| Outline of Final Research Achievements |
Neumerous epidemiological studies have suggested that type 2 diabetes is a risk factor of Alzheimer's diesase. However, the detailed underlying mechanism has been largely unclear. We previously showed that insulin resistance in central nervous system plays an important role of the pathogenesis of Alzheimer's diesase. In this study, we attempted to validate impaired insulin signal network occuring in brain of Alzheimer's disease by analyzing autopsied samples. By this analysis, we demonstrated that expressions of molecules associated with insulin signal were significantly altered, supporting the notion that insulin resistance is present in human brain of Alzheimer's disease.
