Abstract

Adeno-associated viral (AAV) vectors have demonstrated considerable promise for gene therapy of inherited diseases. However, with a packaging size of <5 kb, applications have been limited to relatively small disease genes. Based on the finding that AAV genomes undergo intermolecular circular concatamerization after transduction in muscle, we have developed a paradigm to increase the size of delivered transgenes with this vector through trans-splicing between two independent vectors coadministered to the same tissue. When two vectors encoding either the 5′ or 3′ portions of the erythropoietin genomic locus were used, functional erythropoietin protein was expressed in muscle subsequent to the formation of intermolecular circular concatamers in a head-to-tail orientation through trans-splicing between these two independent vector genomes. These findings will allow for the application of AAV technologies to a wider variety of diseases for which therapeutic transgenes exceed the packaging limitation of present AAV vectors.

  • Split vector systems exploiting head-to-tail concatamerization have been developed to circumvent the small packaging capacity of AAV genomes.

    “Recently, split vector systems, exploiting head-to-tail concatamerization formation, have been developed to circumvent the small packaging capacity of AAV genomes (13-16, 41, 52).”
  • The trans-splicing method to expand the size of ORFs that can be successfully expressed using AAV vectors was originally developed in the laboratory of John Engelhardt and has since been utilized in several studies with varying success.

    “The trans-splicing method to expand the size of ORFs that can be successfully expressed using AAV vectors was originally developed in the laboratory of John Engelhardt 52,53 and has since been utilized in several studies with varying success (e.g., refs. 53-57 ).”

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.
