Research Interests

We study factors governing the onset of autoimmunity and investigate strategies to restore self tolerance and repair damaged tissue. In terms of factors governing the onset of the autoimmune disease type 1 diabetes we have been particularly interested in the interrelationship between infection, autoimmunity and the genetic predisposition to autoimmune disease. Autoimmune diseases such as Type 1 diabetes are increasing in incidence in the developed world faster than can be acounted for by genetic change. Onset of Type 1 diabetes and most other autoimmune diseases is governed by both genetic and environmental factors. Our study of environmental factors has highlighted a key role for infection in reducing the incidence of Type 1 diabetes. We find that protection from diabetes arises through an interaction between the infectious agent and the innate immune system such that circuits which regulate the autoimmune response are reinforced. These studies are carried out in collaboration with Professor D Dunne (Microbiology and Parasitology) and Dr P Mastroeni at the Vet School.

Many genes influence the development of Type 1 diabetes. While some genes such as those encoding MHC class II molecules play a major role other genes have been more difficult to identify. Dr Jenny Nichols and I have generated NOD ES cells and these will be used to identify and characterise genes involved in diabetes development in NOD mice.
