Abstract

Recombinant adeno-associated viral (rAAV) vectors are potentially powerful tools for gene therapy of CNS diseases, but their penetration into brain parenchyma is severely limited by the blood-brain barrier (BBB) and current delivery relies on invasive stereotactic injection. Here we evaluate the local, targeted delivery of rAAV vectors into the brains of mice by noninvasive, reversible, microbubble-facilitated focused ultrasound (FUS), resulting in BBB opening that can be monitored and controlled by magnetic resonance imaging (MRI). Using this method, we found that IV-administered AAV2-GFP (green fluorescence protein) with a low viral vector titer (1×10(9) vg/g) can successfully penetrate the BBB-opened brain regions to express GFP. We show that MRI monitoring of BBB-opening could serve as an indicator of the scale and distribution of AAV transduction. Transduction peaked at 3 weeks and neurons and astrocytes were affected. This novel, noninvasive delivery approach could significantly broaden the application of AAV-viral-vector-based genes for treatment of CNS diseases.

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

  • AAV1, AAV2, or chimeric AAV1/2 vectors, which showed low BBB-crossing per se, successfully penetrated into directed brain regions after FUS-MB treatment.

    “It was reported that IV infusion of AAV1, AAV2 or chimeric AAV1/2 vector, which showed low BBB-crossing per se, successfully penetrated into directed brain regions after FUS-MB treatment [140–142].”

    From Designing and optimizing AAV-mediated gene therapy for neurodegenerative diseases: from bench to bedside (2024) · cites this paper as [140]

    The Abstract and Discussion report that intravenously administered AAV2 entered targeted, FUS-opened brain regions in mice, while the Introduction and Results describe poor delivery across an intact BBB. The paper does not report FUS-assisted brain delivery of AAV1 or chimeric AAV1/2 vectors, so it supports only the AAV2 portion of the sentence. (LLM, conf=0.86)

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.
