Summary of research interest:

Our laboratory effort is focused on understanding scleroderma, also known as systemic sclerosis, and developing new therapeutic approaches based on identifying biomarkers of the disease process and utilizing biomarkers in clinical trials. Our group has a particular interest in understanding the mechanisms stimulating the immune response in the disease, focusing on innate immune responses leading to fibrosis and vascular injury. Our data show increased expression of interferon responsive genes in circulating monocytes of scleroderma patients, prompting current investigations into the stimulus for this pattern of gene expression and the effect of interferon on fibrosis and vascular injury. We are also investigating the pathogenesis through existing models of scleroderma, testing novel therapeutics in thee models and developing new murine models designed to clarify the relationship between innate immunity and fibrosis.
