Research Abstract |
Streptococcus pneumoniae is a common pathogen of pneumonia among children and elderly persons. To identify the population of B cells, which have an important role of inducing the primary responses and memory responses against pneumococcal polysaccharides, the pneumococcal polysaccharides of serotype 3 (PPS3) were injected into the peritoneal cavity of mice. We found that expansion of polyreactive IgM+ B cell clones were detected in spleen on day 3, afterward specific IgM+ B cell clones were selected on day 7. It suggests that PPS3 is thought as TI type 1 antigens during the primary phase.
