| Outline of Final Research Achievements |
The purpose of this study was to elucidate the role of natural killer T (NKT) cells in chronic inflammation elicited by dyslipidemia, which result in atherosclerosis. Splenocytes from apolipoprotein-E deficient mice, including mononuclear phagocytes and NKT cells, were cultured with α-Galactosylceramide (α-GalCer), which specifically activates NKT cells, and significantly reduced in the production of inflammatory cytokines compared to those from wild-type mice, suggesting NKT cell anergy. Splenocytes cultured with Th1 or Th2 cytokines were stimulated with α-GalCer, but did not differ in the production of inflammatory cytokines between apolipoprotein-E deficient mice and wild-type mice. Thus, we could not elucidate the significant role of NKT cells in chronic inflammation in the present study.
