Abstract

Accumulation of amyloid-beta (Abeta) is one of the earliest molecular events in Alzheimer disease (AD), whereas tau pathology is thought to be a later downstream event. It is now well established that Abeta exists as monomers, oligomers, and fibrils. To study the temporal profile of Abeta oligomer formation in vivo and to determine their interaction with tau pathology, we used the 3xTg-AD mice, which develop a progressive accumulation of plaques and tangles and cognitive impairments. We show that SDS-resistant Abeta oligomers accumulate in an age-dependent fashion, and we present evidence to show that oligomerization of Abeta appears to first occur intraneuronally. Finally, we show that a single intrahippocampal injection of a specific oligomeric antibody is sufficient to clear Abeta pathology, and more importantly, tau pathology. Therefore, Abeta oligomers may play a role in the induction of tau pathology, making the interference of Abeta oligomerization a valid therapeutic target.

  • In 3xTg-AD mice, both Aβ and tau exhibit age- and region-dependent formation, with Aβ plaques appearing prior to tangles, which are extensive in older transgenic mice.

    “Both Aβ and tau exhibit age- and region-dependent formation in these mice, with Aβ plaques appearing prior to tangles, which are extensive in older transgenic mice.”

    From Brain microstructure abnormalities in the 3xTg-AD mouse – A diffusion MRI and morphology correlation study (2022) · cites this paper as [4]

    The Results section (page unavailable) describes age-dependent Aβ accumulation in the hippocampus and reports early tau pathology at 6 months and advanced tangles at 20 months. It does not establish that plaques appear before tangles or that both Aβ and tau formation are region-dependent; its explicit timing comparison is between Aβ oligomers and plaques. (LLM, conf=0.84)

  • Aβ plaque and tau pathology are evident in 15-month-old TG mice, and significantly increased with age.

    “In our morphological analysis (Fig. 2 and 3), as previously described [3–6, 28], Aβ plaque and tau pathology are evident in 15-month-old TG mice, and significantly increased with age (online supplementary Fig.1 and 2).”

    From Brain microstructure abnormalities in the 3xTg-AD mouse – A diffusion MRI and morphology correlation study (2022) · cites this paper as [4]

    The Results section (page unavailable) describes age-related Aβ accumulation in 3xTg-AD mice and tau pathology that is apparent by 6 months and advanced by 20 months. It does not specifically assess 15-month-old mice or establish a statistically significant age-related increase in both plaques and tau pathology; the citing sentence points to its own figures for that finding. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • The 3xTg-AD mouse develops both amyloid-β and neurofibrillary tangles in a temporal and spatial pattern similar to human AD pathology.

    “It develops both amyloid-β (Aβ) and neurofibrillary tangles in a temporal and spatial pattern similar to human AD pathology [3–6].”
  • Due to the variability of the degree of AD pathology described in this model, large ROIs, as used for the HD and HV, may have attenuated some effects.

    “Additionally, due to the variability of the degree of AD pathology described in this model [4, 6, 26], large ROIs, as used for the HD and HV, may have attenuated some effects.”

    From Brain microstructure abnormalities in the 3xTg-AD mouse – A diffusion MRI and morphology correlation study (2022) · cites this paper as [4]

    The section on age-dependent oligomer accumulation describes changes in pathology with age and within the CA1/subiculum, but does not report variability in the degree of AD pathology among mice in this model. Searches for variability, differences among animals, and regional heterogeneity found no passage establishing the premise attributed to this source. The suggestion that large ROIs attenuated effects is the citing authors’ own inference. (LLM, conf=0.70)

    Experimental — accuracy not yet measured
  • Antibodies can reverse intracellular tau and synapse pathology and provide cognitive benefits.

    “the ability of antibodies to reverse intracellular tau and synapse pathology (Chauhan et al., 2008; Oddo et al., 2006) and to provide cognitive benefits (Hillen et al., 2010; Takamura et al., 2011).”

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.
