Title: Characterisation and functional studies of the GPR1 transmitter system

Abstract: G-Protein coupled receptors (GPCRs) are important drug targets in many diseases, including cardiovascular disease. Recently discovered orphan GPCRs with unknown functions, like G-protein coupled receptor 1 (GPR1), could also prove to be successful drug targets. The BRIGHT study identified GPR1 as a candidate gene that corresponded to a region of interest in the genome-wide mapping of human loci for essential hypertension. In addition, the GPR1 gene was found to be regulated during a pivotal stage in the onset and progression of atherosclerosis. Chemerin is known to activate the CMKLR1 receptor; and has been proposed as the ligand for GPR1. Chemerin has also been implicated in the development of atherosclerosis.  

This research seeks to characterise the GPR1 signaling pathway in the cardiovascular system; distinguish the effects mediated by the two receptors through selective agonists and antagonists, and explore the role of GPR1 in atherosclerosis.
