The Laboratory of Rheumatology, Autoimmunity and Inflammation together with the Affiliated Clinical Research Unit at the University Hospital, represent an interdisciplinary group of physician scientists, bio-scientists, clinicians and nurses that investigates medical inflammation in the context of autoinflammatory-autoimmune rheumatic diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and familial Mediterranean fever.
The laboratory explores mechanisms of breakdown of immune tolerance, tissue injury and repair with the ultimate goal of developing novel therapies. We use animal models of autoimmune diseases, as well as tissues obtained from humans to investigate innate and adaptive immune responses under the premise that they share common effector pathways for tissue injury. Importantly, we explore the relative contribution of these pathways in human diseases by studying well characterized patient cohorts seeking to identify molecular biomarkers for diagnosis and monitoring. We seek to understand how novel therapies work and explore molecular or genetic biomarkers that predict response or toxicity to therapy. We participate in local and international consortia in the context of competitive translational research projects.
