Abstract

Four Auricularia polysaccharides (A.cornea (ACP), A.auricula (AAP), A.polytricha (APP) and M.fungus (MFP)) were researched to evaluate the effect of Auricularia species on digestion, anti-inflammatory and function of polysaccharides. The results showed that the molecular weights of ACP and MFP were significantly reduced in gastric juice from 30 min to 150 min (p < 0.05), the polysaccharides were degraded into small molecules and their structures were changed after digestion. The inhibition rate of α-amylase and α-glucosidase of APP were 71.21% and 82.01%, respectively, APP had a better hypolipidemic activity and the inhibitory activity was 89.5%. AAP, APP, and MFP could significantly promoted cell proliferation at 400 μg/mL. Four polysaccharides could inhibit inflammatory factors, so all polysaccharides have the good anti-inflammatory activity. The minimal inhibitory concentration (MIC) of APP against E. coli and S. typhi were 1.25% and 1.0%, respectively. There were significant differences in the digestion, anti-inflammatory and function of Auricularia polysaccharides among different species (p < 0.05).

Alzheimer's Disease: APP

Amyloid precursor protein (APP) proteolysis is critical for the development of Alzheimer's disease, a neurodegenerative disease associated with accumulation of amyloid plaques in the brain. Here is the latest research on APP and Alzheimer's disease.
