Systemic Lupus Erythematosus is a systemic autoimmune disease affecting multiple organ systems including the kidney, joints, skin and brain. Renal failure is a major cause of morbidity in Lupus patients. Another autoimmune disease, Sjogren’s syndrome affects the saliva and tear producing glands. A characteristic feature of both these diseases is an immune response to intracellular proteins. I am interested in studying how the immune responses to these self-proteins are initiated; and how this activation of the immune system leads to organ damage.
The immune system is constantly responding to the environment, particularly to microbes present on skin and mucosal surfaces. We are currently investigating whether the microbes in the mouth or the gut can initiate autoimmunity and/or influence the severity of disease. This research into the interactions between the microbiota and the immune system will give us insights into disease mechanisms. It will give us some clues on why some patients develop worse kidney disease in Systemic Lupus Erythematosus or worse salivary gland dysfunction in Sjogren’s Syndrome.
