An anti-inflammatory neuroenhancer mitigates amyloid-β pathology to improve Alzheimer's disease therapy.

ABSTRACT: β-amyloid (Aβ) inhibition significantly attenuates the early-stage Alzheimer's disease (AD) progression, but the improvement in cognitive function remains limited by neuroinflammation. Here, we developed a bioinspired neuroenhancer that concurrently targets both Aβ aggregation and neuroinflammation. Rutin and small interfering RNA targeting beta-site amyloid precursor protein cleaving enzyme 1 (siBACE1) were co-loaded into the calcium phosphate core, which was further coated with lipid bilayers and Angiopep-2/rabies virus glycoprotein 29 peptides to form the multifunctional neuroenhancer (RB@LCP-AR). RB@LCP-AR not only releases siBACE1 to silence BACE1 expression and block Aβ production from the cleavage of amyloid precursor protein, but also releases Rutin to suppress the Aβ aggregation.
