Adeno-associated virus vector as a platform for gene therapy delivery

Open access
Wang, Dan, Tai, Phillip W. L., Gao, Guangping·2019·Nature Reviews Drug Discovery

Abstract

Adeno-associated virus (AAV) vectors are the leading platform for gene delivery for the treatment of a variety of human diseases. Recent advances in developing clinically desirable AAV capsids, optimizing genome designs and harnessing revolutionary biotechnologies have contributed substantially to the growth of the gene therapy field. Preclinical and clinical successes in AAV-mediated gene replacement, gene silencing and gene editing have helped AAV gain popularity as the ideal therapeutic vector, with two AAV-based therapeutics gaining regulatory approval in Europe or the United States. Continued study of AAV biology and increased understanding of the associated therapeutic challenges and limitations will build the foundation for future clinical success.

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

  • A primary immune response to the treatment may be triggered by the presence of pre-existing neutralizing antibodies (NABs) against rAAV capsids, due to previous naturally-occurring exposure to AAV.

    “A primary immune response to the treatment may be triggered by the presence of pre-existing neutralizing antibodies (NABs) against rAAV capsids, due to previous naturally-occurring exposure to AAV [1, 3].”

    From Characterization of anti-AAV2 neutralizing antibody levels in sheep prior to and following intravitreal AAV2.7m8 injection (2024) · cites this paper as [3]

    In “Immunological barriers to rAAV gene delivery,” the paper says neutralizing antibodies from natural AAV infection can be present before treatment and can block rAAV delivery. It separately says that administration of the vector capsid triggers a humoral immune response; it does not say pre-existing antibodies trigger a primary immune response to treatment. (LLM, conf=0.85)

  • Host immune responses against AAV vectors and delivered transgene impact effective and stable transgene expression.

    “However, host immune responses against AAV vectors and delivered transgene impact effective and stable transgene expression [10, 11].”
  • One of the first approaches to show gene transfer in mouse retina used rAAV vectors to deliver a reporter gene by subretinal injection into an adult mouse retina.

    “One of the first approaches to show gene transfer in mouse retina used rAAV vectors to deliver a reporter gene by subretinal injection into an adult mouse retina [62].”

    From The Ocular Gene Delivery Landscape (2021) · cites this paper as [62]

  • The therapeutic payload must be under 5 kb and must include regulatory elements such as the promoter and polyadenylation signal.

    “The therapeutic payload must be under 5 kb and must include the regulatory elements, such as the promoter and polyadenylation signal [61,62].”

    From The Ocular Gene Delivery Landscape (2021) · cites this paper as [62]

  • The proteasome degradation pathway results in unsuccessful transduction, and capsid-derived peptides are presented to CTL by MHC class I molecules, provoking elimination of transduced cells and loss of transgene expression.

    “The latter pathway results in unsuccessful transduction, and capsid-derived peptides are presented to CTL by MHC class I molecules, provoking elimination of transduced cells and loss of transgene expression (85).”

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.
