Abstract

Injection of adeno-associated virus (AAV) into the cerebrospinal fluid (CSF) offers a means to achieve widespread transgene delivery to the central nervous system, where the doses can be readily translated from small to large animals. In contrast to studies with other serotypes (AAV2, AAV4 and AAV5) in rodents, we report that a naturally occurring capsid (AAV9) and rationally engineered capsid (AAV2.5) are able to achieve broad transduction throughout the brain and spinal cord parenchyma following a single injection into the CSF (via cisterna magna or lumbar cistern) in non-human primates (NHP). Using either vector at a dose of ∼2 × 10(12) vector genome (vg) per 3-6 kg animal, approximately 2% of the entire brain and spinal cord was transduced, covering all regions of the central nervous system (CNS). AAV9 in particular displayed efficient transduction of spinal cord motor neurons. The peripheral organ biodistribution was highly reduced compared with intravascular delivery, and the presence of circulating anti-AAV-neutralizing antibodies up to a 1:128 titer had no inhibitory effect on CNS gene transfer. Intra-CSF delivery effectively translates from rodents to NHPs, which provides encouragement for the use of this approach in humans to treat motor neuron and lysosomal storage diseases.

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

  • The circulation of CSF delivers viral vectors to broader CNS regions when compared to IP injection.

    “The circulation of CSF delivers viral vectors to broader CNS regions when compared to IP injection [86].”

    From Designing and optimizing AAV-mediated gene therapy for neurodegenerative diseases: from bench to bedside (2024) · cites this paper as [86]

    The Introduction (page unavailable) says that injection into CSF allows diffuse delivery to large areas of the brain and spinal cord. The Discussion (page unavailable) reports widespread CNS transduction after lumbar-cistern injection. Neither passage establishes that this delivery reaches broader CNS regions than IP injection; the paper’s described comparisons concern other injection routes. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • In animal models, widespread CNS coverage can be obtained by delivering the vector into the CSF.

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.
