Neuronal IGF‐1 resistance reduces Aβ accumulation and protects against premature death in a model of Alzheimer's disease
Abstract
Alzheimer's disease (AD) is characterized by progressive neurodegeneration leading to loss of cognitive abilities and ultimately to death. Postmortem investigations revealed decreased expression of cerebral insulin‐like growth factor (IGF)‐1 receptor (IGF‐1R) and insulin receptor substrate (IRS) proteins in patients with AD. To elucidate the role of insulin/IGF‐1 signaling in AD, we crossed mice expressing the Swedish mutation of amyloid precursor protein (APP SW , Tg2576 mice) as a model for AD with mice deficient for either IRS‐2, neuronal IGF‐1R (nIGF‐1R −/− ), or neuronal insulin receptor (nIR −/− ), and analyzed survival, glucose, and APP metabolism. In the present study, we show that IRS‐2 deficiency in Tg2576 mice completely reverses premature mortality in Tg2576 females and delays β‐amyloid (Aβ) accumulation. Analysis of APP metabolism suggested that delayed Aβ accumulation resulted from decreased APP processing. To delineate the upstream signal responsible for IRS‐2‐mediated disease protection, we analyzed mice with nIGF‐1R or nIR deficiency predominantly in the hippocampus. Interestingly, both male and female nIGF‐1R −/− Tg2576 mice were protected from premature death in the presence of decreased Aβ accumulation specifically in the hippocampus formation. However, neuronal IR deletion had no influence on lethality of Tg2576 mice. Thus, impaired IGF‐1/IRS‐2 signaling prevents premature death and delays amyloid accumulation in a model of AD.—Freude, S., Hettich, M.

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.
