A team of researchers from Université Laval, CHU de Québec, and pharmaceutical firm GlaxoSmithKline (GSK) has discovered a way to stimulate the brain's natural defense mechanisms in people with Alzheimer's disease. This major breakthrough, details of which are presented today in an early online edition of the Proceedings of the National Academy of Sciences (PNAS), opens the door to the development of a treatment for Alzheimer's disease and a vaccine to prevent the illness. One of the main characteristics of Alzheimer's disease is the production in the brain of a toxic molecule known as amyloid beta. Microglial cells, the nervous system's defenders, are unable to eliminate this substance, which forms deposits called senile plaques.
