Marc Parmentier

Our research

The group of Marc Parmentier is dedicated to the study of G protein-coupled receptors, particularly the characterization of new receptors and their ligands (“deorphanization”). G protein-coupled receptors (GPCR) represent the largest family among membrane receptors. They play a major role in a variety of physiological and pathophysiological processes, and constitute the targets for almost half the active compounds presently used as therapeutic agents. The objective of our group is to characterize novel signalling pathways involving GPCRs, determine their contribution to physiology, and their involvement in diseases. We focus on receptors expressed in the brain or the immune system.
More than hundred GPCRs are still orphan, meaning that they have no known ligand, and often no known biological function. We search for natural ligands of orphan receptors starting from natural sources, such as tissue extracts and biological fluids. Orphan receptors are expressed in cell lines amenable for fast screening of biological activities. When activities are identified, the bioactive compounds are purified and characterized. Such characterization usually opens a new chapter of physiology. Our group has over the years characterized over a dozen receptors, including the thyrotropin receptor, adenosine receptors, chemokine and chemoattractant receptors, and receptors for neuropeptides, such as nociceptin, kisspeptins and prolactin-releasing peptide. The function of receptors in physiological processes and diseases is analyzed by the use of transgenic and knock out mouse lines, as well as similar models in zebrafish.
