摘要

摘要: 目的探究细胞因子信号转导抑制因子3（Suppressor of cytokine signaling 3, SOCS3）在流感病毒（Influenza virus）感染过程中对干扰素（Interferon, IFN）信号通路的调控作用。方法通过慢病毒感染的方式在人非小细胞肺癌细胞（A549细胞）中过表达SOCS3，利用siRNA技术在A549细胞中敲低SOCS3的表达，然后使用流感病毒感染SOCS3过表达或敲低的细胞系以及对照细胞系，于不同时间点收取RNA或蛋白样品，采用RT-PCR和Western blot技术检测干扰素信号通路中关键节点分子的表达或活化情况。结果检测发现细胞中过表达SOCS3后I型干扰素IFN-β和III型干扰素IL-28（Interleukin-28）、IL-29（Interleukin-29）表达水平下降，而敲低SOCS3表达后IFN-β及IL-28、IL-29的表达水平升高。进一步研究发现，过表达SOCS3对识别流感病毒RNA的模式识别受体视黄酸诱导基因-I（Retinoic acid-inducible gene 1, RIG-I）、黑色素瘤分化相关蛋白5（Melanoma differentiation-associated protein 5, MDA5）、Toll样受体3（Toll-like receptor 3, TLR3）以及干扰素调节因子7（Interferon regulatory factor 7, IRF7）的mRNA表达均有抑制作用。同时SOCS3还能影响干扰素下游信号转导与转录激活因子 1（Signal transducer and activator of transcription 1, STAT1）的活化，细胞中过表达SOCS3抑制流感病毒诱导的STAT1的磷酸化，而敲低SOCS3表达则使STAT1的磷酸化水平升高。结论流感病毒感染后，SOCS3能够在转录水平下调模式识别受体及干扰素调节因子的表达，抑制Ⅰ型和Ⅲ型干扰素的产生，同时还影响STAT1的活化从而阻断干扰素信号的传递。

Abstract: Objective Regulatory function of the suppressor of cytokine signaling 3 (SOCS3) in the interferon signaling pathway during an influenza virus infection on cells was studied. Method A549 cell lines were constructed with SOCS3 overexpression by a lentivirus infection and knockdown by siRNA technology. Along with control, they were infected with the influenza virus and sampled at times to assess the expressions and activation of crucial molecules within the interferon signaling pathway using RT-PCR and western blot analysis. Result Decreasing expressions of type I interferon IFN-β and type III interferons IL-28 and IL-29 were observed following the SOCS3 overexpression in cells. Conversely, the SOCS3 knockdown raised the expressions of IFN-β, IL-28, and IL-29. SOCS3 overexpression also suppressed the expressions of the interferon regulatory factor IRF7 as well as those of the pattern recognition receptors RIG-I, MDA5, and TLR3 responsible for detecting influenza virus RNA. The virus induced SOCS3 overexpression inhibited, but the knockdown enhanced, the STAT1 phosphorylation. Conclusion An influenza virus invasion on cells induced SOCS3 to recognize the receptors and regulate the mRNA expression inhibiting the type I and III interferon productions and STAT1 activation resulting in a blockage on the interferon signal transmission.
