Design: We analyzed the effects of one GPCR coexpressed with CCR5, EBI2, on HIV-1 replicative cycle. Methods: We identified GPCRs expressed in primary CD4+CCR5+ T cells by multi-RT-qPCR. Cell lines expressing EBI2 were established by transduction with HIV vectors. The amount of HIV reverse transcripts was similar in cells expressing or not EBI2. Conclusions: EBI2 expression in CD4+CCR5+ cells boosts HIV-1 R5 productive infection.
