Ischaemia-Reperfusion Injury

A major theme in the Saeb-Parsy lab is investigation of the mechanisms of ischaemia-reperfusion injury (IRI) in transplantation and other disorders and development of novel therapeutic strategies. As part of the Mitochondrial Therapies Group, we have a long-standing collaboration with Dr Mike Murphy from the Cambridge MRC Mitochondrial Unit, Dr Christian Frezza from the MRC Cancer Unit, Dr Thomas Kreig from the Department of Medicine and  Prof Richard Hartley from University of Glasgow to study mitochondrial mechanisms of IRI and safety and efficacy of novel mitochondria-targeted therapeutics in transplantation, myocardial infarction and stroke.

Our fundamental approach is to simultaneously examine key IRI hypotheses using murine, porcine and human experimental models to enable accelerated translation. We utilise a comprehensive range of murine, porcine and human models of IRI, which include mouse heterotopic heart and kidney transplantation, and in close collaboration with Prof Mike Nicholson and Dr Sarah Hosgood from the Department of Surgery, ex vivo normothermic perfusion of porcine and human organs. We co-founded and coordinate the annual UK Ex Vivo Normothermic Perfusion Symposium, which aims to share expertise and encourage collaborations focused on the use of ex vivo organ perfusion in transplantation.
