  • Publication number: 20220308061
    Abstract: The disclosure provides methods and materials useful for obtaining novel TCR gene sequences that are useful in tumor-specific T cell receptor (TCR) gene transfer. Embodiments of the invention also include methods of crosslinking and permeabilizing mammalian cells that can, for example, be used in methods for obtaining novel TCR gene sequences. The disclosure further provides methods and materials useful for obtaining novel TCR gene sequences. Tumor-specific T cell receptor gene transfer enables specific and potent immune targeting of tumor and viral antigens, and for this reason is technology of significant interest to medical personnel.

  • Publication number: 20220244263
    Abstract: The current disclosure provides for methods of identifying and treating small cell neuroendocrine (SCN) tumors and small-round-blue cell tumor (SRBCT). Aspects of the disclosure relate to a method comprising measuring the level of expression of one or more biomarkers from Tables 1-3 in a biological sample from a cancer patient. Further aspects relate to a method for treating small cell neuroendocrine (SCN) cancer or small-round-blue cell tumor (SRBCT) in a patient comprising administering a cancer treatment to the patient, wherein the cancer treatment is a treatment selected from Table 4A, 4B, or combinations of treatments from Table 4A and/or 4B.

  • Publication number: 20210324035
    Abstract: Tumor-specific T cell receptor (TCR) gene transfer enables specific and potent immune targeting of tumor antigens. The canonical cancer-testis antigen, NY-ESO-1, is not expressed in normal tissues but is aberrantly expressed across a broad array of cancer types. It has also been targeted with A2-restricted TCR gene therapy without adverse events or notable side effects. To enable the targeting of NY-ESO-1 in a broader array of HLA haplotypes, we isolated TCRs specific for NY-ESO-1 epitopes presented by four MHC molecules: HLA-A2, -B07, -B18, and -C03. Using these TCRs, we have developed an approach to extend TCR gene therapies targeting NY-ESO-1 to patient populations beyond those expressing HLA-A2.

  • Publication number: 20210236548
    Abstract: Provided herein are methods of treating neuroendocrine prostate cancer (NEPC) with immune cells comprising a CEA-CAM5 chimeric antigen receptor (CAR). Also provided are methods of reducing or eliminating NEPC cancer cells with immune cells comprising a CEACAM5 CAR. Also provided are methods of treating a cancer with a molecular signature that is similar to a molecular signature of NEPC (e.g., small cell lung cancer (SCLC), small cell carcinoma of the pancreas (SCCP), or small cell prostate cancer).

  • Patent number: 10900956
    Abstract: In certain embodiments methods of identifying T cell receptors that respond to specific target cell antigens are provided, where the methods comprise providing a substrate bearing a plurality of target cells (e.g., mammalian cells); contacting the target cells on the substrate with CD8+ T cells; and using label-free optical imaging to identify an increase in mass of a T-cell and/or a decrease in mass of a target cell, where an increase in mass of a T cell and/or a decrease in mass of a target cell is an indicator that said T cell bears a T cell receptor activated by antigens presented on said target cell.
