Biography

James Leiper is Professor of Molecular Medicine in the School of Cardiovascular and Metabolic Health. Originally trained in molecular biology at the MRC Clinical Research Centre, James became interested in cardiovascular physiology whilst working with Professor Patrick Vallance in the Centre for Clinical Pharmacology at UCL and continued this work after taking up a position as Programme Leader at the MRC Laboratory for Medical Sciences. In 2017 James group was recruited to SCMH at the University of Glasgow where their research focus will be the translation of findings from basic science to human health and disease.

Research interests

Work in my laboratory is focussed on understanding the mechanisms that regulate nitric oxide (NO) signalling in health and disease. NO is a signalling molecule with protean functions in the cardiovascular, immune and central nervous systems. In the cardiovascular system dysregulated nitric oxide synthesis results in loss of cardiovascular homeostasis and contributes to a range of diseases including hypertension, atherosclerosis the cardiovascular collapse seen in septic shock. Therapeutic approaches to directly target NO have had limited success and therefore we have focussed on endogenous regulatory pathways that might facilitate therapeutically appropriate regulation of NO production. In particular we have focussed on understanding how endogenously produced inhibitors of NO synthesis might be harnessed therapeutically. To facilitate translation of our understanding of nitric oxide signalling for health care benefit we recently established a new biotech company backed by venture capital funding to perform clinical trials of new drugs for the treatment of septic shock.
