Alzheimer's disease is a common cause of dementia, for which no disease-modifying therapy is yet available. Aβ3-10-KLH, a vaccine for active immunization, has been shown to prevent pathological changes in young transgenic models of AD, but the effects of treatment with it and its effects on mitochondrial dysfunction remain unclear. We immunized 6-month-old Tg-APPswe/PSEN1dE9 mice with Aβ3-10-KLH to analyze whether it is capable of eliminating amyloid-β after its appearance. The vaccine effectively decreased amyloid-β deposits, improved cognitive function and ameliorated mitochondrial dysfunction. These results indicate the potential of Aβ3-10-KLH as a vaccine to treat AD.
