| Outline of Final Research Achievements |
Reducing Amyloid β (Aβ) protein and tau protein in the brain, which are closely related with Alzheimer’s disease, is supposed to be effective to suppress the disease. In this study, we generated two types of DNA vaccines targeting tau or Aβ plus tau. We administrated them to the triple transgenic mice having three mutations (amyloid precursor protein, tau and presenilin 1) associated with familial Alzheimer’s disease (B6;129-Psen1tm1Mpm Tg(APPSwe,tauP301L)1Lfa/Mmjax). As a result, anti-tau antibody was elevated in the tau vaccine-received mouse sera and anti-tau plus anti-Aβ antibodies were elevated in Aβ・tau vaccine-received ones. In addition, we observed the reduction of the amount of tau and Aβ proteins in the mouse brains. The results suggested that these vaccines were useful to suppress Alzheimer’s disease. They are patent-pending.
