Abstract

Significance: Patients homozygous for the C-C chemokine receptor type 5 (CCR5) gene with 32-bp deletions (Δ32) are resistant to HIV infection. Using the piggyBac technology plus transcription activator-like effector nucleases or clustered regularly interspaced short palindromic repeats-Cas9, the authors report, to our knowledge, for the first time in induced pluripotent stem cells (iPSCs) the efficient and seamless derivation of a homozygous CCR5Δ32 mutation, exactly mimicking the natural mutation. Monocytes and macrophages differentiated from these mutated iPSCs in vitro are resistant to HIV infection. This approach can be applied in the future toward the functional cure of HIV infection. The findings are also of great interest to researchers in many fields who wish to correct or introduce mutations in specific genes.

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.
