Abstract

Significance The accumulation of amyloid-β (Aβ) proteins in the brain contributes to Alzheimer´s disease (AD). Reducing Aβ by inhibiting its production with a β-secretase (BACE) inhibitor represents a novel mechanism for treating AD; however, whether this therapeutic strategy is capable of repairing impaired brain circuits associated with AD is unknown. Here we demonstrate that BACE inhibition is beneficial to all levels of impairment in an AD mouse model: cellular, long-range circuitry, and memory. We provide evidence that the rescue is dependent on the reduction of soluble forms of Aβ surrounding amyloid plaques. These results have mechanistic and therapeutic implications for AD, including Aβ-related memory defects.

  • The early abnormal neuronal hyperactivity phenotype in AppNL-G-F mice has been shown to be dependent on soluble amyloid beta.

    “which has been shown to be dependent on soluble Aβ [38–40]”

    From Selective suppression of oligodendrocyte-derived amyloid beta rescues neuronal dysfunction in Alzheimer’s disease (2024) · cites this paper as [38]

    The Results report that soluble, prefibrillary Aβ mediates neuronal hyperactivity: after BACE inhibition, applying Aβ dimers caused hyperactivity to recur. However, Materials and Methods identifies the mice as APP23xPS45, aged over 6 months with widespread Aβ pathology. The paper does not establish this dependence for the early phenotype in AppNL-G-F mice. (LLM, conf=0.88)

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.
