Chemotactic factors induce neutrophil emigration into tissues. Interleukin-1 (IL-1) was found to be several log times more potent in this respect than C5a des Arg, leukotriene B4, and f-Met-Leu-Phe and of comparable potency to endotoxin. Kinetic studies revealed a rapid and transient neutrophil influx, with the peak rate at 30-90 minutes. Cross tachyphylaxis was observed between IL-1 and endotoxin; and this, together with its high potency and rapid onset of action, suggest that IL-1 mediates endotoxin-induced neutrophil emigration.
趋化因子诱导中性粒细胞向组织内游走。白细胞介素-1(IL-1)在这方面的效力比C5a去精氨酸、白三烯B4和f-甲硫氨酰-亮氨酰-苯丙氨酸强几个对数级,与内毒素的效力相当。动力学研究显示中性粒细胞快速且短暂地流入,峰值速率出现在30 - 90分钟。在IL-1和内毒素之间观察到交叉快速耐受性;这一点,连同其高效力和快速起效,表明IL-1介导内毒素诱导的中性粒细胞游走。
