Abstract

Alzheimer's disease (AD) is an important social and economic issue for our societies. The development of therapeutics against this severe dementia requires assessing the effects of new drugs in animal models thanks to dedicated biomarkers. According to the amyloid cascade hypothesis, β-amyloid deposits are at the origin of most of the lesions associated with AD. These extracellular deposits are therefore one of the main targets in therapeutical strategies. Aβ peptides can be revealed histologically with specific dyes or antibodies, or by magnetic resonance microscopy (μMRI) that uses their association with iron as a source of signal. The microscopic size of the lesions necessitates the development of specific imaging protocols. Most protocols use T (2)-weighted sequences that reveal the aggregates as hypointense spots. This chapter describes histological methods that reveal amyloid plaques with specific stains and MR-imaging protocols for in vivo and ex vivo MR imaging of AD mice.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Senile plaques have been observed with MRI in postmortem human tissues and Alzheimer's disease transgenic mice.

    “Although senile plaques have been observed with MRI in both postmortem human tissues and AD transgenic mice, 7”

    From Amyloid Plaque Imaging with a Targeted MRI Contrast Agent in a Transgenic Mouse Model of Alzheimer’s Disease (2022) · cites this paper as [7]

    The Introduction says the chapter describes MRI methods for detecting amyloid plaques in vivo and ex vivo in transgenic AD mice. It does not report MRI observation of plaques in postmortem human tissue; its discussion of human plaque imaging instead concerns PET. That human-tissue part of the claim is unsupported by our copy.

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.
