病毒对人们的生命构成极大的威胁。肠道病毒A71(EV-A71)感染世界各地的儿童和婴儿,迄今为止还没有FDA批准的治疗方法。了解病毒过程的基本机制有助于选择更有效的药物靶点,并设计更有效的抗病毒药物来阻止这种病毒。病毒RNA基因组的5′-非翻译区(5′-UTR)由三叶草结构和内部核糖体进入位点(IRES)组成。与三叶草结构结合的细胞蛋白调节病毒RNA合成,而与IRES结合的蛋白也称为IRES反式作用因子(ITAF)调节病毒翻译。在这篇综述中,我们调查了目前已知的细胞蛋白结合5′-UTR和影响病毒基因表达,重点比较蛋白质的功能和定位前和后(EV-A71)感染。全面了解宿主细胞的机制如何被病毒劫持和重新编程以促进其复制对于开发有效的抗病毒药物至关重要。
Viruses pose a great threat to people’s lives. Enterovirus A71 (EV-A71) infects children and infants all over the world with no FDA-approved treatment to date. Understanding the basic mechanisms of viral processes aids in selecting more efficient drug targets and designing more effective antivirals to thwart this virus. The 5′-untranslated region (5′-UTR) of the viral RNA genome is composed of a cloverleaf structure and an internal ribosome entry site (IRES). Cellular proteins that bind to the cloverleaf structure regulate viral RNA synthesis, while those that bind to the IRES also known as IRES trans-acting factors (ITAFs) regulate viral translation. In this review, we survey the cellular proteins currently known to bind the 5′-UTR and influence viral gene expression with emphasis on comparing proteins’ functions and localizations pre- and post-(EV-A71) infection. A comprehensive understanding of how the host cell’s machinery is hijacked and reprogrammed by the virus to facilitate its replication is crucial for developing effective antivirals.
