It is generally accepted that systemic autoimmune diseases such as systemic lupus erythematosus (EXE), mixed connective tissue disease, SjOgrens syndrome and polymyositis, are associated with the production of an extensive array of autoantibody specificities [1, 2]. As recently reviewed by Kofler et al,[3] and Bona [4], these autoantibodies use the same genetic elements and follow the same rules of gene rearrangement as conventional antibodies directed against foreign antigens. Despite such biochemical insights, the physiological mechanism (s) responsible for the activation and propagation of autoantibodyproducing B cells is still a topic of active controversy. Possibilities (not necessarily mutually exclusive) include:(1) polyclonal activation of all germ-line encoded V genes, including potentially autoreactive sequences;(2) selective activation of B cell subpopulations that express autoreactive germ-line sequences;(3) continued propagation of autoreactive B cells that arise as a result of somatic mutations within B cell clones responding to foreign antigens;(4) specific activation and antigen-driven selection of autoreactive B cells by self antigens, and (5) perturbation of the idiotype network, resulting in the stimulation of anti-idiotypic clones reactive with self-components. Assuming that all the above can result in production of auto&active antibodies, the more relevant question then becomes which of the above mechanisms generate pathogenic autoantibodies that reflect and/or contribute to the autoimmune disease process.
