Description of research and/or clinical interests: Dr. Longobardi’s research studies signal pathways involved in degenerative diseases, such as osteoarthritis (OA), as well as inflammatory and autoimmune diseases. Specifically, her main laboratory-based project focuses on the role of inflammatory chemokines and cytokines in joint tissue degeneration following trauma. Dr. Longobardi use a murine model of post-traumatic OA based on the destabilization of the medial meniscus and analyzes whether blockade of chemokine signaling by antagonizing their receptors at different times during the disease affects cartilage, bone and pain measurement post-injury. These findings are critical in arthritis research as they can lead to develop novel therapeutic approaches to treatment.
