Abstract

PURPOSE OF REVIEW: Recent clinical research suggests that an HIV-infected patient with lymphoma who was transplanted with bone marrow homozygous for a disrupted mutant CCR5 allele has no remaining HIV replication and is effectively cured of HIV. Here, we discuss the approaches of disrupting host and viral genes involved in HIV replication and pathogenesis with the aim of curing patients with HIV. RECENT FINDINGS: Data from the 'Berlin patient' suggest that targeted gene disruption can lead to an HIV cure. This review discusses the recent advances in the field of gene disruption toward the development of an anti-HIV therapy. We will introduce the strategies to disrupt host and viral genes using precise disruptions, imprecise disruptions, or site-specific recombination. Furthermore, the production of engineered rare-cutting endonucleases (zinc finger nucleases, TAL effector nucleases, and homing endonucleases) and recombinases that can recognize specific DNA target sequences and facilitate gene disruption will be discussed. SUMMARY: The discovery of a gene disruption approach that would cure or efficiently confine HIV infection could have broad implications for the treatment of millions of people infected with HIV. An efficient 'one-shot' curative therapy not only would give infected patients hope of a drug-free or treatment-free future, but also could reduce the huge financial burden faced by many countries because of widespread administration of highly active antiretroviral therapy.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Nuclease-based approaches have been used to disrupt HIV-1 entry coreceptors CCR5 or CXCR4 and proviral DNA-encoding viral proteins.

    “These approaches have been used to disrupt HIV-1 entry coreceptors C-C chemokine receptor 5 (CCR5) or C-C-C chemokine receptor 4 (CXCR4) and proviral DNA-encoding viral proteins”
  • Engineered nucleases including ZFN, TALEN, and CRISPR Cas9 can disrupt target genes and have raised prospects of selectively deleting HIV-1 proviral DNA integrated into the host genome.

    “Advances in the engineered nucleases including zinc finger nuclease (ZFN), transcription activator-like effector nuclease (TALEN), and clustered regularly interspaced short palindromic repeats (CRISPR) associated 9 (Cas9) that can disrupt target genes have raised prospects of selectively deleting HIV-1 proviral DNA integrated into the host genome”

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.
