A method of treating a patient who has glioblastoma and/or gastric cancer includes administering to said patient a composition containing a population of activated T cells that selectively recognize cells in the patient that aberrantly express a peptide. A pharmaceutical composition contains activated T cells that selectively recognize cells in a patient that aberrantly express a peptide, and a pharmaceutically acceptable carrier, in which the T cells bind to the peptide in a complex with an WIC class I molecule, and the composition is for treating the patient who has glioblastoma and/or gastric cancer. A method of treating a patient who has glioblastoma and/or gastric cancer includes administering to said patient a composition comprising a peptide in the form of a pharmaceutically acceptable salt, thereby inducing a T-cell response to the glioblastoma and/or gastric cancer.

The present invention pertains to antigen recognizing constructs against COL6A3 antigens. The invention in particular provides novel T cell receptor (TCR) based molecules which are selective and specific for the tumor expressed antigen COL6A3. The TCR of the invention, and COL6A3 antigen binding fragments derived therefrom, are of use for the diagnosis, treatment and prevention of COL6A3 expressing cancerous diseases. Further provided are nucleic acids encoding the antigen recognizing constructs of the invention, vectors comprising these nucleic acids, recombinant cells expressing the antigen recognizing constructs and pharmaceutical compositions comprising the compounds of the invention.

Disclosed are yeast-based immunotherapeutic compositions comprising Brachyury antigens, and methods for the prevention and/or treatment of cancers characterized by the expression or overexpression of Brachyury.

The invention relates to a chimeric antigen-receptor polypeptide heterodimer comprising two polypeptides, wherein the first contains an extracellular part of the major histocompatibility complex I alpha chain and the second contains a 32-microglobulin domain, or the first contains an extracellular part of the major histocompatibility complex II alpha chain and the second contains a major histocompatibility complex II beta chain. One of the polypeptides further contains a transmembrane domain, a hinge region and an intracellular domain of the T cell receptor alpha chain and the other one contains a transmembrane domain, a hinge region and an intracellular domain of the T cell receptor beta chain, and additionally an antigen-peptide covalently linked to said extracellular MHC domain. The invention further relates to a method for the identification of a TCR recognizable peptide sequence making use of the heterodimer of the invention.

Chemically induced dimerizers (AbCIDs) have emerged as one of the most powerful tools to artificially regulate signaling pathways in cells; however, no facile method to identify or design these systems currently exists. The present invention provides a methodology to rapidly generate antibody-based chemically induced dimerizers (AbCIDs) from known small-molecule-protein complexes by selecting for synthetic antibodies that recognize the chemical epitope created by the bound small molecule. Success of this strategy is demonstrated by generating ten chemically-inducible antibodies against the BCL-xL/ABT-737 complex. Three of the antibodies are highly selective for the BCL-xL/ABT-737 complex over BCL-xL alone. Two exemplary important cellular applications of AbCIDs are demonstrated by applying them intracellularly to induce CRISPRa-mediated gene expression and extracellularly to regulate CAR T-cell activation with the small molecule, ABT-737. ABT-737 is not toxic at the concentrations used to activate AbCIDs in cells. AbCIDs provided by this invention are new and orthogonal AbCIDs, expanding the limited toolbox of available CIDs.

The present invention relates to methods for producing immuno-stimulatory antigen-presenting cells. The present invention further relates to the use of such cells for treating patients suffering from hyper-proliferative disease such as cancer.

Disclosed are methods of making a genetically modified immune cell for modifying a tumor microenvironment (TME) and methods of modifying a tumor microenvironment (TME). In some embodiments, the method can include delivering a first vector to an immune cell, wherein the first vector comprises a nucleic acid encoding a protein that induces T-cell proliferation, promotes persistence and activation of endogenous or adoptively transferred NK or T cells and/or induces production of an interleukin, an interferon, a PD-1 checkpoint binding protein, HMGB1, MyD88, a cytokine or a chemokine. Methods of modulating the suppression of the immune response in a tumor microenvironment, minimizing the proliferation of tumor and suppressive cells, and increasing the efficiency of an anti-cancer therapy, anti-infection therapy, antibacterial therapy, anti-viral therapy, or anti-tumoral therapy are also provided.

The present disclosure provides a chimeric antigen receptor (CAR) specific for albumin. The present disclosure also provides compositions comprising the CAR, polynucleotides encoding the CAR, vectors comprising a polynucleotide encoding the CAR, engineered cells comprising the CAR, and method using the same.

There is described herein a method for improving the anti-cancer properties of T-cells, the method comprising: providing a population of T-cells; and culturing the T-cells in an environment that activates the GCN2 pathway.
