Apelin Receptor Dimerization and Oligomerization

Apelin and its receptor are expressed in many tissues and play an important role in maintaining the homeostasis of the cardiovascular system and body fluids. Also, the association of this system with many diseases, such as diabetes, hypertension, obesity, cancer, diabetic retinopathy, etc., has been determined. This system is considered a therapeutic goal in many mentioned diseases. G protein-coupled receptors (GPCRs) have the ability to form oligomers and dimers with themselves and other receptors. The formation of these oligomers is associated with a change in the signaling pathways of the receptors. Research on the oligo and dimers of these receptors can revolutionize the principles of pharmacology. The apelin receptor (APJ) is also a GPCR and has been shown to have the ability to form dimers and oligomers. This article discusses the dimerization and oligomerization of this receptor with its own receptor and other receptors, as well as the signaling pathways.
