Nattokinase, Serrapeptase (2009, '13, '17, '18) & Alzheimer's
Nattokinase is an enzyme extracted from a food produced by fermenting soybeans with Bacillus natto. Serrapeptase is a enzyme that breaks down proteins produced by the non-pathogenic enterobacterium Serratiaare. Both are available as nutritional supplements and may have applications as part of Alzheimer's (AD) therapy.
In animal models of AD either nattokinase or serrapeptase improves brain metabolism, increases brain-derived neurotrophic factor and insulin-like growth factor levels, increases the expression of relevant genes (ADAM9 and ADAM10), has neuroprotective value, reduces neuroinflammation, and therefore may have a therapeutic value in AD therapy. Tests of nanoencapsulation delivery find that nattokinase is able to reduce amyloid aggregation and reduce fibril formation. It is also associated with improved learning and memory and learning in animals.
