Neuropeptide Receptor Group

The Neuropeptide receptor laboratory studies G protein-coupled receptors (GPCRs) which represent the most important class of biomolecules for pharmaceutical development, being targeted by ~30 per cent of current drugs. Our studies on the structure and function of novel neuropeptide GPCRs will enable the development of new drugs to specifically target neurological and other diseases.

A glimpse at our research

Studies on G protein-coupled receptors; structure, function and drug development

Neuropeptides

The Neuropeptides Division primarily conducts multi-disciplinary studies on the relaxin family of peptides/hormones and their receptors. The division focuses on determining the role of these peptides and the receptors they target a wide range of physiological and disease states. These studies are coupled with fundamental drug discovery research on both these and other peptides and their G protein-coupled receptors. The aim of this research is to develop new biological knowledge and fundamental understanding about how to best therapeutically target these peptide systems with the long term view to develop drugs which target the peptide receptors to treat vascular, fibrotic, metabolic and psychiatric diseases.

An example of the success of this approach is the completion of a Phase III trial using the hormone relaxin for the treatment of acute heart failure by the Swiss Pharmaceutical Company Novartis. A Phase IIIb trial is ongoing and the relaxin drug, serelaxin, has been approved in Russia to treat patients with acute heart failure. Hence fundamental research on the mechanism of action of a hormone, in the case of relaxin pioneered at the Florey by the former Neuropeptides Division Head, Prof Geoffrey Tregear, can ultimately lead to its use to treat disease in patients.
