Abstract

Apolipoprotein E (apoE) alleles determine the age-adjusted relative risk (ɛ4 > ɛ3) for Alzheimer's disease (AD). ApoE may affect AD pathogenesis by promoting deposition of the amyloid-β (Aβ) peptide and its conversion to a fibrillar form. To determine the effect of apoE on Aβ deposition and AD pathology, we compared APP V717F transgenic (TG) mice expressing mouse, human, or no apoE (apoE −/− ). A severe, plaque-associated neuritic dystrophy developed in APP V717F TG mice expressing mouse or human apoE. Though significant levels of Aβ deposition also occurred in APP V717F TG, apoE −/− mice, neuritic degeneration was virtually absent. Expression of apoE3 and apoE4 in APP V717F TG, apoE −/− mice resulted in fibrillar Aβ deposits and neuritic plaques by 15 months of age and substantially (>10-fold) more fibrillar deposits were observed in apoE4-expressing APP V717F TG mice. Our data demonstrate a critical and isoform-specific role for apoE in neuritic plaque formation, a pathological hallmark of AD.

  • APOE exerts toxic effects on the cerebrovascular system and neurons and influences Aβ clearance, amyloid deposition, and tau-related neurodegeneration in an allele-dependent manner APOE4 > APOE3 > APOE2.

    “APOE exerts toxic effects on the cerebrovascular system (694) and neurons (383, 384) and influences A 𝛃 clearance (60, 64, 98, 135, 256, 266, 278, 294, 315, 693), amyloid deposition (39, 256, 258, 266, 278, 314, 518, 612), and tau-related neurodegeneration (533) in an allele-dependent manner APOE4 > APOE3 > APOE2 .”

    From Blood-Brain Barrier: From Physiology to Disease and Back (2019) · cites this paper as [256]

    The Results section reports greater Aβ deposition in apoE4-expressing than apoE3-expressing mice, supporting the amyloid-deposition portion for which this paper is cited. The study compares apoE3 and apoE4, not apoE2, so it does not establish the full APOE4 > APOE3 > APOE2 ranking. The other effects in the sentence have separate citations and are not attributed to this paper. (LLM, conf=0.88)

  • Human apoE isoform-dependent differences in amyloid plaque deposition in APP-transgenic mice follow the pattern E4 > E3 > E2.

    “we and others have reported human apoE isoform-dependent differences in amyloid plaque deposition in APP-transgenic mice (E4 > E3 > E2) (10-14).”

    From Human ApoE isoforms differentially regulate brain amyloid-β peptide clearance (2011) · cites this paper as [10]

    The Results section reports greater Aβ deposition and more fibrillar plaques in apoE4- than apoE3-expressing APP-transgenic mice. The Methods section describes comparisons of apoE3 and apoE4 mice, but not apoE2 mice; this paper therefore supports E4 > E3, not the full E4 > E3 > E2 ranking.

  • Co-deposition of apoE in Aβ plaques is a prerequisite for the occurrence of focal neuritic dystrophy.

    “It has been previously demonstrated that co-deposition of apoE in Aβ plaques is a prerequisite for the occurrence of focal neuritic dystrophy [22,29].”

    From Blocking the apoE/Aβ interaction ameliorates Aβ-related pathology in APOE ε2 and ε4 targeted replacement Alzheimer model mice (2014) · cites this paper as [29]

    In Results (‘Neuritic Plaque Formation Requires apoE Expression’; page unavailable), the paper reports that mice lacking apoE developed substantial Aβ deposits but very few to no neuritic plaques. It also notes that apoE colocalizes with fibrillar Aβ. These findings support a role for apoE in plaque-associated dystrophy, but do not establish that apoE co-deposition in each plaque is an absolute prerequisite for focal neuritic dystrophy. (LLM, conf=0.87)

  • Co-deposition of apoE in Aβ plaques promotes focal neurodegeneration in humans and in AD Tg mice.

    “It has also been recognized that co-deposition of apoE in Aβ plaques promotes focal neurodegeneration in humans and in AD Tg mice [22,29,35].”

    From Blocking the apoE/Aβ interaction ameliorates Aβ-related pathology in APOE ε2 and ε4 targeted replacement Alzheimer model mice (2014) · cites this paper as [29]

    The Abstract and Results report that apoE expression is required for extensive plaque-associated neuritic degeneration in AD transgenic mice. The Results also describe apoE in human AD plaques and dystrophic neurites around human fibrillar Aβ deposits, but do not establish that apoE co-deposition promotes degeneration in humans. (LLM, conf=0.86)

  • In several AD Tg mouse models, lack of apoE is associated with absence of fibrillar Aβ deposits and prevented neurodegeneration.

    “Our findings remain consistent with the effects of apoE knock-out noted in several AD Tg mouse models, where lack of apoE was associated with absence of fibrillar Aβ deposits and prevented neurodegeneration [13,29,31,32].”

    From Blocking the apoE/Aβ interaction ameliorates Aβ-related pathology in APOE ε2 and ε4 targeted replacement Alzheimer model mice (2014) · cites this paper as [29]

    The Results section reports that apoE-knockout APPV717F mice had virtually all thioflavine-S-negative Aβ deposits and very few to no neuritic plaques. The Abstract says Aβ-associated neuritic degeneration was virtually absent. This supports the pattern in one transgenic model, but not an absolute absence of fibrillar deposits or prevention of neurodegeneration more broadly. (LLM, conf=0.84)

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.
