The same was true for CD4+ Jurkat cells, which were electroporated to express PHF13 (figure 5b), such that in BFP-positive cells, which overexpressed PHF13, HIV-1 infection was roughly twofold more efficient when compared with Jurkat cells electroporated with a BFP-only control plasmid (figure 5b). This evidence concerns the gene PHF13 and HIV-1 infection.
