SummarySomatic recombination and somatic hypermutation generate the diversity of the immunoglobulin (Ig) repertoire. Both mechanisms form Ig that recognize foreign antigens and also Ig that react with self-antigens. The frequency at which autoreactive Ig are made and where and when they are regulated to avoid autoimmunity is unclear. The generation of recombinant monoclonal antibodies from single isolated human B cells helps to answer these questions.
