The Peterson Lab
Graduate Students and Post Doctoral Fellows in the lab are working on research that is focused on the molecular underpinnings of autoimmune diseases, including rheumatoid arthritis, lupus, and myositis. The 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.

Post Doctoral Fellows
Shelly Tien, M.D., M.P.H.
Fellowship dates: 2013-15
Research Emphasis: Studied the immunologic responses in pregnancy. Specifically, she was interested in whether genetic variations in the PTPN22 gene impart discrepancies in immunologic markers, as well as clinical outcomes, in pregnant women given the influenza vaccine.
Yaya Wang, Ph.D.
Laboratory of Erik Peterson
Research Emphasis/Publications: Research was focused on a functional genomics project examining the role of an autoimmunity-associated gene in host-pathogen interactions. Her work demonstrated that the human disease “risk” gene PTPN22 functions as a positive regulator of TLR signaling and TLR-induced type 1 interferon-dependent immunity, including host antiviral response and suppression of inflammation in arthritis and colitis.
