Endothelin receptors

endothelin-receptors">Endothelin receptors are special proteins found on the surface of cells in the body that respond to a molecule called endothelin. When endothelin binds to these receptors, it triggers various bodily responses, primarily regulating blood vessel constriction and blood pressure. There are two main types of endothelin receptors, known as ETA and ETB, each with different functions. ETA primarily causes blood vessels to narrow, while ETB can help to relax them. Understanding these receptors is important for developing treatments for conditions like high blood pressure and heart disease.
