Neuroimmunology is the most rapidly advancing field of research in the study of brain diseases and particularly in Alzheimer’s disease. We are studying how immune cells interact with the brain during Aging, in Alzheimer’s disease and in individuals with Down syndrome. We also study the mechanistic link between pregnancy with a Down syndrome fetus and the elevated risk of maternal cognitive decline.
