Understanding Serotonin's Role in Mitral Valve Health and Repair
Serotonin Signaling in Mitral Valve Homeostasis, Maintenance and Restoration
This project looks at how a chemical called serotonin affects the heart's mitral valve, hoping to find new ways to treat a common valve problem.

What this research studies
Millions of people suffer from mitral regurgitation, a heart valve condition that currently has no medication to stop its progression, often requiring surgery. Our team is exploring how serotonin, a natural body chemical, and its related proteins, like the serotonin transporter (SERT), contribute to this valve disease. We've found that SERT levels are lower in diseased human mitral valves, which might lead to too much serotonin activity. We are also studying how mechanical stress on valve cells and certain medications might worsen the condition by affecting serotonin pathways. The goal is to uncover new drug targets that could prevent or slow down mitral valve damage.
Who could benefit from this research
Good fit: Patients with mitral regurgitation, especially those whose condition might be influenced by serotonin pathways or certain medications, could potentially benefit from future treatments developed from this research.
Not a fit: Patients whose mitral valve disease is not related to serotonin signaling or who require immediate surgical intervention may not directly benefit from this specific research direction.
Why it matters
Potential benefit: If successful, this work could lead to the first medications to prevent or slow the progression of mitral regurgitation, potentially reducing the need for surgery.
How similar studies have performed: Previous clinical and biological evidence from this and other groups has already shown a direct link between serotonin signaling and heart valve disease.
