Gene-Based Therapies for Parkinson’s Disease

Substantial Matters: Life & Science of Parkinson’s

Gene-based therapies for Parkinson’s disease, while still in the developmental stage, are under active investigation. For this potential therapy, genes are engineered in a laboratory and then injected into specific parts of the brain. The genes may function either to induce cells in the brain to produce dopamine, or to code for the production of enzymes that then lead to the production of dopamine.

This episode is the second part of our conversation with Dr. Roger Barker, Professor of Clinical Neuroscience at the University of Cambridge in the United Kingdom. In our previous podcast with him, he discussed cell therapy for Parkinson’s. Here, he explains what gene-based therapy is, plans for the execution of the treatments, what symptoms they are aimed at, where the field currently stands, and how it compares to developments in cell-based therapies. As the field is still in the experimental stages, he again offers advice to people with Parkinson’s who are considering entering a clinical trial of gene-based or cell-based therapy and what they may expect in terms of symptom management and disease progression.
