  • Cholesterol loading with apoE caused the potassium channel TREK-1 to traffic to lipid clusters similar to APP, an effect reversed by mechanical force.

    “In separate studies, we saw that cholesterol loading with apoE caused the potassium channel TREK-1 to traffic to lipid clusters similar to APP (73, 74)—an effect that was reversed by mechanical force (75).”

    From Regulation of beta-amyloid production in neurons by astrocyte-derived cholesterol (2021) · cites this paper as [74]

    Citation (75) is attached to the mechanical-force reversal. In “Lipid domains and cholesterol-induced palmitoyl de-clustering” (page unavailable), the paper says shear force moves PLD2 out of GM1 lipid domains and links that movement to TREK-1 activation. It does not say force reverses apoE-induced trafficking of TREK-1 itself; the apoE-loading claim is attached to citations (73, 74), not this one. (LLM, conf=0.85)

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.
