  • Patent number: 12551546
    Abstract: Embodiments of the present disclosure pertain generally to head and neck squamous cell carcinomas (HNSCCs) related to human papillomavirus subtype 16 (HPV16) infections. More particularly, the present disclosure provides novel immunogenic epitopes from HPV16 E2, E6 and E7 antigens restricted by common human leukocyte antigen (HLA) alleles for the diagnosis and treatment of HNSCC. The HPV16 epitopes identified in the present disclosure can be used in combination with blockade of HPV16+ HNSCC-specific checkpoints for targeted immunotherapy.

  • Publication number: 20250057949
    Abstract: Disclosed are methods of treating or preventing cancer in a mammal, the method comprising: (a) isolating T cells from a tumor sample from the mammal, wherein the isolated T cells are one or both of exhausted and differentiated, and the isolated T cells have antigenic specificity for a tumor-specific antigen expressed by the tumor sample from the mammal, wherein the tumor-specific antigen is a tumor-specific neoantigen or an antigen with a tumor-specific driver mutation; and optionally expanding the numbers of isolated, tumor antigen-specific T cells; and (b) administering to the mammal (i) the isolated T cells of (a) and (ii) a vaccine which specifically stimulates an immune response against the tumor-specific antigen for which the isolated T cells have antigenic specificity.

  • Publication number: 20230258635
    Abstract: Disclosed are methods of obtaining a cell population enriched for T cells with a phenotype, the method comprising: (a) obtaining a bulk population of T cells from a tumor sample of a patient; (b) specifically selecting T cells with a phenotype comprising markers CD3+, CD39?, and CD69? from the bulk population; and (c) separating the cells selected in (b) from cells which lack the phenotype to obtain a cell population enriched for T cells with the phenotype. Related methods of treating or preventing cancer, methods of selecting a therapy for a cancer patient, and methods for predicting the clinical response to immunotherapy in a cancer patient are also disclosed. Isolated or purified cell population obtained according to the methods and related pharmaceutical compositions are also disclosed.

  • Publication number: 20230183802
    Abstract: Provided are methods of preparing an enriched population of T cells having antigenic specificity for a target antigen. The method may comprise isolating T cells from a blood sample of a patient; selecting the isolated T cells which have a gene expression profile; and separating the selected T cells from the unselected cells. The separated selected T cells provide an enriched population of T cells having antigenic specificity for the target antigen. Methods of isolating a TCR, preparing a population of cells that express a TCR, isolated TCRs, isolated populations of cells, pharmaceutical compositions, and methods of treating or preventing a condition in a mammal are also provided.

  • Publication number: 20100069011
    Abstract: A circuit for transmitter-receiver isolation that is useful in a monostatic (combined transmitting and receiving) antenna configuration is shown and described. In addition, methods and systems are shown for automatically adjusting the circuit in response to changes in antenna configuration, external signal reflectors, and jamming energy (e.g., self jammer energy) by adjusting the circuit to tune out these sources of jammer energy to yield an increase in RFID reader receiver sensitivity when compared to measurements of the receiver sensitivity when the jammer energy is not present.
