Osteoarthritis and Disease Modification: Where are We?
Richard Loeser, MD
April 12, 2023, at 7:00 am
Dr. Loeser’s primary research goal is to discover the basic mechanisms relevant to joint tissue destruction in osteoarthritis. Osteoarthritis (OA) is the leading cause of pain and disability in older adults. A better mechanistic understanding of OA is needed in order to develop interventions that can slow or stop disease progression before advanced joint tissue destruction occurs.
Dr. Loeser’s lab uses a combination of in vitro experiments using human joint tissue cells and in vivo experiments in rodent models to study cell signaling pathways that regulate anabolic and catabolic activity responsible for joint tissue remodeling and destruction. The lab is particularly interested in determining how reactive oxygen species regulate chondrocyte signaling downstream of integrins, cytokines and growth factors through the oxidation of specific cysteine residues in kinases and phosphatases as well as other intracellular proteins. The lab is studying how oxidative stress that occurs with aging and joint injury can alter the activity of these signaling pathways.
Dr. Loeser’s clinical research interest is in exercise and weight loss interventions for knee OA as well as the potential role of gut microbiota in OA. He has been involved in OA biomarker studies that have included metabolomics work and recently in a multidisciplinary effort to define OA phenotypes.

The School of Medicine of the University of North Carolina at Chapel Hill designates this live activity for a maximum of 0.5 AMA PRA Category 1 Credit(s)™. Physicians should claim only those hours of credit actually spent in the educational activity.
Other health professionals will receive a certificate of attendance from an AMA PRA Category 1™ activity. These certificates are accepted by the NC Boards for physician assistants, nurse practitioners, nurses, and respiratory therapists. Other health care providers may also be able to use these certificates, depending on their particular license requirements. (License requirements are subject to change. Participants should check with their licensing boards for specific questions. UNC and its partners are not responsible for changes in license requirements.)
This activity has been planned and implemented under the sole supervision of the course director and planning committee, in association with the UNC Office of Continuing Professional Development (UNC CPD).
