| Outline of Final Research Achievements |
Rise of oxidative stress in the brain is enhanced by the aggregation of amyloid-beta protein and decrease of lipophilic antioxidants. This phenomenon is associated as one factor in the generation of Alzheimer's disease (AD). However, there is no certain treatment or cure for AD. This may be due to the blood brain barrier (BBB), which limits brain uptake of various bioactive compounds (including small molecules). Therefore, in the present study, we prepare the “lipophilic antioxidant encapsulated biodegradable nanoparticles” and challenge to improve brain lipophilic antioxidant concentrations (by decreasing oxidative stress in the brain) by oral intake.
