The present invention relates to a method for producing natural killer cells using T cells, and more particularly, to a method for producing natural killer cells, which comprises culturing seed cells using CD4(+) T cells as feeder cells. The method for producing natural killer cells using T cells according to the present invention is a method capable of producing natural killer cells by selectively proliferating only natural killer cells from a small amount of seed cells while maintaining the high killing activity of the natural killer cells. The method of the present invention can produce a large amount of natural killer cells that can be frozen, and thus is useful for commercialization of cell therapeutic agents.

The present invention provides methods of preparing a population of activated T cells by co-culturing T cells with dendritic cells loaded with a plurality of tumor antigen peptides. Also provided are methods of treating cancer in an individual using the activated T cells, pharmaceutical compositions and kits for cell-based cancer immunotherapy.

Also provided are methods of treating cancer in an individual using the activated T cells, pharmaceutical compositions and kits for cell-based cancer immunotherapy.

Provided herein are methods for obtaining tumor-targeting T cells, as well as for identifying tumor-targeting TCRs.

An antigen targeting agent is provided. The antigen targeting agent binds to a mutated Kirsten rat sarcoma viral oncogene homolog (KRAS) protein having a missense mutation at position 12 when a peptide incorporating the missense mutation is presented by an HLA-A*02 molecule. The missense mutation at position 12 of the KRAS protein may be G12D, G12V or G12C. The antigen targeting agents can be used diagnostically or for immunotherapy.

Provided here in are methods of producing induced pluripotent stem cells (iPSCs) and isolated population of produced induced pluripotent stem cells (iPSCs). Also provided herein are methods of treating a subject in need thereof using the produced iPSCs or pharmaceutical compositions comprising the produced iPSCs.

The present disclosure relates, at least in part, to a closed and semi-automated system for the isolation of naive T cells, their expansion, and/or final harvest. The disclosure also relates to using those isolated cells in a large batch format for compiling stocks of stimulated CD45A+ T cells and/or using the stimulated CD45A+ T cells for therapeutic purposes.

The present invention provides CDCA1-derived epitope peptides having the ability to induce cytotoxic T cells. The present invention further provides polynucleotides encoding the peptides, antigen-presenting cells presenting the peptides, and cytotoxic T cells targeting the peptides, as well as methods of inducing the antigen-presenting cells or CTLs. The present invention also provides compositions and pharmaceutical compositions containing them as an active ingredient. Further, the present invention provides methods of treating and/or preventing cancer, and/or preventing postoperative recurrence thereof, using the peptides, polynucleotides, antigen-presenting cells, cytotoxic T cells or pharmaceutical compositions of the present invention. Methods of inducing an immune response against cancer are also provided.

Provided herein are methods for preparing and characterizing SARS-co2 antigen specific immune cell cultures and preparations and methods of using the same in adoptive immunotherapy for cancer, infections and immune disorders. Also, provided are compositions and methods for generating immune cells expressing synthetic antigen binding receptors targeting SARS-cov2 and methods of use of these cells for the treatment and prevention of COVID-19. Also provided are compositions and methods for determining immune response to SARs-cov2 in a subject, detecting SARS-cov2, measuring cytotoxicity induced by SARS-cov2, and detecting the expression and cytotoxicity of synthetic antigen binding receptors targeting SARS-cov2.

Disclosed are methods, means and compositions of matter useful for treatment of liver failure using ex vivo reprogrammed immune cells. In one embodiment, cells of the recipient (autologous) are cocultured with a regenerative cell population alone or in the presence of one or more adjuvants. Said adjuvants enhance transfer of regenerative activity from said mesenchymal stem cells to said immune cells. In one embodiment said ex vivo reprogrammed immune cells are capable of inducing death or inactivation of hepatic stellate cells. In other embodiments, said immune cells provide antifibrotic activity to induce suppression of liver cirrhosis. In other embodiments, said immune cells provide for growth factors to enhance hepatic regeneration.
