My research is focused primarily on understanding how to limit the loss of contractile tissue that occurs after MI, to prevent the stimulus for progression to heart failure. This includes tissue loss associated with acute ischaemia and the subsequent restoration of blood supply or reperfusion, but in particular the processes involved in infarct healing (neutrophils, macrophage polarisation, fibroblast activation & angiogenesis) and how these might be targeted therapeutically to prevent infarct expansion during repair. The mammalian myocardium retains regenerative capacity in the early post-natal period, my lab is studying the role of macrophages in growth and repair of the neonatal myocardium with a view to understanding how to enhance regenerative potential in the adult.
Current studies include investigation of intracellular glucocorticoid regeneration, interleukin-4 receptors, hydrogen sulphide metabolism and macrophage Wnt signallng.
Advanced in vivo imaging is key to identifying myocardial injury as well as in characterisation of structure, function and increasingly molecular processes during remodelling of the heart. The lab collaborates extensively with Medical Physicists supporting the Edinburgh Preclinical Imaging unit to optimise the use of high frequency ultrasound, magnetic resonance imaging (MRI), positron emission tomography (PET) and optical imaging (fluorescence molecular tomography in vivo and optical projection tomography in vitro) for more accurate identification of viable myocardium post-MI, as well as structural and functional characterisation in health and disease.

Gillian Gray obtained her B.Sc. with Honours in Pharmacology from the University of Aberdeen. Her Ph.D. studies at the University of Strathclyde with Brian Furman and James Parratt identified PAF and PGE2 as key mediators in sepsis induced hypotension and loss of vascular function. In 1988 Gillian took up a post-doctoral fellowship at the Université Louis Pasteur de Strasbourg, France with Jean-Claude Stoclet to continue studies of vascaulr dysfunction in sepsis. This lead to the first description of the role of inducible nitric oxide synthase (iNOS) in sepsis associated hypotension and vascular dysfunction (Gray et al.,1990. Br. J. Pharmacol. 103, 1218-1224). Gillian then joined the CV research group led by Martine Clozel at F. Hoffman-La Roche, Basel, Switzerland, studying receptors that mediated the effects of the newly described potent vasoconstrictor peptide, endothelin, and contributing to the development of the first non-peptide endothelin receptor antagonist (Clozel et al. 1993, Nature, 365, 759-761). The award of a British Heart Foundation Intermediate Fellowship allowed Gillian to come to the University of Edinburgh to initiate her own research focussed on investigation of endothelin receptors in heart failure. Gillian took up a lectureship in Pharmacology in 1995 and moved to the BHF/University Centre for Cardiovascular Science, Queens Medical Research Institute in 2005 where she is currently a Reader in Cardiovascular Pharmacology.
