Brain's immune system could be harnessed to fight Alzheimer's

The brain's immune system could potentially be harnessed to help clear the amyloid plaques that are a hallmark of Alzheimer's disease, new research suggests. The findings are the culmination of years of investigation after a surprising discovery while studying mouse models of Alzheimer's disease. Researchers observed that amyloid beta plaques -- which scientists believe play a major role in the disease -- were being cleared in animals with chronic brain inflammation.
