The presence of apoE4, not the absence of apoE3, contributes to AD pathology

Abstract

ApoE is a component of several classes of lipoproteins regulating lipid metabolism and redistribution [42] and is detected primarily in astrocytes in rodents and in astrocytes and neurons in humans [7,26, 51]. Neuronal apoE levels increase after CNS injuries in humans and rodents [33,38]. The three human isoforms, E2, E3, and E4, (alleles e2, e3, e4) differ by cysteines at two positions (112 and 158) [92]. All other mammalian apoE is E4-like at these cysteine residues, but numerous other differences exist, particularly in the C-terminus, such that rodent apoE cannot be equated with any particular human apoE isoform in its sequence [94]. This is an important consideration when attempting to compare effects of mouse and human apoE in transgenic models. ApoE isoform-specific activities could impact neuronal function through several direct and indirect mechanisms [84], raising the possibility that apoE isoforms differ in the mechanism by which they impact AD pathology [73]. Since the position defended here is that the presence of E4 confers greater risk of AD, an appropriate question is how selection for such a risk factor might occur. The E3 allele has risen to prominence in the last

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.
