Alpha-synuclein plays a key role in the pathophysiology of Parkinson's disease, and researchers have been investigating this protein as a therapeutic target and also as a potential biomarker for the disease. The alpha-synuclein seed amplification assay, developed by Dr. Claudio Soto and colleagues, leverages the self-replicating nature of the misfolded alpha-synuclein proteins that form aggregates in Parkinson's disease. Amplifying misfolded alpha-synuclein can allow researchers and clinicians to detect the presence of the pathological form of the protein in biospecimens, even when the amount of misfolded alpha-synuclein in a sample is very low. In this episode, Claudio discusses his work in this area and how it has opened the doors for a variety of potential uses of the alpha-synuclein seed amplification assay, including applications in diagnosis, clinical trials, and drug development for Parkinson's disease. This year, Claudio received the 2024 Robert A. Pritzker Prize for Leadership in Parkinson’s Research for his substantial contributions to research and his commitment to mentoring the next generation of scientists in the field. Claudio is the Huffington’s Distinguished University Chair, Professor of Neurology, and Director of the George and Cynthia Mitchell Center for Alzheimer’s Disease and Related Brain Disorders at The University of Texas Medical School in Houston. He is also the Founder, Vice-President, and Chief Scientific Officer at AMPRION Inc. This podcast is geared toward researchers and clinicians.
