    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgA; Intestine; Gut associated lymphoid tissue; class switch recombination; CD40; germ free;

    Sammanfattning : Production of IgA at mucosal surfaces is one of the most striking features of the mucosal immune system. Despite that IgA was first discovered in the 1950’s and secretory IgA described in gut secretions and breast milk in the mid 1960’s we still have limited information about the sites and exact requirements for IgA class switch recombination.
