摘要： Provided herein is a system for inducible expression of a chimeric antigen receptor in cells, such as mammalian cells. The system comprises: a) a first nucleic acid comprising a first promoter inducible by a drug, wherein the first nucleic acid is operably linked to a first polynucleotide that encodes a chimeric antigen receptor, which comprises a ligand binding domain that is specific for a ligand selected from the group consisting of a tumor specific molecule, a viral specific molecule, and any other selected molecule expressed on a target cell population, wherein the ligand elicits recognition, modulation, inhibition, and/or elimination by a lymphocyte, a second polynucleotide, which encodes a spacer or an optimized polypeptide spacer, a third polynucleotide, which encodes a transmembrane domain and a fourth polynucleotide, which encodes an intracellular signaling domain and b) a second nucleic acid comprising a second promoter that is operably linked to a nucleic acid encoding a transcriptional activator for the first promoter inducible by drug, wherein the system is inducible by an amount of the drug that is less than a comparable system utilizing a wild type HEA3 chimeric transcription factor, or the system has an enhanced transcriptional expression at a given concentration of the drug compared to a wild type HEA3. Methods of making such cells and methods of treatment using these cells are also provided.

摘要： 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.

摘要： The present invention provides nucleic acids, vectors, host cells, methods and compositions to confer and/or augment immune responses mediated by cellular immunotherapy, such as by adoptively transferring CD8+ central memory T cells or combinations of central memory T cells with CD4+ T cells that are genetically modified to express a chimeric receptor under the control of an inducible promoter. In some alternatives the genetically modified host cell comprises a nucleic acid comprising a polynucleotide coding for a chimeric antigen receptor comprising a ligand binding domain, a polynucleotide comprising a spacer region, a polynucleotide comprising a transmembrane domain, and a polynucleotide comprising an intracellular signaling domain under the control of a drug inducible promoter. Controlling the expression of the chimeric receptor provides for the ability to turn expression on and off depending on the status of the patient. Pharmaceutical formulations produced by the method, and methods of using the same, are also described.
