Abstract
The combined therapeutic effect of natural killer T (NKT) cell ligand α-galactosylceramide (α-GalCer) and IL-12 against highly metastatic B16-BL6-HM melanoma cells was investigated. In comparison with a single administration of α-GalCer or IL-12, the combined treatment of tumor-bearing mice with α-GalCer plus IL-12 caused a super-induction of serum IFN-γ levels, though α-GalCer-induced IL-4 production was rather inhibited. In parallel with the augmented IFN-γ production, the natural killing activity against YAC-1 cells and syngeneic B16- BL6-HM melanoma was greatly augmented by the combined therapy. The major effector cells responsible for natural killing activity induced by α-GalCer plus IL- 12 were enriched in both NK1.1+TCRαβ+ NKT cells and NK1.1+TCRαβ− NK cells. The preventing effect of α-GalCer or IL-12 alone against lung metastasis of B16-BL6-HM was also enhanced by the combination therapy. The antitumor activity of α-GalCer was totally abolished in NKT-deficient mice. However, IL- 12-induced antitumor activity was not eliminated in NKT-deficient mice though it was inhibited by anti-asialo GM1 Ab treatment. These findings suggested that α-GalCer synergistically act with IL-12 to activate both NKT cells and NK cells, which may play a critical role in the strong prevention of distant tumor metastasis at early stages of tumor-bearing. These data will provide a novel tool for the prevention of tumor metastasis using NKT-specific ligands α-GalCer and IL-12.
