Research Overview

     The focus of Dr. Ritchlin’s laboratory is directed towards understanding the mechanisms that underlie pathologic bone resorption and new bone formation in psoriatic arthritis and rheumatoid arthritis. Using a translational approach, investigators in his lab are analyzing the cell surface molecules expressed by osteoclast and dendritic cell precursors with the goal to identify susceptibility and response biomarkers in patients with inflammatory arthritis. The lab is also studying the effect of anti-TNF agents on dendritic cell differentiation in RA and PsA patients. In addition, collaborative studies are underway with the lab of Dr. Eddie Schwarz to understand the mechanisms that are responsible for bone marrow edema as recorded on magnetic resonance imaging scans in inflammatory arthritis. The bulk of this work is performed in animal models but insights gained from these studies are applied to the study of human joint diseases such as psoriatic and rheumatoid arthritis.
      Dr. Ritchlin is also the Director of the Clinical Immunology Research Unit.
      Dr. Ritchlin has mentored post-doctoral fellows and students in his lab in the past and continues to serve as a mentor for future scientists. He is very active in the Psoriatic Arthritis Clinic.
