Systemic lupus erythematosus (SLE) is an autoimmune disease with unknown etiology. Periods of elevated disease activity, or SLE flares, cause significant organ damage, medication toxicity, and morbidity in patients. However, how a normally suppressed immune system mounts an aggressive autoimmune response that causes a flare is not known.
Our goal is to understand the mechanisms underlying the increase in autoimmune response and how cooperation between immune cells aggravates disease. Innate immune cells such as monocytes and neutrophils are the first cells to respond to infection or inflammatory events, and can therefore shape both a normal immune response to fight an infection as well as an autoimmune response. We utilize different approaches to understand the how these cells worsen the immune response in SLE. We aim to understand the role of a common viral infection on initiation of autoimmune response. We also study how this initial autoimmune response can influence the function newly generated immune cells, eventually cascading into an uncontrolled inflammatory response, which results in SLE flare.
Our studies will identify specific pathways that regulate flares and will lead to identification of new diagnostic markers as well as new targets for therapy.
