Research

Professor Smith’s group is based in the CIMR, and works on immune regulation and autoimmune and inflammatory disease.  This has focused on how naturally occurring variants in immune molecules such as FcγRIIB alter immune function and predispose to autoimmunity.  The accumulation of these risk variants in the population has been shown to be, at least in part, due to their ability to protect against infections such as malaria.  With Dr Lyons and in collaboration with Addenbrooke’s Vasculitis & SLE Clinic and the Division of Gastroenterology, Smith runs a translational programme studying the pathogenesis of human disease at the same time as looking for biomarkers.  A CD8T cell transcriptional signature has been found which predicts prognosis in autoimmune disease.  The European Vasculitis Genetics Consortium is also led from the laboratory.

Dr Clatworthy’s group is based within the Department of Medicine facility in the new LMB. We are interested in understanding how IgG antibodies and their receptors contribute to disease pathogenesis in autoimmunity, and to pathogen-associated and sterile inflammation, particularly in acute kidney injury.  Dr Clatworthy has also established a two-photon imaging facility, and is using this technology to investigate how IgG can impact on the dynamic behaviour of leucocytes. Clatworthy’s clinical interests are in antibody-mediated rejection and B cell modulation in renal transplantation.

Professor Patrick Maxwell’s group is based in CIMR and works on genetic renal diseases and cellular oxygen sensing.  He is supported by a Wellcome Trust Senior Investigator Award and is also Head of the School of Clinical Medicine.

Dr Bradley’s group has been studying the pathways involved in signaling by TNF-alpha family members in endothelial cells and their relevance to renal inflammation and transplant rejection.  He coordinates the Yale-Cambridge Research Initiative, and is the Director of the NIHR Cambridge Biomedical Research Centre.

Professor Ashcroft’s group is based in the Clifford Allbutt Building, and primarily focuses on elucidating the key regulatory mechanisms involved in hypoxia signalling in mammalian cells. The Ashcroft group has a strong interest in the hypoxia inducible factor (HIF) family of transcription factors and understanding their role in cancer, renal disease and other diseases. In particular, the Ashcroft group has been elucidating the role of mitochondria in oxygen sensing. In addition, Prof Ashcroft takes multidisciplinary collaborative approaches for leading the therapeutic development of novel small molecule hypoxia signalling targeting agents.
