  • Patent number: 11744860
    Abstract: The present invention relates to a method for producing en NKT cell ligand-pulsed human CD14 positive cell that activates NKT cells and strongly induces proliferation, IFN-? production, and/or cytotoxic activity of NKT cells. More specifically, the method is characterized in that the isolated CD14 positive cell is cultured in a medium containing an NKT cell ligand and GM-CSF and substantially free of IL-4. In addition, the present invention relates to a method for producing an NKT cell ligand-pulsed human CD14 positive cell line and, specifically, the method is characterized in that the isolated CD14 positive cell is cultured in a medium containing an NKT cell ligand and substantially free of GM-CSF and IL-4. The present invention also relates to a cell preparation containing an NKT cell ligand-pulsed human CD14 positive cell or an NKT cell ligand-pulsed human CD14 positive cell line and pharmaceutical use thereof.
