title: Normal mice express idiotypes related to autoantibody idiotypes of lupus mice.
abstract: Spleen and fetal liver B cells of normal mice synthesized idiotypes shared by anti-DNA autoantibodies of genetically autoimmune mice. Some of the idiotypes were specific for DNA; the majority, however, were not. The findings indicate that the autoantibody idiotypes are related to a conserved family of antibody variable regions that are present in normal animals.
