| 摘 要： | 为了研究鳜IRAK4生物学特性及其在抗病毒免疫应答中的作用,根据鳜转录组数据中筛选出的IRAK4 unigene序列设计引物,利用SMART-RACE技术克隆得到CDS全长为1389 bp的c DNA(命名为Sc IRAK),编码462个氨基酸,含有1个N端死亡结构域和1个保守的中央蛋白激酶结构域。采用荧光定量RT-PCR方法分析了Sc IRAK4在健康鳜各组织中的表达差异及病毒感染后在脾脏中的表达变化,结果显示,健康鳜中Sc IRAK4在肝脏中表达量最大,与其他组织差异显著,而在血液、脑和胃中表达量最低;传染性脾肾坏死病毒(infectious spleen and kidney necrosis virus,ISKNV)感染鳜后Sc IRAK4的表达量呈现下调趋势,24 h脾脏中的表达量达到最低,为对照组的45%;而鳜弹状病毒(siniperca chuatsi rhabdovirus,SCRV)感染鳜后Sc IRAK4的表达量呈现上调趋势,12 h脾脏中Sc IRAK4的表达量达到最高,为对照组的8.17倍,表明Sc IRAK4在抗ISKNV和SCRV的免疫应答中可能发挥不同的作用。本研究为进一步揭示Sc IRAK4的抗病毒免疫反应机制提供了依据。
