项目摘要
During the period(April, 2008.March 2012) of this grant, we clarified several new mechanisms on the hemagglutinin(HA) mutations responsible for the binding of highly pathogenic influenza virus(H5N1 subtype) to human type receptors and got progress on the drug discovery for influenza.(1) We identified several type of amino acid substitutions in the HA(H5) spike of highly pathogenic avian influenza viruses(H5N1 subtype) isolated from not only "patients" but also from "birds" that increase their human-type receptor(Neu5Acα2, 6Gal) specificity Viruses in those sublineages exhibited increased attachment and infectivity in the human respiratory tract. We also identified an experimental reassortant H5 HA/H1N1 virus. comprising H5 HA(from an H5N1 virus) with only four amino acid mutations and the remaining seven gene segments from a 2009 pandemic H1N1 virus. that exhibited increased attachment to the human type receptor and was capable of "droplet transmission in a ferret model". Our findings may help to advance our understanding of the mechanisms and evolutionary pathways that contribute to avian influenza virus transmission in mammals.(2) We also determined the fine chemical structures of H5N1 viral HA receptor N-linked sialo sugar chains of several target cells of H5N1 host animals, such as pig, dog, cat, embryonated chicken eggs.(3) We developed more than 15 new synthetic and native compounds which inhibit human influenza virus receptor binding, replication and budding from the infected host cells.
在这笔赠款的期间(2008年4月。2012年3月),我们阐明了导致高度致病性影响病毒(H5N1亚型)与人类类型受体结合的几种新机制(HA)突变的突变,并在药物发现上对影响力的药物发现取得了进展。病毒(H5N1亚型)不仅是从“患者”中分离出来的,还从“鸟类”中分离出来,从而增加了其人类型受体(NEU5ACα2,6GAL)特异性病毒,这些特异性病毒在那些暴露的人类呼吸道中的附着和感染增加了。我们还鉴定了一种实验性的H5 HA/H1N1病毒。从H5 HA(从H5N1病毒中)完成H5 HA,只有四个氨基酸突变,其余七个基因段来自2009年大流行H1N1病毒。暴露于人类类型受体上的附着增加,并且能够“雪貂模型中的液滴传输”。我们的发现可能有助于促进我们对促成禽有助于影响哺乳动物病毒传播的机制和进化途径的理解。(2)我们还确定了H5N1病毒HA受体N-L-L-L-CHADO的精细化学结构,该sialo糖链的几个靶细胞的H5N1宿主动物的几个靶细胞,例如猪,狗,狗,猫,猫,胚胎的鸡蛋,比15)。感染宿主细胞的病毒受体结合,复制和萌芽。
