Most autoimmune diseases are driven (and potentially initiated) by the presence of pathogenic B and plasma cells as well as their secreted products, autoantibodies. My work centers on the role of human auto-reactive B cells in the pathogenesis of these diseases. We focus on rheumatoid arthritis and the immune response to post-translationally modified proteins as a model, and have a specific interest in the glycosylation of autoantibodies, in particular in the variable domain. My group has developed specific methodology to identify, isolate and characterize human auto-reactive B cells. We use this tool to understand mechanisms underlying the breach of tolerance to auto-antigens, and aim at developing ways for specific therapeutic targeting of pathogenic B cell memory.
