Abstract

Vectors based on adeno-associated virus (AAV) serotype 9 are candidates for in vivo gene delivery to many organs, but the receptor(s) mediating these tropisms have yet to be defined. We evaluated AAV9 uptake by glycans with terminal sialic acids (SAs), a common mode of cellular entry for viruses. We found, however, that AAV9 binding increased when terminal SA was enzymatically removed, suggesting that galactose, which is the most commonly observed penultimate monosaccharide to SA, may mediate AAV9 transduction. This was confirmed in mutant CHO Pro-5 cells deficient in the enzymes involved in glycoprotein biogenesis, as well as lectin interference studies. Binding of AAV9 to glycans with terminal galactose was demonstrated via glycan binding assays. Co-instillation of AAV9 vector with neuraminidase into mouse lung resulted in exposure of terminal galactose on the apical surface of conducting airway epithelial cells, as shown by lectin binding and increased transduction of these cells, demonstrating the possible utility of this vector in lung-directed gene transfer. Increasing the abundance of the receptor on target cells and improving vector efficacy may improve delivery of AAV vectors to their therapeutic targets.

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.
