白细胞介素6 (IL6)是一组细胞因子的新定义,如B细胞刺激因子2 (BSF‐2)、杂交瘤浆细胞瘤生长因子(HGF)、干扰素β2 (IFN‐β2)、肝细胞刺激因子(HSF)等。最近有研究表明,IL - 6可能是急性期蛋白反应的主要介质,而IL - 1β和TNF - α可能起次要作用。我们通过体内和体外实验比较了三种细胞因子对肝脏蛋白合成的影响。将人肝癌细胞(PLC/PRFS)分别暴露于每种细胞因子20 h,然后在蛋白和RNA水平上研究其作用。这三种细胞因子均可减少白蛋白,增加C3和铜蓝蛋白的生物合成。细胞因子在RNA水平上诱导了相同的效果,表明这种调节是翻译前的。由于肌动蛋白基因的表达没有改变,细胞因子的作用是特异性的;此外,这种作用被针对细胞因子的特异性抗体阻断。单个细胞因子的作用是剂量和时间依赖的,并且在数量上具有可比性。没有一种细胞因子能够改变α 1 -抗胰蛋白酶的合成。小鼠体内实验表明,IL - 1β和TNF - a均可诱导小鼠肝脏血清淀粉样蛋白a (SAA) mRNA表达,并增加B因子(Bf)基因表达。人重组il - 6诱导SAA基因表达,对Bf基因表达也有微弱的正向影响。这些数据表明,所研究的三种细胞因子在数量和质量上具有可比性,并且这三种细胞因子都可能参与急性期蛋白反应。
Interleukin 6 ( IL6 ) is the new definition of a group of cytokines previously named according to their biological activity, e.g. B cell stimulatory factor 2 (BSF‐2), hybridoma plasmocytoma‐growth factor (HGF), interferon‐β2 (IFN‐β2), hepatocyte stimulating factor (HSF). It has recently been suggested that IL6 may represent the major mediator of actue‐phase protein response whereas IL 1β and TNF‐α could play a minor role. We compared the effect of the three cytokine on hepatic protein synthesis by performing in vitro as well as in vivo experiments. Human hepatoma cells (PLC/PRFS) were exposed to each cytokine separately for 20 h, and the effect was then studied at the protein and RNA level. All three cytokines reduced albumin and increased C3 and ceruloplasmin biosynthesis. The cytokines induced the same effect at the RNA level indicating that the modulation was pretranslational. The effect of the cytokines was specific since actin gene expression was not changed; furthermore the effect was blocked by specific antibodies against the cytokines. The effect of the single cytokines was dose and time dependent, and quantitatively comparable. None of the cytokines was able to alter αl‐anti‐trypsin synthesis. In vivo experiments with mice showed that IL 1β and TNF‐a both induce serum amyloid A (SAA) mRNA in the mouse liver and increase factor B (Bf) gene expression. Human recombinant IL6 induced SAA gene expression and it also had a weak positive effect on Bf gene expression after i.p. injection. These data demonstrate that the three cytokines studied are quantitatively and qualitatively comparable, and that all three are probably involved in acute‐phase protein response.
