Lithium‐Charged Gold Nanoparticles: A New Powerful Tool for Lithium Delivery and Modulation of Glycogen Synthase Kinase 3 Activity

Advanced Materials, EarlyView.
This study introduces glutathione‐stabilized gold nanoparticles for targeted lithium delivery (LiG‐AuNPs), enabling the controlled modulation of Glycogen Synthase Kinase‐3 (GSK‐3β). These non‐toxic, 2‐nm particles release lithium intracellularly, effectively inhibiting GSK‐3β in the brain without significant plasma lithium alterations.

Interaction of amyloid inhibitor proteins with amyloid beta peptides: insight from molecular dynamics simulations.

PLoS ONE, 2014
Knowledge of the detailed mechanism by which proteins such as human αB- crystallin and human lysozyme inhibit amyloid beta (Aβ) peptide aggregation is crucial for designing treatment for Alzheimer's disease.

Structure of amyloid-β (20-34) with Alzheimer's-associated isomerization at Asp23 reveals a distinct protofilament interface. [PDF]

, 2019
Amyloid-β (Aβ) harbors numerous posttranslational modifications (PTMs) that may affect Alzheimer's disease (AD) pathogenesis. Here we present the 1.1 Å resolution MicroED structure of an Aβ 20-34 fibril with and without the disease-associated PTM, L ...

Amyloid seeds formed by cellular uptake, concentration, and aggregation of the amyloid-beta peptide [PDF]

Proceedings of the National Academy of Sciences, 2009
One of the neuropathological hallmarks of Alzheimer's disease (AD) is the amyloid plaque, primarily composed of aggregated amyloid-beta (Aβ) peptide. In vitro, Aβ 1–42 , the major alloform of Aβ found in plaques, self-assembles into fibrils at micromolar concentrations and acidic pH.
