This document provides methods and materials for treating cancer. For example, methods and materials for identifying antigens and combinations of antigens that can be used to treat cancer as well as combinations of antigens having the ability to reduce established tumors (e.g., gliomas) within a mammal (e.g., a human) are provided. In general, one aspect of this document features a composition comprising, or consisting essentially of, nucleic acid encoding HIF-2a, SOX-10, C-MYC, and TYRP-1, wherein the composition comprises less than 100 separate nucleic acid molecules.

The present invention relates to uses of and methods of using activators of Nrf2 to enhance natural killer (NK) cell and/or T cell activity and/or survival, particularly in response to stress. The NK cells and/or T cells can be utilised in the treatment of cancer via enhanced cell therapy.

Provided herein are methods and compositions for the treatment of melanoma using anti-tumor immune cells treated with a PTD-MYC fusion protein (e.g., an HIV TAT-MYC fusion protein).

CAR cells targeting tumor necrosis therapy relevant antigens are described as a new method of cancer treatment. It is proposed that TNT CAR cells are safe and effective in patients and can be used to treat human tumors and cancer.

The disclosure relates to methods, cells, and compositions for preparing cell populations and compositions for adoptive cell therapy. In particular, provided herein are methods for expansion and proliferation of primary immune cells including T cell populations.

Described herein is a recombinant Eomes protein that restores the cytotoxic activity of exhausted immune cells. This protein comprises, a nuclear localization sequence (NLS), the transcription factor associated domain of Eomesodermin (Eomes), and a protein-transduction domain (PTD). The NLS-Eomes-PTD polypeptide spontaneously internalizes into NK cells and travels to the nucleus to control the transcription of its down-stream signaling pathways. Introduction of the NLS-Eomes-PTD polypeptide into ExNK cells (i) decreases the expression of an inhibitory antigen on ExNK cells; (ii) increases cytolytic activity: (iii) enhances cytokine secretion; (iv) improves proliferation; and (v) inhibits tumor growth.

A nucleic acid construct and an immune cell, which harbor nucleic acids encoding a CAR and nucleic acids encoding at least one anti-inflammatory or immunosuppressant protein and methods of using the same in treatment or amelioration of inflammation or immune-mediated autoimmunity are described.

The neuroblastoma immunopeptidome is enriched with peptides derived from proteins essential for tumorigenesis including the unmutated peptide QYNPIRTTF (SEQ ID NO: 1) discovered on HLA-A*24:02 which is derived from the neuroblastoma dependency gene and master transcriptional regulator PHOX2B. To target QYNPIRTTF, peptide-centric chimeric antigen receptors (PC-CARs) were developed via a counter panning strategy using predicted potentially cross-reactive peptides. Informed by computational modeling, PHOX2B peptide centric CARs were demonstrated to also recognize QYNPIRTTF (SEQ ID NO: 1) presented by HLA-A*23:01 and the highly divergent HLA-B*14:02. Potent and specific killing of neuroblastoma cells expressing these HEAs in vitro was shown along with complete tumor regression in mice.

Provided herein are methods and compositions for the treatment of melanoma using anti-tumor immune cells treated with a PTD-MYC fusion protein (e.g., an HIV TAT-MYC fusion protein).

Compositions for T cell-based immunotherapy of HIV, HIV-associated malignancies, HIV-associated viral infections, or other HIV-related complications. Modified T cells that are resistant to invasion or infection with HIV, such as T-cells modified to decrease or eliminate expression of mannosyl-oligosacharide glucosidase enzyme (MOGS). Methods for producing such compositions by expanding HIV-specific T cells from different sources to recognize multiple HIV antigens.
