Apolipoprotein E and its receptors in Alzheimer's disease: pathways, pathogenesis and therapy

Open access
Bu, Guojun·2009·Nature Reviews Neuroscience

Abstract

The vast majority of Alzheimer's disease (AD) cases are late-onset and their development is probably influenced by both genetic and environmental risk factors. A strong genetic risk factor for late-onset AD is the presence of the epsilon4 allele of the apolipoprotein E (APOE) gene, which encodes a protein with crucial roles in cholesterol metabolism. There is mounting evidence that APOE4 contributes to AD pathogenesis by modulating the metabolism and aggregation of amyloid-beta peptide and by directly regulating brain lipid metabolism and synaptic functions through APOE receptors. Emerging knowledge of the contribution of APOE to the pathophysiology of AD presents new opportunities for AD therapy.

  • RAGE plays an important role in the uptake of Aβ by microglia.

    “RAGE is also reported to play an important role in the uptake of Aβ by microglia.333”

    From Role of neuroinflammation in neurodegeneration development (2023) · cites this paper as [333]

    The section “ApoE and apoE receptors in Aβ clearance and aggregation” describes receptor-mediated internalization of Aβ by microglia. It identifies apoE receptors, including LRP1, LDLR and VLDLR, but does not identify RAGE or establish its role in that uptake. Page numbers are unavailable in our copy. (LLM, conf=0.84)

  • In the brain and neuronal cultures, ApoE is synthesized in astrocytes.

    “In the brain and neuronal cultures, ApoE is synthesized in astrocytes.14,15”

    From Lipid Nanoparticle Delivery of siRNA to Silence Neuronal Gene Expression in the Brain (2013) · cites this paper as [15]

    The Biochemical properties section states that astrocytes are the predominant source of ApoE in the brain and describes ApoE particles secreted by cultured astrocytes. It does not specifically establish where ApoE is synthesized in neuronal cultures, and it notes that microglia also synthesize some ApoE. Page numbers are unavailable in our copy. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • ApoE4 lowers the age of onset of Alzheimer's disease.

    “lowers the age of onset [4–14]”

    From Neuronal Apolipoprotein E4 Expression Results in Proteome-Wide Alterations and Compromises Bioenergetic Capacity by Disrupting Mitochondrial Function (2019) · cites this paper as [5]

    The Introduction identifies ApoE ε4 as a major risk factor for late-onset Alzheimer’s disease and says its effect on risk is greatest between ages 60 and 70. It does not state that carriers develop Alzheimer’s at a younger age than noncarriers, so the specific age-of-onset claim goes beyond what the copy reports. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • ApoE is critical for brain cholesterol homeostasis and, produced primarily by astrocytes, delivers cholesterol and essential lipids to neurons by interacting with members of the LDLR family.

    “ApoE, critical for brain cholesterol homeostasis and produced primarily by astrocytes, delivers cholesterol and essential lipids to neurons by interacting with members of the low-density lipoprotein receptor (LDLR) family (21).”
  • Brain lipids transported by apoE/lipoprotein particles play critical roles in neuronal membrane homeostasis and synaptic functions.

    “Brain lipids transported by apoE/lipoprotein particles have been shown to play critical roles in neuronal membrane homeostasis and synaptic functions (21).”

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.
