  • 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.

  • Publication number: 20110231944
    Abstract: Provided are a B cell-derived iPS cell generated using a convenient technique, a technology for providing a human antibody at low cost using the iPS cell, an immunologically humanized mouse prepared using cells differentiated from the iPS cell, and the like. Also provided are a cloned cell obtained by contacting a B cell with nuclear reprogramming factors excluding C/EBP? and Pax5 expression inhibiting substances, particularly nucleic acids that encode Oct3/4, Sox2, Klf4 and c-Myc, wherein the cloned cell has an immunoglobulin gene rearranged therein and possesses pluripotency and replication competence (B-iPS cell).

  • Publication number: 20110020932
    Abstract: The present invention provides a production method of a functional differentiated cell having a post-rearrangement genotype of a particular antigen receptor gene, which includes culturing a stem cell having the genotype in a medium to give the differentiated cell derived from the stem cell. As the stem cell having the genotype, a stem cell (e.g., ES cell) established by transplantation of the nucleus of a cell having the genotype is preferable. As the differentiated cell, NKT cell is preferable.
