Engineering Liver-detargeted AAV9 Vectors for Cardiac and Musculoskeletal Gene Transfer
Open accessAbstract
We report the generation of a new class of adeno-associated virus serotype 9 (AAV9)-derived vectors displaying selective loss of liver tropism and demonstrating potential for cardiac and musculoskeletal gene transfer applications. Random mutagenesis of residues within a surface-exposed region of the major AAV9 capsid protein yielded a capsid library with mutations clustered at the icosahedral threefold symmetry axis. Using a combination of sequence analysis, structural models, and in vivo screening, we identified several functionally diverse AAV9 variants. The latter were classified into three functional subgroups, with respect to parental AAV9 displaying: (i) decreased transduction efficiency across multiple tissues; (ii) a selective decrease in liver transduction, or (iii) a similar transduction profile. Notably, variants 9.45 and 9.61 (subgroup II) displayed 10- to 25-fold lower gene transfer efficiency in liver, while transducing cardiac and skeletal muscle as efficiently as AAV9. These results were further corroborated by quantitation of vector genome copies and histological analysis of reporter (tdTomato) gene expression. The study highlights the feasibility of generating AAV vectors with selectively ablated tissue tropism, which when combined with other targeting strategies could allow sharply segregated gene expression. Liver-detargeted AAV9 variants described herein are excellent candidates for preclinical evaluation in animal models of cardiac and musculoskeletal disease.

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.
