Scientists have presented a vaccine for the treatment of Alzheimer's

Scientists have developed a vaccine against Alzheimer's disease that can radically change the usual

treatment methods. She was able to change the atrophied brain matter of mice by blocking a protein that causes the disease. The study was published online in the British scientific journal Nature.

"To use the vaccine in humans,much more research is needed, but this achievement can already help develop a cure for dementia, ”said Haruhisa Inoue, a professor at Kyoto University and one of the authors of the study.

Alzheimer's disease and other forms of dementiacharacterized by abnormal accumulation of tau proteins in the brain. During the study, scientists managed to introduce the gene into a harmless virus to make it produce protein. Then they introduced the virus into mice along with genes that made them prone to dementia. The vaccine stimulated the immune system of mice, causing their organisms to create antibodies that eliminate tau proteins. Mice in which the vaccine was tested had twice as many antibodies as mice that were not given the vaccine.

In addition, brain areas of vaccinated micewere only two-thirds atrophied compared to mice that were not vaccinated at all. During eight months of observation of the mice, not a single side effect was recorded.

The Alzheimer's Association estimates that more than 5 millionAmericans over 65 years of age are living with this disease. This number is expected to triple by 2050. There is no cure for Alzheimer's disease, and some drugs help control symptoms, but none can completely cure the disease.
