ABSTRACT Current gene transfer protocols for resting CD4+ T cells include an activation step to enhance transduction efficiency. This step is performed because it is thought that resting cells are resistant to transduction by lentiviral-based gene therapy vectors. However, activating resting cells prior to transduction alters their physiology, with foreseeable and unforeseeable negative consequences. Thus, it would be desirable to transduce resting CD4+ T cells without activation. We recently demonstrated, contrary to the prevailing belief, that wild-type human immunodeficiency virus (HIV) integrates into resting CD4+ T cells. Based on that finding, we investigated whether a commonly used, vesicular stomatitis virus glycoprotein G (VSV-G)-pseudotyped lentiviral gene therapy vector could also integrate into resting CD4+ T cells. To investigate this, we inoculated resting CD4+ T cells with lentiviral particles that were pseudotyped with VSV-G or CXCR4-tropic HIV Env and assayed binding, fusion, reverse transcription, and integration. We found that the VSV-G-pseudotyped lentiviral vector failed to fuse to resting CD4+ T cells while HIV Env-pseudotyped lentiviral vectors fused, reverse transcribed, and integrated in resting cells. Our findings suggest that HIV Env could be used effectively for the delivery of therapeutic genes to resting CD4+ T cells and suggest that fusion may be the critical step restricting transduction of resting CD4+ T cells by lentiviral gene therapy vectors.
