چکیده انگلیسی
Assessment of immune responses induced by mucosal vaccines is to a large extent based on measurement of IgA levels in mucosal secretions and detection of short-lived effector IgA-secreting cells circulating in peripheral blood. Since these immunological parameters poorly reflect long-term IgA-mediated responses, we sought to investigate novel approaches that would enable detection of vaccine specific IgA memory B cells. We demonstrate that stimulation of human peripheral blood mononuclear cells in vitro with immunostimulatory DNA in combination with B cell-activating factor (BAFF) and IL-15 promotes differentiation of IgA memory B cells to IgA-secreting cells. By using the inactivated oral cholera vaccine Dukoral® we demonstrate that vaccine specific IgA memory B cells are induced by oral immunization and are circulating for at least 9 months after vaccination. We also show that stimulated IgA memory B cells do not secrete IgA unless they reencounter the specific antigen.
