microRNA(miRNA)在病毒与宿主相互作用中起着关键作用。本研究采用深度测序技术检测了H9 N2亚型禽流感病毒(AIV)感染鸡树突状细胞后细胞内miRNA的表达谱。共有66种已知的和36种新的miRNAs在H9 N2感染后有不同的表达,其中72种上调,30种下调。功能分析表明,这些miRNAs的预测靶点在胞吞、notch、溶酶体、p53、RIG-I-like和NOD-like受体信号通路中明显富集。这些结果为进一步研究miRNA在AIV致病和宿主防御反应中的作用提供了有价值的信息。
MicroRNA (miRNA) plays a key role in virus-host interactions. Here, we employed deep sequencing technology to determine cellular miRNA expression profiles in chicken dendritic cells infected with H9N2 avian influenza virus (AIV). A total of 66 known and 36 novel miRNAs were differently expressed upon H9N2 infection, including 72 up-regulated and 30 down-regulated miRNAs. Functional analysis showed that the predicted targets of these miRNAs were significantly enriched in several pathways including endocytosis, notch, lysosome, p53, RIG-I-like and NOD-like receptor signaling pathways. These data provide valuable information for further investigating the roles of miRNA in AIV pathogenesis and host defense response.
