CLINICAL RESEARCH: Professor Fiona Powrie, of the University of Oxford and Oxford University Hospitals Trust, has been given an international prize for clinical research.

She is currently head of experimental medicine in the Nuffield Department of Medicine at John Radcliffe Hospital, where she works with the trust’s gastroenterology services.

Prof Powrie, who is also Sidney Truelove Professor of Gastroenteroloy at Oxford University, has been given the Louis-Jeantet Prize for Medicine, which recognises outstanding biological research with implications for the future of healthcare.

Her work focuses on why the immune system does not attack beneficial bacteria in the intestines.

She has identified a class of cells, called regulatory T cells, that police the immune response in the intestine, preventing it from attacking bacteria that are of benefit to us.

Prof Powrie’s team has demonstrated that deficiencies in these immune cells can lead to chronic intestinal inflammatory disease.
