Abstract

Studies have shown that clusterin (also called apolipoprotein J) can influence the structure and toxicity of amyloid-beta (Abeta) in vitro. To determine whether endogenous clusterin plays a role in influencing Abeta deposition, structure, and toxicity in vivo, we bred PDAPP mice, a transgenic mouse model of Alzheimer's disease, to clusterin(-/-) mice. By 12 months of age, PDAPP, clusterin(-/-) mice had similar levels of brain Abeta deposition as did PDAPP, clusterin(+/+) mice. Although Abeta deposition was similar, PDAPP, clusterin(-/-) mice had significantly fewer fibrillar Abeta (amyloid) deposits than PDAPP mice expressing clusterin. In the absence of clusterin, neuritic dystrophy associated with the deposited amyloid was markedly reduced, resulting in a dissociation between fibrillar amyloid formation and neuritic dystrophy. These findings demonstrate that clusterin markedly influences Abeta structure and neuritic toxicity in vivo and is likely to play an important role in Alzheimer's disease pathogenesis.

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.
