Bifunctional Inhibitor Lentinan Inhibits Fibrillogenesis of Amyloid-β Protein and α-Synuclein and Alleviates Their Cytotoxicity: In Vitro and In Vivo Studies.

Alzheimer's disease (AD) and Parkinson's disease (PD) are the two most common neurodegenerative diseases in the world. Misfolding of β-amyloid (Aβ) and α-synuclein (α-syn) and subsequent fibril formation are closely associated with the pathogenesis of AD and PD, respectively. Lentinan is a natural product commonly used in medicine and dietary supplements.

Ultrasound-Assisted Multi-Enzyme Extraction for Highly Efficient Extraction of Polysaccharides from .

polysaccharides present several physiological activities including antiviral, antitumor and anti-plasmodial effects. However, current processing usually results in low yields and high prices, thus lacking commercialization potential. The aim of this study was to develop an efficient method for the extraction of polysaccharides with high biological activity.
