Class switch recombination ( CSR ) requires activation-induced cytidine deaminase ( AID ) to trigger DNA double strand breaks ( DSBs ) at the immunoglobulin heavy chain ( IGH ) in B cells . Joining of AID-dependent DSBs within IGH facilitate CSR and effective humoral immunity , but ligation to DSBs in non-IGH chromosom... | The production of different classes of antibodies/immunoglobulins ( IgM , IgG , etc . ) is essential for protection against diverse pathogens and effective immunity .
