| Outline of Final Research Achievements |
This study revealed that Zizimin2, of which expression level is decreased with aging, increases splenic marginal zone B cell and peritoneal cavity B1b cell number in mice. In addition, the expression level in those cells from aged mice was significantly lower than that from young mice. Importantly, we also demonstrated some regulatory elements for the expression upstream from murine Zizimin2 gene transcription start site. It will be required in the near future if activation of Zizimin2 gene rejuvenates the immunological function of elderly people or mice.
