Critical genetic adaptations needed for SIV chimpanzee to evolve into HIV-1 are not well understood. Using humanized mice, we mimicked the evolution of SIVcpzLB715 into HIV-1 Group M over the course of four generations. Higher initial viral load, increased CD4 T-cell decline, and nonsynonymous substitutions arose suggesting viral evolution.
对于 SIV 黑猩猩进化成 HIV-1 所需的关键遗传适应性还不是很了解。我们使用人源化小鼠模拟了 SIVcpzLB715 在四代内进化成 HIV-1 M 组的过程。更高的初始病毒载量、CD4 T 细胞下降增加和非同义替换的出现表明了病毒的进化。
