Apolipoprotein E: a pathological chaperone protein in patients with cerebral and systemic amyloid

Open access
Wisniewski, Thomas, Frangione, Blas·1992·Neuroscience Letters

Abstract

Many biochemically diverse proteins can give rise to amyloid fibrils; however, they are all accompanied by P component and glucosaminoglycans. With antibodies specific to apolipoprotein E (apo E) we used immunohistochemical techniques to test for the presence of this protein in both cerebral and systemic amyloid. We found apo E immunoreactivity in all tested types of cerebral and systemic amyloid. In amyloid deposits apo E P, component and glucosaminoglycans may be acting as 'pathological molecular chaperones'. The latter we define as a group of unrelated proteins that induce beta-pleated conformation in amyloidogenic polypeptides.

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.
