Professor Peter Bradding

Professor of Respiratory Medicine

Profile

I completed my research degree (DM University of Southampton) in 1995 and was awarded a competitive Wellcome Trust Advanced Fellowship in 1998 investigating ion channel expression and function in human mast cells. I was awarded a personal Chair in Respiratory Medicine at the University of Leicester in 2006. My laboratory has contributed major advances in the fields of mast cell and ion channel biology particularly in relation to asthma and pulmonary fibrosis and also with respect to the pathophysiological mechanisms of asthma. My research work is highly cited (H-index 76 >25000 citations). I also have extensive experience designing and running interventional clinical trials in asthma both industry- and investigator-led. I am an active Respiratory clinician focussing on the management of people with severe asthma.

Research

Research activities

• Investigating the molecular pathways driving type2 cytokine biomarker-high and -low severe asthma

• Ion channel regulation of human mast cell lung fibroblast and airway smooth muscle cell biology in asthma and lung fibrosis

• Regulation of human airway smooth muscle β2-adrenoceptor and steroid responsiveness by mast cells

• Modelling fibrosis in ex vivo human lung tissue for the assessment of novel therapies in lung fibrosis

• Ion channel regulation of fibroblasts in aortic stenosis and left ventricular fibrosis Current funding from NIHR MRC Midlands Asthma and Allergy Research Association (MAARA) industry
