Long‐term evolutionary adaptation of SIVcpz toward HIV‐1 using a humanized mouse model.

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. [ABSTRACT FROM AUTHOR]
