Abstract

Adeno-associated virus (AAV) vectors have emerged as a gene-delivery platform with demonstrated safety and efficacy in a handful of clinical trials for monogenic disorders. However, limitations of the current generation vectors often prevent broader application of AAV gene therapy. Efforts to engineer AAV vectors have been hampered by a limited understanding of the structure-function relationship of the complex multimeric icosahedral architecture of the particle. To develop additional reagents pertinent to further our insight into AAVs, we inferred evolutionary intermediates of the viral capsid using ancestral sequence reconstruction. In-silico-derived sequences were synthesized de novo and characterized for biological properties relevant to clinical applications. This effort led to the generation of nine functional putative ancestral AAVs and the identification of Anc80, the predicted ancestor of the widely studied AAV serotypes 1, 2, 8, and 9, as a highly potent in vivo gene therapy vector for targeting liver, muscle, and retina.

  • In silico design approach to reconstruct and discover new capsid was first reported in 2015.

    “With technological advancements of computational modeling and machine learning, an in silico design approach to reconstruct and discover new capsid was first reported in 2015 [69, 70].”

    From Designing and optimizing AAV-mediated gene therapy for neurodegenerative diseases: from bench to bedside (2024) · cites this paper as [69]

    The Discussion (page unavailable) says the authors inferred ancestral AAV capsid sequences through in silico modeling and identified a new AAV-like particle, Anc80L65. It does not establish that this approach was first reported in 2015; it describes an earlier viral-ancestor reconstruction as a methodological precedent. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • AAV8 and Anc80L65 both transduce retinal cells with high efficiencies.

    “Effect of serotype on vector reconstitution was studied by comparing AAV8 and Anc80L65, both of which transduce retinal cells with high efficiencies (Zinn et al., 2015).”

    From Evaluating Efficiencies of Dual AAV Approaches for Retinal Targeting (2017) · cites this paper as Zinn et al., 2015

  • The Anc80 serotype, produced by mining the parvovirus ancestral genome, has promise as a safer vector for gene therapy.

    “This strategy produced the Anc80 serotype with the promise of a safer vector for GT [116].”

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.
