  • Publication number: 20230071538
    Abstract: Cytotoxic T cells derived from human T cell-derived iPS cells may avoid an NK cell missing-self response and may be used for allogeneic administration while maintaining a strong antitumor effect of antigen-specific CTLs. A method may produce a cytotoxic T cell derived from a human T cell-derived iPS cell expressing HLA class I of HLA-restricted class I of an antigen epitope of a CTL and HLA-E. Such a method may include: knocking out all HLA class I of the human T cell-derived iPS cell; introducing a gene of the HLA-restricted HLA class I of the antigen epitope of the CTL and a gene of the HLA-E into the T-iPS cell in which all HLA class I have been knocked out; and redifferentiating the genetically introduced T-iPS cell into a CD8 single-positive T cell.
