Apolipoprotein E in sporadic Alzheimer's disease: Allelic variation and receptor interactions

William Rebeck, G., Reiter, Joell S., Strickland, Dudley K., Hyman, Bradley T.·1993·Neuron

Abstract

An increased prevalence of apolipoprotein E (ApoE) epsilon 4 allele exists in late onset familial Alzheimer's disease. We found, in sporadic Alzheimer's disease, that 62% of patients possessed an ApoE-epsilon 4 allele, compared with 20% of controls. ApoE-epsilon 4/4 patients had more senile plaques (SPs) than epsilon 3/3 patients. ApoE immunoreactivity of SPs was equivalent in both groups. Two receptors bind ApoE complexes, the low density lipoprotein (LDL) receptor and the LDL receptor-related protein (LRP). In normal brain, anti-LRP antibodies strongly stained neurons and lightly stained astrocytes; anti-LDL receptor antibodies stained only the neuropil and astrocytes. In Alzheimer's disease, SPs and reactive astrocytes were also strongly LRP immunoreactive. Colocalization of ApoE and LRP to SPs implies that these molecules may be involved in metabolism of components of SPs.

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.
