Marc Parmentier's group

Research themes

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.

Deorphanization of G protein-coupled receptor

More than hundred GPCRs are orphan, meaning that they have no known ligand, and often no known biological function. We are searching for the natural ligands of these orphan receptors starting essentially 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 more than a dozen receptors, including the thyrotropin receptor, adenosine receptors, the chemokine receptor CCR5 and the chemoattractant receptors ChemR23 and FPR3.

Characterization of GPCRs in the immune and central nervous systems

A number of specific receptors, among which several receptors identified by the group, are being studied in details in order to determine their role in physiological processes and diseases. This involves in vitro analysis of receptor pharmacology and ligand processing, distribution studies, as well as the analysis of knock-out and transgenic models. Among these, receptors for the leukocyte chemoattractant protein chemerin are being studied for their role in inflammatory processes and tumorigenesis.

Delineation of the functional role of GPCR heterodimerization

Most, if not all, GPCRs are able to form dimers or higher order oligomers. We have contributed to the demonstration that chemokine receptors form both homo- and hetero-oligomers, and demonstrated that oligomerization often involves allosteric interactions between oligomer subunits, changing thereby the pharmacology and/or signaling properties of individual receptors. We continue to study the functional consequences of GPCR oligomerization in terms of pharmacology and G protein coupling specificity.
