  • Patent number: 10813950
    Abstract: The present invention provides an agent for an immunocyte therapy, comprising an NKT cell obtained by differentiating in vitro a cell having the ?-chain region of the T cell receptor gene rearranged to uniform V?-J? in an NKT cell receptor-specific way, wherein an administration subject is an allogenic individual having MHC gene loci including at least one locus having a genotype different from that of the NKT cell. In addition, the present invention provides a bank of a human cell or an NKT cell derived from said cell, wherein the ?-chain region of a T cell receptor (TCR) gene has been rearranged to uniform V?-J?. The agent and cell bank of the present invention are useful for the prophylaxis and/or treatment of cancer, infection, an allergic disease or an autoimmune disease.
