| Outline of Final Research Achievements |
Mycoplasma pneumoniae is a common respiratory pathogen , and the participation of the excessive host immunoresponse is thought to be involved in M. pneumoniae pneumonia and the pathogenic mechanisms of the complications. Recent studies indicate that Th17 cell has been implicated in the onset of autoimmune diseases. In this report, we established an experimental pneumonia mouse model by the use of M. pneumoniae antigens and performed immunological analyses to examine the induction mechanisms. In addition, we have examined the specificity of Th 17 cell inducibility by mouse splenocytes. These analyses indicated that mRNA expression levels of IL-17A and IL-10 in the lung were increased by M. pneumoniae antigens sensitization in vivo. It was also shown that M. pneumoniae antigens induced IL-17A release from mouse splenocytes in a dose-dependent manner in vitro. These results suggest that murine Th17 response is initiated by M. pneumoniae antigen sensitization.
