The body's immune system could be harnessed to fight back against Alzheimer's disease, research suggests. Turning off a part of the immune system cleared away harmful brain deposits and improved memory, the mouse study found. US scientists, reporting their discovery in the journal Nature Medicine, said it was like a "vacuum cleaner" had been working in the brain. The Alzheimer's Society said more research would reveal if the process also worked in humans.
