We demonstrate here that the recently defined cytokine hepatocyte growth factor (HGF) 'primes' human neutrophils. Recombinant human HGF over the concentration range 0.1-20 ng/ml increased the neutrophil response to f-met-leu-phe by up to 200%, and required only a short preincubation, 10 min producing the maximum effect. Priming was independent of changes in cytosolic-free calcium homeostasis. We conclude that HGF may be a physiologically important cytokine with 'priming' activity for neutrophils.
我们在此证明,最近定义的细胞因子肝细胞生长因子(HGF)可“启动”人类中性粒细胞。浓度范围在0.1 - 20 ng/ml的重组人HGF可使中性粒细胞对f-甲硫-亮-苯丙氨酸的反应增强达200%,且仅需短暂预孵育,10分钟时产生最大效应。启动作用与胞质游离钙稳态的变化无关。我们得出结论,HGF可能是一种对中性粒细胞具有“启动”活性的重要生理细胞因子。
