IL-6可由多种不同的细胞产生,也称作为IFN β_2、B细胞刺激因子2、杂交瘤生长因子、肝细胞刺激因子,为26KDa 蛋白质。已知它具有抗病毒、诱发急性期蛋白、刺激B 细胞分化、辅助人类T 细胞活化的功能。本文表明IL 6还能增强NK 细胞的活性。作者首先观测了IL-6对人NK 细胞活性的影响。以去除粘附细胞的PBL 做为NK 细胞的来源,NK 细胞与天然或重组IL-6在 IL-6 can be produced by a variety of different cells, also known as IFN [beta] 2, B-cell stimulator 2, hybridoma growth factor, hepatocyte stimulating factor, a 26 kDa protein. It is known to have the function of antivirus, inducing acute phase proteins, stimulating B cell differentiation, and assisting the activation of human T cells. This article shows that IL 6 also enhances NK cell activity. The authors first observed the effects of IL-6 on human NK cell activity. To remove adherent cell-derived PBL as a source of NK cells, NK cells were incubated with native or recombinant IL-6
