Cells talk more in areas Alzheimer’s hits first, boosting plaque component

Higher levels of cellular chatter boosts levels of amyloid beta in the brain regions that Alzheimer’s hits first, researchers at Washington University School of Medicine in St. Louis report. Amyloid beta is the main ingredient of the plaque lesions that are a hallmark of Alzheimer’s. The finding may help explain why areas that are most active when the brain rests are often among the first to develop these plaques, according to the researchers.
