An in vivo model for the neurodegenerative effects of beta amyloid and protection by substance P.
Open accessAbstract
Deposition of the beta-amyloid protein in senile plaques is a pathologic hallmark of Alzheimer disease (AD). Focal deposition of beta amyloid in the adult rat cerebral cortex caused profound neurodegenerative changes, including neuronal loss and degenerating neurons and neurites. Chronic induction of the Alz-50 antigen appeared in neurons around focal cortical deposits of beta amyloid. Immunoblot analysis showed that beta amyloid induced Alz-50-immunoreactive proteins in rat cerebral cortex that were very similar to the proteins induced in human cerebral cortex from patients with AD. The neuropeptide substance P prevented beta-amyloid-induced neuronal loss and expression of Alz-50 proteins when coadministered into the cerebral cortex. Systemic administration of substance P also provided protection against the effects of intracerebral beta amyloid. Thus, beta amyloid is a potent neurotoxin in the adult brain in vivo, and its effects can be blocked by substance P.

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.
