My research is dedicated to the study of neurodegenerative disease pathogenesis, including Alzheimer’s disease and so-called prion diseases. We have extensively characterized sporadic Creutzfeldt-Jakob disease in terms of clinical phenotype, pathological alterations, prion chemistry, and molecular genetics, and have found that specific features of the PrPsc molecule are remarkable predictors of phenotype. Further, we have recently characterized a form of human prion disease characterized by “protease-sensitive PrPsc,” expanding the spectrum of disease and drawing even closer overlap with more common neurodegenerative diseases. My studies on Alzheimer’s disease relate to early events in disease progression; as such, we have found a number of adducts related to oxidative stress in vulnerable, but pathologically normal, neurons in Alzheimer’s disease, as well as in control brains several decades prior to the onset of neurodegeneration. Our findings have significant implications in terms of therapeutic intervention.
