Doctors at Keck Medicine of USC are testing a new treatment that uses stem cells to produce dopamine in the brain. This could help slow down or even stop Parkinson's disease.

Parkinson's disease is a long-term condition that affects movement and motor function. It's caused by a drop in dopamine levels in the brain. Dopamine is a chemical messenger that helps with movement, memory, mood, and other essential functions.

Researchers at Keck Medicine of USC are working on a new approach to address this dopamine loss directly. They're implanting specially engineered stem cells into the brain. These stem cells are designed to replace damaged neurons and generate dopamine.

The treatment uses induced pluripotent stem cells (iPSCs), which can develop into many different kinds of cells in the body. The doctors believe that these iPSCs can reliably mature into dopamine-producing brain cells, offering the best chance of jump-starting the brain's dopamine production.

In an early phase clinical trial, doctors are implanting these stem cells into the brains of 12 people with moderate to severe Parkinson's disease. Participants will be closely monitored for 12-15 months to track changes in symptoms and watch for potential side effects.

The ultimate goal is to pioneer a technique that can repair patients' motor function and offer them a better quality of life.

Why It Matters

This new treatment could bring hope to millions of people worldwide living with Parkinson's disease. It also highlights the potential of stem cell therapy in treating neurological disorders.

Key Facts

• Over one million people in the United States are living with Parkinson's disease, and about 90,000 new cases are diagnosed each year.
• The treatment uses induced pluripotent stem cells (iPSCs), which can develop into many different kinds of cells in the body.
• Participants will be closely monitored for 12-15 months to track changes in symptoms and watch for potential side effects.
