    Author : Minghui He; Eva Severinson; Jayanta Chaudhuri; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; immunologi; Immunology;

    Abstract : After stimulation, B cells can undergo two types of genetic alteration in their immunoglobulin (Ig) genes: somatic hypermutation and class switch recombination (CSR), both of which are initiated by activation-induced cytidine deaminase (AID).Although class switching requires cell proliferation, the mechanism is partly unknown.
