Gut microbes in health and disease

I am the recipient of a Fellowship to work mainly at the Antigen Presentation Research Group at Imperial College London, Northwick Park & St Mark’s Hospital, which has strong collaborative links with the Quadram Institute Bioscience; my fellowship is funded by NHS R&D and I hold an Honorary Senior Lectureship at Imperial College London.

My background is in studies of immune regulation in inflammatory diseases, having previously worked in asthma and allergy research at King’s College London.

I am now applying my experience of immune activity in allergy and asthma to study of immunity in the gut mucosa. I am characterizing T cells and dendritic cells that reside in the colonic tissues of healthy people and comparing them with those from patients with inflammatory bowel disease (IBD). These cells can develop specificity for gut bacteria and my research is investigating this immunity to bacterial populations or their products in the gut in health.

A major aim is not only to understand bacterial immunity in health but also to make comparisons with immunity in IBD or colorectal cancer where bacterial communities in the gut are altered. Studies in mouse models at the Quadram Institute Bioscience will then be based on the human ex vivo studies. Our aim is to develop vaccines or bacterial therapy that could be used to promote health, to treat patients with IBD, or in the prevention/treatment of colorectal cancer.
