Abstract

HIV-1-infected individuals can harbor viral isolates that can use CCR5, as well as CXCR4, for viral entry. To genetically engineer HIV-1 resistance in CD4(+) T cells, we assessed whether transient, adenovirus delivered zinc-finger nuclease (ZFN) disruption of genomic cxcr4 or stable lentiviral expression of short hairpin RNAs (shRNAs) targeting CXCR4 mRNAs provides durable resistance to HIV-1 challenge. ZFN-modification of cxcr4 in CD4(+) T cells was found to be superior to cell integrated lentivirus-expressing CXCR4 targeting shRNAs when CD4(+) T cells were challenged with HIV-1s that utilizes CXCR4 for entry. Cxcr4 disruption in CD4(+) T cells was found to be stable, conferred resistance, and provided for continued cell enrichment during HIV-1 infection in tissue culture and, in vivo, in peripheral blood mononuclear cell transplanted NSG mice. Moreover, HIV-1-infected mice with engrafted cxcr4 ZFN-modified CD4(+) T cells demonstrated lower viral levels in contrast to mice engrafted with unmodified CD4(+) T cells. These findings provide evidence that ZFN-mediated disruption of cxcr4 provides a selective advantage to CD4(+) T cells during HIV-1 infection.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
