What it is

A peptide hormone family that acts on the heart and blood vessels; studied as an infusion in heart and lung research.

Type: Peptide.

Definition (National Library of Medicine)

“A 77 amino acid secreted endogenous ligand for the angiotensin II receptor-like 1 protein (apelin receptor) that is proteolytically cleaved into four smaller peptides: Apelin-36, Apelin-31, Apelin-28, and Apelin-13. It inhibits entry of HIV into cells that express both apj and cd4 antigen and is highly expressed in breast milk, where it may modulate the neonatal immune response.”
