Tracking coreceptor switch of the transmitted/founder HIV-1 identifies co-evolution of HIV-1 antigenicity, coreceptor usage and CD4 subset targeting: the RV217 acute infection cohort study

Abstract excerpt

BACKGROUND: The CCR5 (R5) to CXCR4 (X4) coreceptor switch in natural HIV-1 infection is associated with faster progression to AIDS, but the mechanisms remain unclear. The difficulty in elucidating the evolutionary origin of the earliest X4 viruses limits our understanding of this phenomenon. METHODS: We tracked the evolution of the transmitted/founder (T/F) HIV-1 in RV217 participants identified in acute...
