摘要

Highlights ► Compared envelopes with expanded coreceptor tropism with those that are strictly CCR5 using for their capacity to utilize CD4 and CCR5. ► Low CD4 dependent envelopes infect primary cells better than those that required optimum CD4 for entry ► No association between low CD4 usage and sensitivity to TAK-779 ► Envelopes with low CD4 usage showed relative resistance to T-20 ► Data throw important insight in disease transmission in late stage in context of subtype C HIV-1 variants.
