Chronic nicotine administration exacerbates tau pathology in a transgenic model of Alzheimer's disease
Open accessAbstract
The association between nicotinic acetylcholine receptor (nAChR) dysfunction and cognitive decline in Alzheimer's disease (AD) has been widely exploited for its therapeutic potential. The effects of chronic nicotine exposure on Aβ accumulation have been studied in both humans and animal models, but its therapeutic efficacy for AD neuropathology is still unresolved. To date, no in vivo studies have addressed the consequences of activating nAChRs on tau pathology. To determine the effects of chronic nicotine administration on Aβ and tau pathology, we chronically administrated nicotine to a transgenic model of AD (3xTg-AD) in their drinking water. Here, we show that chronic nicotine intake causes an up-regulation of nicotinic receptors, which correlated with a marked increase in the aggregation and phosphorylation state of tau. These data show that nicotine exacerbates tau pathology in vivo . The increase in tau phosphorylation appears to be due to the activation of p38-mitogen-activated protein kinase, which is known to phosphorylate tau in vivo and in vitro . We also show that the 3xTg-AD mice have an age-dependent reduction of α7nAChRs compared with age-matched nontransgenic mice in specific brain regions. The reduction of α7nAChRs is first apparent at 6 months of age and is restricted to brain regions that show intraneuronal Aβ 42 accumulation. Finally, this study highlights the importance of testing compounds designed to ameliorate AD pathology in a model with both neuropathological lesions because of the differential effects it can have on either Aβ or tau.

In the citing paper
“Elevated p38 activity is found in brains from patients with tauopathies (145–147) and in transgenic AD mice models expressing human tau (148–150) or mutant APP (151), both of which correlate with tau aggregation.”

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.
