Following undergraduate studies at the University of Cambridge (BA St John's College, 1994), Nick Holliday obtained his PhD from King's College London (1998), supported by an AJ Clark PhD studentship from the British Pharmacological Society. During subsequent postdoctoral work in London, his interests in peptide messengers regulating appetite and metabolism became focused on molecular mechanisms underlying the signalling and regulation of their receptors. Nick was awarded a independent RCUK fellowship at the University of Nottingham in 2006, followed by Lecturer (2011) and Associate Professor (2013) positions. While at Nottingham, Nick's group has been funded by the MRC, charity, the Brazilian CAPES drug discovery program and industrial collaborations, and in 2011 he was awarded the Bill Bowman travelling lectureship from the British Pharmacological Society. He has also been actively involved in public engagement, including an arts crossover project to explain the use of imaging in pharmacology ("Hijacking Natural Systems"), funded by the Wellcome Trust.
GPCRs for peptides such as neuropeptide Y, gastrin releasing peptide and ghrelin, and nutrients such as free fatty acids, are implicated in the control of appetite, body weight and insulin secretion. They provide new drug targets to treat diabetes and obesity, and as such an understanding of the cellular mechanisms that regulate receptor function is crucial when considering long-term treatment of these conditions
Our group focuses on understanding the mechanisms underlying the signalling and intracellular trafficking of these GPCRs, and developing methods to assess ligand pharmacology for these processes. We have particular expertise in high content imaging and fluorescence / luminescence complementation approaches to develop GPCR protein-protein interaction assays, with the aim to study pharmacology at the level of individual signalling complexes and so better understand the effects of GPCR dimers and ligands which are signalling biased. Recently (in collaboration with Tom Bellamy), we are developing light (optogenetic) and "designer drug" activated receptors to explore spatiotemporal signalling in both model cell systems and astrocytes.
