Abstract:

目的应用假病毒感染实验快速筛选可用于HIV-1中和抗体测定的功能性膜蛋白基因。方法从HIV感染样品中扩増全长膜蛋白基因gp160,通过系统进化树分析确定其基因亚型,将HIV-1gp160阳性克隆与pSG3△Env质粒共转染293T细胞制备假病毒并对其感染能力进行分析,筛选功能性膜蛋白基因。结果克隆和鉴定了我国HIV-1流行毒株的9个功能性膜蛋白基因,系统进化树分析表明其中包括4个CRF07_BC、2个CRF01_AE和3个B亚型毒株,这些gp160膜蛋白基因所制备的假病毒具有良好的感染性。结论不同亚型HIV-1功能性膜蛋白gp160克隆为选择HIV-1中和抗体测定毒株提供了有价值的实验材料。
