Abstract

Immunotherapy against beta-amyloid peptide (Abeta) is a leading therapeutic direction for Alzheimer disease (AD). Experimental studies in transgenic mouse models of AD have demonstrated that Abeta immunization reduces Abeta plaque pathology and improves cognitive function. However, the biological mechanisms by which Abeta antibodies reduce amyloid accumulation in the brain remain unclear. We provide evidence that treatment of AD mutant neuroblastoma cells or primary neurons with Abeta antibodies decreases levels of intracellular Abeta. Antibody-mediated reduction in cellular Abeta appears to require that the antibody binds to the extracellular Abeta domain of the amyloid precursor protein (APP) and be internalized. In addition, treatment with Abeta antibodies protects against synaptic alterations that occur in APP mutant neurons.

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

  • In neuronal cultures derived from APP SW mice, application of anti-Aβ monoclonal antibodies resulted in reduced intraneuronal Aβ accumulation after the antibodies bound to the extracellular APP domain and became internalized.

    “Limited examples include application of anti-Ab mAbs into neuronal culture derived from APP SW mice, whereby mAbs after binding to extracellular APP domain became internalized, resulting in reduced intraneuronal Ab accumulation.58”
  • Aβ antibodies can reduce the intraneuronal pool of Aβ in vivo and in vitro; in vitro required Aβ antibody internalization.

    “Remarkably, it was demonstrated that Aβ antibodies can reduce the intraneuronal pool of Aβ in vivo [138] and in vitro [189], which for the latter was shown to required Aβ antibody internalization.”

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.
