Multiple APOBEC3 proteins are expressed in HIV-1 target cells, but their individual contributions to viral suppression when expressed at endogenous levels remain largely unknown. We used an HIV NL4-3 mutant that selectively counteracts APOBEC3G (A3G) but not APOBEC3F (A3F) to dissect the relative contribution of A3F to the inhibition of HIV-1 replication in primary human lymphocytes (peripheral blood mononuclear cells [PBMCs]). This HIV Vif mutant replicated similarly to wild-type virus in PBMCs, suggesting that the effect of A3F on HIV restriction in these cells is limited. The different A3F variants found in PMBC donors displayed either comparable activity or less activity than wild-type A3F. Lastly, the endogenous A3F mRNA and protein expression levels in PBMCs were considerably lower than those of A3G. Our results suggest that A3F neutralization is dispensable for HIV-1 replication in primary human T-lymphocytes.
