Endothelin-1

Endothelin-1 (ET-1, EDN1) is the most potent endogenous vasoconstrictor; ETA/ETB receptor signaling drives sustained vasoconstriction, vascular remodeling, and fibrosis; bosentan and macitentan (dual ERAs) are first-line therapy for pulmonary arterial hypertension.

Also known as: endothelin-1, ET-1, EDN1, ETA receptor, ETB receptor, endothelin receptor antagonist, ERA, bosentan, macitentan, ambrisentan, pulmonary arterial hypertension, PAH
