The apelin receptor APJ belongs to the family of seven-transmembrane domain receptors and is coupled to inhibitory G-proteins [1,2]. Apelin is synthesized as a 77 amino acid pre-pro-peptide that can be cleaved into fragments of different sizes that activate APJ [1,2]. Apelin peptides have been shown to affect many biological functions in mammals including the neuroendocrine, cardiovascular, and immune systems [1]. It can act via autocrine, paracrine, endocrine, and exocrine signalling [1].
In the cardiovascular system apelin has been shown to increase cardiac contractility when administered in pharmacological doses
