人类肠病毒71型(EV71)是手足口病(HFMD)的主要病原体,与婴幼儿严重的神经系统疾病甚至死亡有关。EV71型人中枢神经系统感染的发病机制尚不清楚。在本研究中,采用人全基因组芯片对感染EV71的SH-SY5Y人神经母细胞瘤细胞进行转录组分析。结果表明,EV71感染导致161个人mrna表达改变,其中上调基因74个,下调基因87个。生物信息学分析表明,差异调节的mrna可能在选定的途径中发挥作用,包括细胞周期/增殖、细胞凋亡和细胞因子/趋化因子反应。最后,使用实时RT-PCR对微阵列结果进行验证,具有较高的识别性。总之,我们的研究结果提供了宿主对人神经母细胞瘤细胞EV71感染反应的基本信息,这一发现将有助于解释EV71感染的发病机制和病毒-宿主相互作用。
Human enterovirus type 71 (EV71) is the major pathogen of hand-foot-and-mouth disease (HFMD) and has been associated with severe neurological disease and even death in infants and young children. The pathogenesis of EV71 infection in the human central nervous system remains unclear. In this study, human whole genome microarray was employed to perform transcriptome profiling in SH-SY5Y human neuroblastoma cells infected with EV71. The results indicated that EV71 infection lead to altered expression of 161 human mRNAs, including 74 up-regulated genes and 87 down-regulated genes. Bioinformatics analysis indicated the possible roles of the differentially regulated mRNAs in selected pathways, including cell cycle/proliferation, apoptosis, and cytokine/chemokine responses. Finally, the microarray results were validated using real-time RT-PCR with high identity. Overall, our results provided fundamental information regarding the host response to EV71 infection in human neuroblastoma cells, and this finding will help explain the pathogenesis of EV71 infection and virus-host interaction.
