Abstract

Despite extensive efforts dedicated to developing therapies for Alzheimer's disease (AD), we still lack effective approaches capable of curing or halting its progression. Mounting evidence highlights the critical roles of dysfunctional microglia, which promote the abnormal accumulation of harmful protein deposits and initiate aggressive neuroinflammation, contributing to both the onset and advancement of AD. Hereby, we develop a brain-targeted ceria nanoparticle (T-CeNP), which exhibits both superoxide dismutase and catalase mimicking activities, for AD therapy. The functionalization of advanced glycation endproducts (RAGE) targeting peptide facilitates the blood-brain barrier (BBB) penetration of T-CeNP, prevents the formation of Aβ fibrils, and boosts Aβ degradation by microglia. By integrating the multifunctional RAGE targeting ligand and bioactive CeNPs, T-CeNP can effectively cross the BBB, quench the elevated reactive oxygen species, attenuate the activation of microglia, disrupt Aβ aggregation and promote its clearance in an AD mouse model, and slow down the progression of AD.

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.
