Autoimmunity is a central feature of many rheumatic diseases, such as systemic lupus erythematosus, rheumatoid arthritis, and dermatomyositis. The Autoimmunity Branch was established to address the cellular and molecular basis of autoimmunity. A number of work groups have been established within the Autoimmunity Branch to investigate specific aspects of immune cell function as they may pertain to the etiology of autoimmunity.
