Abstract: There is controversy on the role of IgM memory and switched memory B lymphocytes in the Ab response to T cell-independent and T cell-dependent Ags. We transplanted SCID/SCID mice with human B lymphocyte subsets and immunized them with heat-inactivated Streptococcus pneumoniae or with a pneumococcal vaccine. Inactivated S. pneumoniae and soluble pneumococcal capsular polysaccharides elicited an IgM anti-polysaccharide and anti-protein Ab response from IgM memory B lymphocytes and an IgG anti-polysaccharide and anti-protein response from switched memory B lymphocytes. In addition to the IgM Ab response, IgM memory B cells elicited an IgG anti-polysaccharide and anti-protein Ab response after immunization with inactivated S. pneumoniae or soluble pneumococcal capsular polysaccharides. In conclusion, our findings provide evidence for a versatile role of IgM memory B cells in T-independent and T-dependent immune responses.
