Human lysozyme inhibits the in vitro aggregation of Aβ peptides, which in vivo are associated with Alzheimer's disease

Alzheimer's disease is a neurodegenerative disorder characterized by accumulation of A beta peptide aggregates in the brain. Using ThT fluorescence assays, AFM imaging, NMR and CD spectroscopy, and MD modeling we show that lysozyme - a hydrolytic enzyme abundant in human secretions - completely inhibits the aggregation of A beta peptides at equimolar lysozyme : A beta peptide ratios.
