Clearing the brain's amyloid cobwebs
Open accessAbstract
Elevated cerebral levels of amyloid beta-protein occur universally in Alzheimer's disease, yet only a few patients show evidence of increased Abeta production. Therefore, defects in proteases that degrade Abeta could underlie some or many cases of familial and sporadic AD. This previously neglected topic has begun receiving serious attention. Understanding how proteolysis regulates Abeta levels in the cerebral cortex has implications for both the pathogenesis and the treatment of this protean disorder.

Defects in the clearance of brain Aβ by cellular uptake or transport across the blood-brain barrier might underlie many cases of sporadic AD.
“Defects in the clearance of brain Aβ by cellular uptake or transport across the blood-brain barrier might underlie many cases of sporadic AD (Selkoe, 2001; Zlokovic, 2008).”
From The role of apolipoprotein E in Alzheimer's disease (2009) · cites this paper as Selkoe, 2001
The passage labeled Abstract (page unavailable) says faulty Aβ clearance may cause many, perhaps most, AD cases, supporting the claim’s general possibility. The paper discusses microglial removal and transport of Aβ-antibody complexes out of the brain in the context of immunization, but it does not link defects in cellular uptake or blood-brain-barrier transport specifically to many sporadic AD cases.

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.
