Abstract: The present invention aims to provide a CAR that contains a single-chain antibody capable of specifically binding to GPC3 localized in the cell membrane and is useful for cancer immunotherapy using a CAR-T cell; and an immunocompetent cell expressing such a CAR. A gene encoding a CAR containing: a single-chain antibody that contains specific heavy-chain CDR1 to CDR3 and specific light-chain CDR1 to CDR3, as defined in claim 1, and specifically binds to a human-derived GPC3 polypeptide; a transmembrane region fused to a carboxyl terminus of the single-chain antibody; and an immunocompetent cell activation signaling transduction region fused to a carboxyl terminus of the transmembrane region is produced, and the gene is introduced into an immunocompetent cell. Thereby, a CAR-expressing immunocompetent cell having excellent cytotoxic activity on cancer cells and interferon gamma (IFN-γ) producibility can be produced.

Abstract: An object of the present invention is to provide: an anti-GPC3 antibody that recognizes an epitope different from that for existing antibodies (e.g., GC33 and GC199) and can specifically bind, even in the form of single chain antibody, to GPC3 localized on a cell membrane; CAR comprising the anti-GPC3 single chain antibody; an immunocompetent cell expressing the CAR; a gene of the anti-GPC3 antibody or a gene of the CAR; a vector comprising the anti-GPC3 antibody gene or the CAR gene; a host cell in which the vector has been introduced; a method for specifically detecting GPC3; and a kit for specifically detecting GPC3. An antibody comprising particular heavy chain CDR1 to CDR3 and particular light chain CDR1 to CDR3 defined in claim 1, and specifically binding to a human-derived GPC3 polypeptide specifically binds to GPC3 localized on a cell membrane. CAR-immunocompetent cells prepared on the basis of CAR comprising such single chain antibody are useful for cancer immunotherapy.

Abstract: A genetically modified cell that can be mass-produced efficiently. The genetically modified cell production system includes a cell-processing isolator for seeding a T cell in a well plate (culture vessel) a cell culture incubator (cell storage) for holding the culture vessel in which the T cell has been seeded and culturing the T cell a virus-processing isolator (nucleic acid preparation isolator) for providing, to the well plate, a virus having a nucleic acid containing a gene to be introduced into a cell a virus storage (nucleic acid storage) for holding the well plate from the virus-processing isolator and a virus infection isolator (nucleic acid introduction isolator) for introducing the nucleic acid into the T cell by infecting the T cell with the virus.

Abstract: The present invention provides immune cells (such as CAR-T cells) having higher antitumor activity than immune cells (such as CAR-T cells) expressing a CAR alone (not expressing cytokines and/or chemokines). A T cell provided in one aspect of the present invention expresses (1) a chimeric antigen receptor (CAR), (2) at least one selected from the group consisting of interleukin-15 (IL-15), interleukin-18 (IL-18), interleukin-21 (IL-21), and interleukin-27 (IL-27), and (3) CC chemokine ligand 19 (CCL19).

Abstract: An object of the present invention is to provide an immunocompetent cell targeting mesothelin. An immunocompetent cell that expresses a cell surface molecule specifically recognizing human mesothelin, interleukin 7 (IL-7), and chemokine (C-C motif) ligand 19 (CCL19) is produced. It is preferred that: the cell surface molecule specifically recognizing human mesothelin should be chimeric antigen receptor (CAR) having single chain antibody, a transmembrane region, and a signaling region that induces the activation of the immunocompetent cell; and the heavy chain variable region and the light chain variable region should be connected via a peptide linker consisting of a 2- to 30-amino acid sequence.
