摘要

The immune system's ability to distinguish self and nonself is essential for both host defense against foreign agents and protection of self-antigens from autoim- mune destruction. Such discrimination is complicated by extensive structural homology shared between foreign and self antigens. One hypothesis to explain the development of an autoimmune response is that some B cells activated by foreign antigen acquire, through somatic mutation, specificity for both the eliciting foreign antigen and self antigen.
