Prof Greaves read Microbiology at Bristol BSc (First Class honours) and was awarded a PhD in Biophysics and Biophysics and Molecular Biology at King’s College London (Winner of the Tadion-Rideal Medal). Postdoctoral research was undertaken at the Netherlands Cancer Institute in Amsterdam, the National Institute for Medical Research at Mill Hill in London and the Sir William Dunn School of Pathology in Oxford before being awarded a British Heart Foundation Basic Science Lectureship and subsequent election to a University Lectureship in Cell Pathology. In 2010 David Greaves was awarded the title of Professor of Inflammation Biology by the University of Oxford.
The Hertford Medicine teaching team is led by Professor David R. Greaves, an expert on inflammatory mediators and the resolution of inflammation. Prof. Greaves tutors first year Biochemistry & Medical Genetics, second year Principles of Pathology and third year modules in Cardiovascular Pathology and Inflammation Biology.
Prof Greaves is the Course Director of the British Heart Foundation Oxford 4-year DPhil course in Cardiovascular Science, which funds four 4-year DPhil studentships a year and he currently supervises two DPhil students in his laboratory.
Inflammation Biology – Acute Inflammation is the response of vascularised tissues to injury and infection. It is characterised by the rapid recruitment of plasma proteins and inflammatory cells called neutrophils from the bloodstream. This process is usually short lived and is followed by a period of inflammation resolution when with dead microbes, cell debris and apoptotic neutrophils are removed by cells called macrophages.
Chronic inflammation is characterised by continuing inflammation and the build up of large numbers of macrophages and T lymphocytes in diseased tissues such as the joints in rheumatoid arthritis. Work in my laboratory is aimed at understanding the key molecules that recruit and retain macrophages at sites of chronic inflammation and understanding the key mediators that initiate inflammation resolution. Recent work from the Greaves Lab on the resolution of inflammation has identified two new approaches to the development of novel anti-inflammatory drugs.
Cardiovascular disease – Angina, heart attacks and ischaemic strokes are all caused by the same underlying pathological process in arteries, atherosclerosis. Atherosclerosis is characterised by the build up of cholesterol containing lipoproteins and macrophages within the lining of major arteries. Professor Greaves and collaborators within the Department of Cardiovascular Medicine are studying the molecular mechanisms that regulate the very earliest stages of atherosclerosis and investigating factors with atherosclerotic plaques that affect macrophage differentiation. In collaboration with Professor Ed Fisher at new York University we are examining models of atherosclerotic plaque regression with a special emphasis on how macrophage responses to chemokines can be modified by diabetes and hypertension.
