Forty-eight hours after activation, CD4+ T cells from the original high permissive donor (donor #42) were infected with HIV-GFP and 24h later, a panel of 332 PE-conjugated antibodies (LEGENDScreen Human Cell Screening, BioLegend) was used to investigate by FACS the co-occurrence of cell surface proteins and successful infection (Fig 2A). This evidence concerns the gene CD4 and infection.
