Cholesterol depletion inhibits the generation of β-amyloid in hippocampal neurons
Open accessAbstract
The amyloid precursor protein (APP) plays a crucial role in the pathogenesis of Alzheimer’s disease. During intracellular transport APP undergoes a series of proteolytic cleavages that lead to the release either of an amyloidogenic fragment called β-amyloid (Aβ) or of a nonamyloidogenic secreted form consisting of the ectodomain of APP (APP sec ). It is Aβ that accumulates in the brain lesions that are thought to cause the disease. By reducing the cellular cholesterol level of living hippocampal neurons by 70% with lovastatin and methyl-β-cyclodextrin, we show that the formation of Aβ is completely inhibited while the generation of APP sec is unperturbed. This inhibition of Aβ formation is accompanied by increased solubility in the detergent Triton X-100 and is fully reversible by the readdition of cholesterol to previously depleted cells. Our results show that cholesterol is required for Aβ formation to occur and imply a link between cholesterol, Aβ, and Alzheimer’s disease.

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.
