Developing FLEXISyn to Identify and Measure Changes in Alpha-Synuclein in Parkinson's Disease with Judith Steen

The Michael J. Fox Foundation Parkinson's Podcast

New qualitative and quantitative tools are being developed to measure and track changes in proteins relevant for neurodegenerative disease, and these tools have the potential to accelerate drug discovery and clinical trials. In this episode, Dr. Judith Steen discusses her work creating novel qualitative and quantitative tools and workflows at the interface of proteomics and transcriptomics, including their novel FLEXI platform. This platform uses targeted, high- throughput quantitative mass spectrometry to isolate, quantify, and identify molecular changes in proteins. She describes her ongoing project, funded by The Michael J. Fox Foundation, to develop FLEXISyn, which aims to track post-translational changes in alpha-synuclein to better understand how the protein becomes dysfunctional and begins misfolding and forming toxic aggregations in Parkinson's disease. Judith is Associate Professor of Neurology at Harvard Medical School, a member of the Harvard Stem Cell Institute, and Director of the Neuroproteomics Laboratory in the F.M. Kirby Neurobiology Center at Boston Children's Hospital.

This podcast episode was part of a limited series created by The Michael J. Fox Foundation in 2023 and 2024 for clinicians and researchers in our audience. These episodes provide a deeper dive into exciting new scientific research in Parkinson’s disease, as well as innovative tools and valuable resources, through conversations with a variety of experts in the field. We hope you enjoy the conversation.

The Foundation’s landmark research study is exploring the connection between sense of smell and brain disease. People with and without Parkinson's can help by taking a free scratch-and-sniff test. Get yours at mysmelltest.org/request.
