoskeleton without a rise in the level of intracellular free calcium as measured using the fluorescent probe quin-2. The ability of phorbol 12-myristate 13-acetate to initiate neutrophil responses similar to those produced by the chemotactic factor without causing a rise in the level of intracellular free calcium suggests two possibilities; that there is a second messenger in addition to calcium or that it activates the cells at a point distal to calcium mobilization. The possible role of diacylglycerol in neutrophil activation is discussed.
