Zusammenfassung
Introduction: We have shown recently that basophils play an important role in enhancing secondary humoral memory immune responses to intact pneumococcal protein antigen, thereby markedly improving survival in a mouse model of pneumococcal sepsis. We here investigated the effect of expanded basophil pool sizes on immunization efficacies against S. pneumoniae in mice. Methods: Mice underwent primary and secondary immunization with the pneumococcal surface protein A (PspA). Basophil pool sizes were expanded immediately prior to secondary immunization by treatment with IL-3 or IL-3 complexed with anti-IL-3 antibody.…
