The role of acetylcholinesterase in the pathogenesis of Alzheimer's disease
Abstract
Treatment of Alzheimer's disease has been dominated by the use of acetylcholinesterase (AChE) inhibitors. These drugs compensate for the death of cholinergic neurons and offer symptomatic relief by inhibiting acetylcholine (ACh) turnover and restoring synaptic levels of this neurotransmitter. Recently, however, AChE itself has been implicated in the pathogenesis of Alzheimer's disease. In particular, it appears that AChE may directly interact with amyloid-beta in a manner that increases the deposition of this peptide into insoluble plaques. This new role suggests that properly designed AChE inhibitors might be able to act as disease-modifying agents rather than as mere palliatives. Additionally, numerous studies have suggested that cholinergic modulation and other functional consequences of AChE inhibition may affect amyloid precursor protein processing and protect neurons against a variety of insults. It therefore seems likely that new AChE inhibitors, which capitalize on all these strengths would be excellent candidates for future Alzheimer's disease therapy.

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.
