APOE ε2 is associated with increased tau pathology in primary tauopathy

Open access

Abstract

Apolipoprotein E ( APOE ) ε4 allele is the strongest genetic risk factor for late-onset Alzheimer’s disease mainly by modulating amyloid-β pathology. APOE ε4 is also shown to exacerbate neurodegeneration and neuroinflammation in a tau transgenic mouse model. To further evaluate the association of APOE genotype with the presence and severity of tau pathology, we express human tau via an adeno-associated virus gene delivery approach in human APOE targeted replacement mice. We find increased hyperphosphorylated tau species, tau aggregates, and behavioral abnormalities in mice expressing APOE ε2/ε2. We also show that in humans, the APOE ε2 allele is associated with increased tau pathology in the brains of progressive supranuclear palsy (PSP) cases. Finally, we identify an association between the APOE ε2/ε2 genotype and risk of tauopathies using two series of pathologically-confirmed cases of PSP and corticobasal degeneration. Our data together suggest APOE ε2 status may influence the risk and progression of tauopathy.

  • One study found that the APOEε2 allele is associated with increased odds of neuropathologically confirmed primary tauopathy (progressive supranuclear palsy and corticobasal degeneration).

    “One study found that the APOEε2 allele is associated with increased odds of neuropathologically confirmed primary tauopathy (PSP and corticobasal degeneration)66.”

    From Multifaceted roles of APOE in Alzheimer disease (2024) · cites this paper as [66]

    The Methods section confirms that the PSP and corticobasal degeneration cases met neuropathologic criteria. The Results section reports increased odds for the APOE ε2/ε2 genotype, not for carrying the ε2 allele generally; the increased odds for corticobasal degeneration in the full sample did not reach statistical significance.

  • The APOE ε2 allele is associated with increased tau pathology in the brains of human progressive supranuclear palsy.

    “Furthermore, the APOE ε2 allele was associated with increased tau pathology in the brains of human progressive supranuclear palsy, a primary tauopathy.”
  • APOE2 mice exhibited more tau pathology compared to APOE3 and APOE4 mice, and behavioral abnormalities in a tauopathy model.

    “For example, APOE2 mice exhibited more tau pathology, compared to APOE3 and APOE4 mice, and behavioral abnormalities in a tauopathy model.”
  • Hyperphosphorylated tau species, tau aggregates and behavioral abnormalities are observed in APOE ε2/ε2 mice.

    “Studies have shown that hyperphosphorylated tau species, tau aggregates and behavioral abnormalities were observed in APOE ε2/ε2 mice [471].”
  • APOE ε2 is associated with increased pathological tau levels in the presence of amyloid.

    “In addition, APOE ε2 is also associated with increased pathological tau levels in the presence of amyloid [471, 472].”

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.
