Abstract

APPsw transgenic mice bearing the "Swedish" amyloid precursor protein (APP) mutation and JNPL3 transgenic mice bearing the P301L (Tau) mutation were compared to control non-transgenic (NT) mice in an extensive behavioral test battery administered between 5 and 8.5 months of age. APP mice were impaired in a variety of cognitive-based tasks prior to overt Abeta plaque development, making involvement of mutant APP overexpression and/or oligomeric Abeta assemblies most likely. Although Tau mice, as a group, were not impaired in any single behavioral measure, a collective assessment of behavioral measures through discriminant function analysis showed that Tau mice were impaired in overall behavioral (cognitive) performance. Moreover, correlation analyses involving Tau mice alone revealed linkage between poorer cognitive performance in all three water maze tasks and the number of neurofibrillary tangle (NFT)-containing neurons in neocortex and hippocampus. These findings indicate that: (1) APP mice show early and extensive cognitive impairment before evident Abeta deposition, and (2) the process or product of NFT formation in Tau mice is sufficient to deleteriously impact cognitive performance.

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.
