Abstract :
IgA has traditionally been regarded a non-inflammatory antibody. This might indeed be true for secretory IgA (SIgA), which exerts its function at mucosal surfaces where commensal microorganisms and dietary antigens prevail. Serum IgA, however, potently triggers (pro)-inflammatory activity upon binding to the myeloid IgA receptor, FcαRI. Here, new insights in the roles of IgA and FcαRI are addressed and a model integrating the various functions of IgA in immunity is discussed.
