Abstract

Apolipoprotein E (apoE) and apoE/amyloid‐β (A β) transgenic (Tg) mouse models are critical to understanding apoE‐isoform effects on Alzheimer′s disease risk. Compared to wild type, apoE−/− mice exhibit neuronal deficits, similar to apoE4‐Tg compared to apoE3‐Tg mice, providing a model for A β‐independent apoE effects on neurodegeneration. To determine the effects of apoE on A β‐induced neuropathology, apoE−/− mice were crossed with A β‐Tg mice, resulting in a significant delay in plaque deposition. Surprisingly, crossing human‐apoE‐Tg mice with apoE−/−/A β‐Tg mice further delayed plaque deposition, which eventually developed in apoE4/A β‐Tg mice prior to apoE3/A β‐Tg. One approach to address h APOE‐induced temporal delay in A β pathology is an additional insult, like head injury. Another is crossing human‐apoE‐Tg mice with A β‐Tg mice that have rapid‐onset A β pathology. For example, because 5xFAD mice develop plaques by 2 months, the prediction is that human‐apoE/5xFAD‐Tg mice develop plaques around 6 months and 12 months before other human‐apoE/A β‐Tg mice. Thus, tractable models for human‐apoE/A β‐Tg mice continue to evolve.

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

  • Female mice were excluded from this initial study for consistency, as apoE isoform-specific interaction with Aβ are known to be influenced by gender.

    “Female mice were excluded from this initial study for consistency, as apoE isoform-specific interaction with A␤ are known to be influenced by gender (for review (44)).”

    From APOE4-specific Changes in Aβ Accumulation in a New Transgenic Mouse Model of Alzheimer Disease (2012) · cites this paper as [44]

    Sections 2.3 and 2.4 report that apoE isoform-related cognitive effects differ between female and male mice, supporting the general concern about sex differences. Sections 3.3 and 3.5 discuss isoform-specific Aβ pathology but do not establish that the apoE–Aβ interaction itself differs by sex. The paper also does not address the citing study’s decision to exclude female mice. (LLM, conf=0.82)

  • In APP transgenic mouse models, genetic expression of human APOE4 promotes Aβ seeding, accelerates Aβ oligomerization and deposition in the brain.

    “In APP transgenic mouse models, genetic expression of human APOE4 was found to promote Aβ seeding, accelerate Aβ oligomerization and deposition in the brain [455, 456].”

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.
