A big step towards developing a vaccine against Alzheimer's disease

Injections of MPL, long used as an adjuvant (a substance that enhances the immune response during vaccination), led to the elimination of up to 80% of beta-amyloid plaques from the brains of mice with symptoms of Alzheimer's disease. Tests on the ability to solve new problems showed a significant improvement in the cognitive abilities of animals.
