Abstract

Delivery of genes to the brain and spinal cord across the blood-brain barrier (BBB) has not yet been achieved. Here we show that adeno-associated virus (AAV) 9 injected intravenously bypasses the BBB and efficiently targets cells of the central nervous system (CNS). Injection of AAV9-GFP into neonatal mice through the facial vein results in extensive transduction of dorsal root ganglia and motor neurons throughout the spinal cord and widespread transduction of neurons throughout the brain, including the neocortex, hippocampus and cerebellum. In adult mice, tail vein injection of AAV9-GFP leads to robust transduction of astrocytes throughout the entire CNS, with limited neuronal transduction. This approach may enable the development of gene therapies for a range of neurodegenerative diseases, such as spinal muscular atrophy, through targeting of motor neurons, and amyotrophic lateral sclerosis, through targeting of astrocytes. It may also be useful for rapid postnatal genetic manipulations in basic neuroscience studies.

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

  • AAV9 can cross the blood-brain barrier and transduce both neurons and astrocytes after intravenous administration.

    “AAV9 can cross the blood–brain barrier and transduce both neurons and astrocytes after intravenous administration.7,10–11”
  • AAV8 and AAV5 transduce a significantly greater area of the CNS in comparison with AAV2.

    “AAV8 and AAV5 transduce a significantly greater area of the CNS in comparison with AAV2”

    From Characterization of a novel adeno-associated viral vector with preferential oligodendrocyte tropism (2016) · cites this paper as [11]

    The Introduction (page unavailable) says AAV8 showed poor CNS penetration after vascular delivery, but it does not compare AAV8 with AAV2. Searches for AAV5, AAV2, and CNS transduction area found no passage comparing the three serotypes or reporting a significant difference. (LLM, conf=0.77)

  • In SMA murine models, systemically delivered self-complementary AAV9 crossed the blood brain barrier and achieved high levels of neuronal transduction.

    “It was confirmed in SMA murine models that systemically delivered self-complementary AAV9 (scAAV9) crossed the blood brain barrier and achieved high levels of neuronal transduction.9,10”
  • The discovery of newer AAV capsids, such as AAV9, has permitted a much wider degree of gene transfer than multiple stereotaxic injections.

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.
