Method for producing a synthetic amylospheroids

Providing of a method for manufacturing a synthetic amylospheroids efficiency is improved. Comprising stirring a liquid containing amyloid β peptide in the presence of a plasticizer, synthetic amylospheroid manufacturing method. The amylospheroids, selectively function in mature neuronal speaking the aggregate of amyloid β peptides capable of inducing cell death. Amylospheroids is believed to play an important role in the pathogenesis of Alzheimer's disease and Lewy body dementia.
