Apelin also known as APLN is a peptide which in humans is encoded by the APLN gene.[ Apelin is the endogenous ligand for the G-protein-coupled APJ receptor that is expressed at the surface of some cell types.[7] It is widely expressed in various organs such as the heart, lung, kidney, liver, adipose tissue, gastrointestinal tract, brain, adrenal glands, endothelium, and human plasma.
