Research in this Division focuses on immunity and inflammation and its consequences, and the genetic underpinning of gastrointestinal diseases.
Professor Kaser’s group investigates the mechanisms that underlie inflammation at mucosal surfaces. A single layer of intestinal epithelial cells – which may be considered the evolutionary most ancient innate immune cell type – separates the complex and densely populated habitat of the microbiota from the sterile host tissue of the gut, which itself harbours the majority of the host’s bona fide immune cells. A loss of the mutualistic relationship between host and microbiota is thought to be at the basis of the inflammatory bowel diseases Crohn’s disease and ulcerative colitis. Using a variety of techniques, including complex genetic models, we explore the major biological mechanisms that are affected by risk genes of inflammatory bowel disease. This approach opens up a window to explore the environmental factors that may trigger disease in genetically susceptible individuals, and which are the cause for the steep increase in incidence and prevalence of these diseases around the world. Following this path, we have reported mechanisms of how hypomorphic autophagy and mediators of the unfolded protein response lead to inflammatory bowel disease, defining a key pathway of Crohn’s disease pathogenesis.
Dr Parkes investigates the genetic basis of inflammatory bowel disease through genome-wide association studies, which are performed in collaboration with the Wellcome Trust Sanger Centre. He leads the UK IBD Genetics consortium and is the past founding chair of the international consortium, which has driven the discovery of now > 150 genetic loci associated with risk for IBD.
Professor Fitzgerald investigates methods of early detection of cancer of the oesophagus. Oesophageal cancers are the 8th most common cancer worldwide and the 6th most common cause of cancer death with only 15% surviving 5 years, and frequently develops from an inflammatory condition of the oesophagus, Barrett’s oesophagus. The laboratory develops methods to allow for efficient ways of screening for patients at risk for malignant transformation that overcomes the limitations associated with the currently available screening methods. Professor Fitzgerald holds her primary affiliation with the Dept of Oncology and the MRC Cancer Unit.
Further research topics covered in the Division are the genetic basis of chronic liver disease (primary sclerosing cholangitis and primary biliary cirrhosis), and the role of senescence in liver disease (Dr Alexander), liver transplantation (Dr Gimson), small bowel transplantation and intestinal failure (Dr Middleton and Dr Woodward), non-alcoholic fatty liver disease (Dr Allison), inherited liver disease (Dr Griffiths), and endoscopy (Dr Metz).
In translational research, multi-centre trials of novel biological therapies for IBD, which target specific immune functions, are pursued within the Division.
