Abstract

As adeno-associated virus (AAV)-based gene therapies are being increasingly approved for use in humans, it is important that we understand vector-host interactions in detail. With the advances in genome-wide genetic screening tools, a clear picture of AAV-host interactions is beginning to emerge. Understanding these interactions can provide insights into the viral life cycle. Accordingly, novel strategies to circumvent the current limitations of AAV-based vectors may be explored. Here, we summarize our current understanding of the various stages in the journey of the vector from the cell surface to the nucleus and contextualize the roles of recently identified host factors.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • After endosomal escape, rAAV particles either enter the nucleus for transgene expression, or become ubiquitylated then degraded by proteasome.

    “After endosomal escape, rAAV particles either enter the nucleus for transgene expression, or become ubiquitylated then degraded by proteasome (84).”
  • Endosomal acidification is essential for rAAV escape, and hydroxychloroquine increases endosomal and lysosomal pH, so the effect may not be replicated or consistent with systemic application.

    “However, endosomal acidification is essential for rAAV escape (84), and hydroxychloroquine increases endosomal and lysosomal pH (60), this effect may not be replicated or consistent with systemic application.”

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.
