I am a clinician-scientist neurologist with interest in Alzheimer’s disease and other neurodegenerative dementias. My research focuses on trying to explain how the amyloid plaques and neurofibrillary tangles accumulate in the brain of Alzheimer’s disease patients and how they lead to dementia. I first approached this question by studying postmortem brain specimens from Alzheimer’s disease patients and healthy individuals under the microscope. The findings of my unbiased quantitative analyses supported an important role of glial (non-neuronal) cells, specifically astrocytes and microglial cells. These cells clearly react to plaques and tangles, but the consequences of this response remain largely unknown. Therefore, I became interested in understanding the underlying mechanisms of glial responses and their effects on Alzheimer’s disease development and progression.
Dr. Serrano-Pozo is originally from Málaga, Spain. He received his MD in 2001 at the University of Málaga School of Medicine and completed his neurology residency in 2006 at the University Hospital Virgen del Rocío in Seville (Spain), followed by a 2-year research and behavioral neurology fellowship at the same institution. He first joined Dr. Bradley Hyman’s lab at MGH as a research fellow in 2008, where he investigated clinic-pathological correlations of Alzheimer’s dementia using brain specimens from the Massachusetts Alzheimer’s Disease Research Center brain bank, as well as the National Alzheimer’s Coordinating Center (NACC) database. His publications during this period resulted in Dr. Serrano-Pozo obtaining his PhD at the University of Seville in 2013. Next, he pursued a US neurology residency, which he completed at the University of Iowa in 2017 as Chief Resident, before returning to MGH.
