Effective screen for amyloid β aggregation inhibitor using amyloid β-conjugated gold nanoparticles

The abnormal aggregation of amyloid β (Aβ) and its subsequent intra- and extracellular accumulation constitute the disease-causing cascade of Alzheimer's disease (AD). The detection of Aβ aggregates and senile plaque formation, however, is nearly impossible during early pathogenesis, and the absence of a convenient screen to validate the activity of Aβ aggregation regulators impedes the develop...

Naked-eye detection of amyloid aggregates using gold nanoparticles modified with amyloid beta antibody.

We developed a rapid method for estimating the amyloid beta (Aβ)-conformation state related with Alzheimer's disease. We prepared gold nanoparticle (AuNP)-Aβ antibody conjugates treated with bovine serum albumin to stabilize their dispersibility in a buffer. The prepared AuNPs were precipitated in the presence of Aβ aggregates, such as oligomers and fibrils. Aβ monomers did not precipitate AuNP...

Gold Nanoparticles and Microwave Irradiation Inhibit Beta-Amyloid Amyloidogenesis

Peptide-Gold nanoparticles selectively attached to b-amyloid protein (Ab) amyloidogenic aggregates were irradiated with microwave. This treatment produces dramatic effects on the Ab aggregates, inhibiting both the amyloidogenesis and the restoration of the amyloidogenic potential. This novel approach offers a new strategy to inhibit, locally and remotely, the amyloidogenic process, which could ...

Halogenation Generates Effective Modulators of Amyloid-Beta Aggregation and Neurotoxicity

Halogenation of organic compounds plays diverse roles in biochemistry, including selective chemical modification of proteins and improved oral absorption/blood-brain barrier permeability of drug candidates. Moreover, halogenation of aromatic molecules greatly affects aromatic interaction-mediated self-assembly processes, including amyloid fibril formation. Perturbation of the aromatic interacti...
