Endothelin

Endothelin is a powerful chemical messenger produced by cells lining blood vessels that plays a crucial role in regulating blood pressure and blood flow throughout your body. This tiny protein works by binding to receptors on surrounding cells, causing blood vessels to constrict or relax depending on the body's needs. When endothelin levels become imbalanced, it can contribute to serious health conditions like high blood pressure, heart disease, and kidney problems, making it an important target for medical research and treatment.
