open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2016
[目的]研究来自不同临床类型H7N9感染者病毒分离株的致病性,探索病毒分子特性与致病差异的关系。[方法]建立人PBMC体外培养及病毒感染模型,人肺组织体外培养及病毒感染模型以及小鼠感染H7N9动物模型,分别从以上3个层次研究两株来自轻症和重症H7N9感染者病毒分离株(即GD-6和GD-7)的感染性及病理损伤状况。[结果]两株病毒均能感染人PBMC、人肺组织体外培养模型和Balb/C小鼠的肺组织中有效复制,并在其中有效复制,且GD-7的增殖能力强于GD-6。病毒主要感染人肺组织的II型肺泡上皮细胞,GD ...
