  • Publication number: 20240024479
    Abstract: Modified natural killer (NK) or T cells expressing hematopoietic growth factor receptors are provided. In some aspects, the modified NK cells or T cells express a thrombopoietin receptor, an erythropoietin receptor, or a chimeric polypeptide including an extracellular domain of a thrombopoietin receptor, a transmembrane domain, and an intracellular domain including an interleukin-2 receptor beta intracellular signaling domain. Methods of treating a subject with cancer are also provided, including administering the modified NK cells or T cells to the subject in combination with a thrombopoietin receptor agonist or erythropoietin receptor agonist, and in some example, interleukin-2, particularly reduced or low-dose amounts of IL-2.

  • Patent number: 11779603
    Abstract: Disclosed herein are T cell receptors (TCRs) capable of binding an antigen expressed by renal cell carcinoma cells. In some examples, the TCRs include an ? chain (such as SEQ ID NO: 2) and a ? chain (such as SEQ ID NO: 3). Also disclosed herein are vectors including nucleic acids encoding the disclosed TCR ? and/or ? chains. Further disclosed are modified T cells expressing the TCRs. In some examples, the modified T cells are prepared by transducing T cells with a vector including nucleic acids encoding the TCR ? chain and the TCR ? chain. In some embodiments, methods include treating a subject with RCC, by obtaining a population of T cells, transducing the population of T cells with a vector including a nucleic acids encoding the TCR ? chain and the TCR ? chain, and administering a composition comprising the modified T cells to the subject.

  • Publication number: 20220228117
    Abstract: Disclosed herein are method of producing NK cells that include one or more heterologous nucleic acids. The methods include culturing a population of isolated NK cells in the presence of one or more cytokines to produce a population of activated NK cells. The population of activated NK cells are transduced with a viral vector comprising the one or more heterologous nucleic acids, for example by contacting the activated NK cells with viral particles including the viral vector. The resulting transduced NK cells are then cultured in the presence of one or more cytokines, and optionally in the presence of irradiated feeder cells, to produce a population of expanded transduced NK cells. Also disclosed are methods of treating a subject with a disorder (such as a tumor or hyperproliferative disorder) by administering to the subject NK cells produced by the methods described herein.
