The present invention provides KOC1-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.

The present invention provides improved and/or shortened methods for expanding TILs and producing therapeutic populations of TILs, including novel methods for expanding TIL populations in a closed system that lead to improved efficacy, improved phenotype, and increased metabolic health of the TILs in a shorter time period, while allowing for reduced microbial contamination as well as decreased costs. Such TILs find use in therapeutic treatment regimens.

The present disclosure provides a modified cell of leukemic origin comprising a downregulated CD47 pathway. Methods for using the modified cells in treating cancer alone, or in combination with CD47 blockade are also provided. Also provided are compositions comprising a modified cell of leukemic origin, pharmaceutical compositions and formulations thereof, and methods of producing the modified cells.

The present invention relates methods and compositions for preventing or treating various immune diseases including graft-versus-host disease (GVHD) using populations or compositions of immunoregulatory T cells specific for an irrelevant antigen; such cells being activated in vivo by a simultaneous, separate or sequential administration of said antigen.

Provided is a method for inducing T cells for use in a cell-based immunotherapy, comprising the steps of:

(1) providing human pluripotent stem cells bearing a T cell receptor specific for a WT1 antigen or an Epstein-Barr virus associated antigen, and
(2) inducing T cell progenitors or mature T cells from the pluripotent stem cells provided in step (1). Pluripotent stem cells may preferably be iPS cells. The human pluripotent stem cells bearing a T cell receptor specific for an antigen may be prepared by inducing iPS cells from a T cell having the desired antigen specificity or by introducing genes encoding the T cell receptor specific for the desired antigen into iPS cells. The T cells obtained by this method can be used for the treatment of various immune-related diseases such as cancers and infectious diseases.

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.

The present disclosure provides methods for re-stimulating TIL populations that lead to improved phenotype and increased metabolic health of the TILs and provides methods of assaying for TIL populations to determine suitability for more efficacious infusion after re-stimulation.

The present invention relates to a method for ex vivo generating and expanding γδ Foxp3.sup.+ regulatory T cells, and therapeutic uses thereof. The inventors performed the induction of Foxp3+ expression in ex vivo human induced tumor-antigen specific CD4+ TCRγδ unrestricted T cells and the induction of autologous CD8-mediated T-cell responses against tumor-antigen specific FOXP3 expressing CD4+ TCRγδ unrestricted T cells. The inventors developed a method to ex vivo generated and expanded antigen specific Foxp3 expressing CD3+ TCRγδ+ unrestricted T cells, committed to exclusively exert regulatory activity, whichever culture condition of stimulation is. In particular, the present invention relates to a method for generating ex vivo γδ Foxp3+ regulatory T cells having the following phenotype: CD3+ TCRγδ+ Foxp3+.

Safe, rapid, and efficient methods for producing antigen-specific T cells recognizing human papilloma virus (HPV antigens); HPV-specific T cells, and methods for treating HPV infections and HPV-related malignancies by adoptive transfer of HPV-specific T cells.
