Mechanism / pathway

  1. APOE
  2. Alzheimer's disease

Evidence for (4)

  • LXR agonists restore ApoE lipidation in glia and reduce tau/lipid accumulation in ApoE4 mice, providing direct proof-of-concept that lipidation enhancement is therapeutically tractable.

    PMID:37995685 2024 Neuron

  • ApoE4 impairs ABCA1 membrane trafficking in astrocytes, reducing cholesterol efflux and limiting APOE lipidation — the mechanistic deficit targeted by lipidation enhancement therapy.

    PMID:31641056 2019 Journal of Neuroscience

  • CSF lipoprotein-mediated cholesterol delivery to neurons is impaired in Alzheimer brain, implicating glial lipid efflux pathways as a disease-modifiable target.

    PMID:40701521 2025 Journal of Lipid Research

  • Inhibiting ACAT1/SOAT1 cholesterol esterification in ApoE4 mice shifts brain lipid homeostasis and reduces neurodegeneration-associated markers.

    PMID:39769453 2024 International Journal of Molecular Sciences
