Medical News Today - Protecting brain against Alzheimer's disease by enhancing the innate immune system, new strategy:
"The human body has its own defense against brain aging: the innate immune system, which helps to clean the brain of amyloid-beta waste products. However, UCLA researchers discovered that some patients with Alzheimer's disease have an immune defect making it difficult to clean away these wastes. This may lead to over-saturation of the brain with amyloid beta, which form amyloid plaques, the definitive hallmark of Alzheimer's disease."
