Research Abstract

The role of indoleamine 2,3-dioxygenase (Ido) in the L-tryptophan (Trp)-kynurenine (Kyn) pathway after lung metastasis model by injecting B16F10 cells was investigated. We used mice treated with 1-methyl-D or L-tryptophan (D or L-1MT), an inhibitor of Ido1 or Ido2, to study the importance of Trp-Kyn pathway metabolites. On day 7 after B16F10 cells, we administrated each NKT activated ligands (alpha-GalCer and 7DW8-5). The levels of serum IFN-g and Ido activity in mice 6 hours after alpha-GalCer injection were higher than those in non-treated mice. Furthermore, the levels of Ido1 and Ido2 mRNA and protein expression in the lung and serum Trp metabolites from mice treated with alpha-GalCer were significantly higher than those from non-treated mice. Moreover, the anti-tumor effect in the lung from mice treated with alpha-GalCer and D- or L-1MT combined administration was markedly improved compared to that in mice treated with -GalCer single administration.
