Abstract

Amyloid beta (Aβ) aggregation is generally believed as the crucial and primary cause of Alzheimer's disease (AD). However, current Aβ-targeted therapeutic strategies show limited disease-modifying efficacy due to the irreversible damages in the late stage of AD, thus the treatment should be given before the formation of deposition and target primary Aβ species rather than advanced plaques. Herein, inspired by heat shock protein, a self-assembly nanochaperone based on mixed-shell polymeric micelle (MSPM) is devised to act as a novel strategy for AD prevention. With unique surface hydrophobic domains, this nanochaperone can selectively capture Aβ peptides, effectively suppress Aβ aggregation, and remarkably reduce Aβ-mediated cytotoxicity. Moreover, the formed nanochaperone-Aβ complex after Aβ adsorption can be easily phagocytosed by microglia and thereby facilitates Aβ clearance. As a result, the nanochaperone reduces Aβ burden, attenuates Aβ-induced inflammation, and eventually rescues the cognitive deficits of APP/PS1 transgenic AD mice. These results indicate that this biomimetic nanochaperone can successfully prevent the onset of AD symptoms and serve as a promising candidate for prophylactic treatment of AD.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Amyloidogenic proteins (Aβ) and tau are examples of heat-shock proteins (HSPs) that can both promote and inhibit the aggregation of misfolded proteins.

    “Amyloidogenic proteins (Aβ) and tau are two examples of heat-shock proteins (HSPs) that can both promote and inhibit the aggregation of misfolded proteins [37,101].”
  • Inadequate operation of HSP systems can lead to oxidative stress, mitochondrial dysfunction, and other pathological conditions that damage the body, cause neuronal death, and exacerbate dementia.

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.
