摘要
采用生物活性测定法和免疫细胞化学染色法.观察了内毒素诱导正常人单核细胞产生白细胞介素(?).白细胞介素6和肿瘤环死因子的动态过程.以及彼此之间的相互关系。结果表明,三种细胞因子的胞浆内累积和释放均有各自不同的时相变化.反映出这三种细胞因子基因活化、转录、翻译和释放过程的差异.此外.仅部分单核细胞合成这三种细胞因子.
Kinetics of production of IL-1, IL-6 and TNFa induced by endotoxin from human monocytes as well as their relationships were studied using cytokine bioassays and immu nocytochemical staining methods. The results showed that accu mulation of IL-1 β, IL-6 and TNFa molecules in cytoplasma and their release into supernatants had different kinetic patterns from each others, reflecting the difference in gene activation, transcription, translation and release of these three cytokines. In addition, only part of monocytes synthesize IL-1 β, IL-6 and TNFα, suggesting the presence of different cytokineproducing monocyte subsets.
