Research Summary/Interests

Research in the Peterson laboratory

Dr. Erik Peterson has strong interests in the molecular underpinnings of autoimmune diseases, including rheumatoid arthritis, lupus, and myositis. His laboratory utilizes genetic, biochemical, and primary human sample-based approaches to investigating the mechanisms whereby recently identified “risk” genes predispose to development of autoimmune disease. Dr. Peterson's group recently identified a role for Ptpn22, a potent “risk” gene for many autoimmune diseases, in the promotion of toll-like receptor signaling and type 1 interferon production. He is currently investigating the role of Ptpn22 in myeloid cell functions in systemic lupus and in responses to immunization, and is characterizing the molecular mechanism of Ptpn22 promotion of type 1 interferon signals.
