title: Emerging role of the apelin system in cardiovascular homeostasis.
abstract: The angiotensin receptor-like 1 (APJ) and its novel ligand, apelin, share similarities in structure and anatomical distribution with that of angiotensin II and the angiotensin II type 1 receptor. However, apelin has positive inotropic, vasodilatory and diuretic properties. Differential expression and synthesis of apelin and the APJ receptor in normal and failing hearts suggest that the apelin system may contribute to the pathophysiology of human heart failure and has potential therapeutic use in treatment of heart failure.
