Abstract
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.
