Autoantibodies are produced by plasma cells and contribute to the pathogenesis of many diseases, including systemic or organ-specific autoimmune diseases that involve the kidneys. In contrast to short-lived plasma cells, long-lived plasma cells reside in survival niches in the bone marrow and inflamed tissue, and provide the basis of humoral memory and refractory autoimmune disease activity. Here, the authors discuss the generation of plasma cells, their role in autoimmune disease, and current and future strategies for the depletion of autoreactive plasma cells, including novel approaches that target humoral memory.
