The present invention provides methods of expanding T cells from a non-haematopoietic tissue source. Further provided are compositions of expanded T cells and methods of using the expanded T cells (e.g., apart of an adoptive T cell therapy).

Embodiments of the disclosure concern methods and compositions for immunotherapy for human papillomavirus infection and diseases associated therewith. In specific embodiments, methods concern production of immune cells that target one or more antigens of HPV16 and/or HPV18, including methods with stimulation steps that employ IL-7 and IL-15, but not IL-6 and/or IL-12. Other specific embodiments utilize stimulations in the presence of certain cells, such as costimulatory cells and certain antigen presenting cells.

The present invention relates to cell culture in bioreactors, such as flexible cellbag bioreactors. More specifically the present invention relates to methods for simplifying the production of clinically relevant cell products for use in cell therapy.

Disclosed are methods of obtaining a cell population enriched for T cells having antigenic specificity for a cancer-specific mutation using in vitro stimulation of memory T cells. Also disclosed are related methods of isolating a T cell receptor (TCR), populations of cells, TCRs or antigen-binding portions thereof, pharmaceutical compositions, and methods of treating or preventing cancer.

Provided by the disclosure are compositions and methods for modulating differentiation of regulatory T cells. In some embodiments, methods include selectively decreasing IL-23R activity and/or IL-23R expression without significantly decreasing IL-12RP activity and/or IL-12RP expression.

The present invention provides isolated cell compositions for the treatment of cancer, including hematological and solid tumors, comprising a selected, fixed ratio of multiple ex vivo activated lymphocytic cell subsets, including specific immune effector cells directed to specific tumor associated antigens (TAAs), viral associated tumor antigens (VATA), glycolipids, or a combination thereof. By selecting specific fixed ratios of different lymphocytic cell subsets, an immune response which is comprehensive and broad pin biological and immune effector function is provided, enhancing the ability of the administered cells to mount an effective and robust immune response.

A method for producing natural killer cells is disclosed. The method comprises isolating peripheral blood mononuclear cells (PBMCs) from a blood sample; isolating at least one of CD56+ cells and/or CD3/CD56+ cells from the PBMCs; and co-culturing the at least one of CD56+ cells and/or CD3/CD56+ cells with a combination of feeder cells in the presence of a cytokine. A composition for treating cancer is also disclosed. The composition comprises the CD56+ natural killer cells produced by the disclosed method and a cytokine.

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 invention relates to a cancer-specific tumor antigen neoepitope represented by any one of SEQ ID NOs: 1 to 184, an antigen-presenting cell loaded with the neoepitope, and a method for activating T cells for cancer treatment using the antigen-presenting cell. An antigen-presenting cell, that is, a dendritic cell, loaded with a cancer-specific tumor antigen epitope provided in the present invention enables rapid and effective induction of differentiation and proliferation of cancer antigen-specific T cells, preferably memory T cells, and the memory T cells thus activated can treat a cancerous or neoplastic condition or prevent recurrence, progression, or metastasis of cancer while avoiding the defense mechanism of cancer cells.

Herein is reported a method for co-cultivating one or more B-cells comprising the step of incubating the one or more B-cells with EL4-B5 cells, whereby the EL4-B5 cells have been obtained/are from a cultivation of EL4-B5 cells that has a cell density of from 600,000 cells/ml up to 1,500,000 cells/ml.
