Abstract

Noninvasive systemic gene delivery to the central nervous system (CNS) has largely been impeded by the blood-brain barrier (BBB). Recent studies documented widespread CNS gene transfer after intravascular delivery of recombinant adeno-associated virus 9 (rAAV9). To investigate alternative and possibly more potent rAAV vectors for systemic gene delivery across the BBB, we systematically evaluated the CNS gene transfer properties of nine different rAAVEGFP vectors after intravascular infusion in neonatal mice. Several rAAVs efficiently transduce neurons, motor neurons, astrocytes, and Purkinje cells; among them, rAAVrh.10 is at least as efficient as rAAV9 in many of the regions examined. Importantly, intravenously delivered rAAVs did not cause abnormal microgliosis in the CNS. The rAAVs that achieve stable widespread gene transfer in the CNS are exceptionally useful platforms for the development of therapeutic approaches for neurological disorders affecting large regions of the CNS as well as convenient biological tools for neuroscience research.

  • AAVrh.8 better transduces neurons, astrocytes, and oligodendrocytes and has low peripheral tropism compared to AAV9 and AAVrh.10.

    “AAVrh.8 was shown to better transduce neurons, astrocytes, and oligodendrocytes, while with low peripheral tropism compared to AAV9 and AAVrh.10 [126, 127].”

    From Designing and optimizing AAV-mediated gene therapy for neurodegenerative diseases: from bench to bedside (2024) · cites this paper as [127]

    The Discussion (page unavailable) identifies rAAVrh.10, rAAVrh.39, rAAVrh.43, and rAAV9 as effective CNS vectors, but does not assess AAVrh.8. Searches for AAVrh.8, oligodendrocytes, and peripheral tropism found no passage supporting the claimed comparison. (LLM, conf=0.76)

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.
