Abstract

Amyloid beta peptides and microtubule-associated protein Tau are misfolded and form aggregates in brains of Alzheimer's disease patients. To examine their specific roles in the pathogenesis of Alzheimer's disease and their relevance in neurodegenerative processes, we have created TauPS2APP triple transgenic mice that express human mutated Amyloid Precursor Protein, presenilin 2 and Tau. We present a cross-sectional analysis of these mice at 4, 8, 12 and 16 months of age. By comparing with single transgenic Tau mice, we demonstrate that accumulation of Abeta in TauPS2APP triple transgenic mice impacts on Tau pathology by increasing the phosphorylation of Tau at serine 422, as determined by a novel immunodetection method that is able to reliably measure phospho-Tau species in transgenic mouse brains. The TauPS2APP triple transgenic mouse model will be very useful for studying the effect of new therapeutic paradigms on amyloid deposition and downstream neurofibrillary tangle development.

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

  • Findings in models harboring transgenic Aβ peptides in the absence of APP overexpression strikingly contrast the obvious exacerbation of tau pathology observed in tau transgenic mice when crossed with mouse models of AD overexpressing mutant APP.

    “These findings in models harboring transgenic Aβ peptides in the absence of APP overexpression strikingly contrast the obvious exacerbation of tau pathology observed in tau transgenic mice when crossed with mouse models of AD overexpressing mutant APP [7,8,9,10,11,12,13,36].”
  • A limited number of studies have reported animal models that display both plaques and tangles.

    “A limited number of studies have reported the development of animal models that display both plaques and tangles [10, 51, 91, 109, 121].”

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.
