Outline of Final Research Achievements

To identify blood-borne factors that are involved in cognitive impairment with diabetes, protein array and ELISA analyses using blood samples from DIO mice were performed, and then several factors altered were isolated.
On the other hand, we show that brain insulin signaling in amyloid-precursor protein knock-in (APPKI) mice that develop cognitive impairment after 6 months of age is also altered as well as DIO mice. Moreover, interestingly, we found that young APPKI mice that do not develop cognitive decline yet exhibit alteration in one of blood factors isolated in DIO mice. These data suggest that its- isolated factor may be a potential bio-marker which might predict the development of cognitive impairment, regardless of diabetes.
