    摘要: Provided are methods of administering peptides containing portions of or corresponding to an agent to be administered, such as a cell or molecule expressed by such cell such as a recombinant protein such as a chimeric receptor. In some embodiments, the administration is in conjunction with treatment methods employing the agent, e.g., cell or chimeric receptor, such as adoptive cell therapy methods. The chimeric receptor can be a chimeric antigen receptor (CAR). The peptides contain an epitope of the recombinant receptor and, in some embodiments, are capable of downregulating or reducing immune responses against the chimeric receptor, such as CAR. Also provided are such peptides and compositions that can induce tolerance to an agent such as a chimeric receptor, such as a CAR.

    摘要: Provided are methods for preparing T cells for cell therapy, compositions produced by the methods, and methods of administering the cells to subjects. In particular, the disclosure relates to preparation of engineered T cells, such as those expressing genetically engineered receptors, such as genetically engineered antigen receptors such as engineered (recombinant) TCRs and chimeric antigen receptors (CARs), or other recombinant chimeric receptors. Features of the methods include producing a more consistent and/or predictable T cell product and/or lower toxicity compared with other methods. The provided methods include incubating cells under stimulating conditions to induce expansion or proliferation of naive-like T cells compared to non-naive like T cells in the stimulated composition, which in turn can result in preferential transduction of cells derived from the naive-like T cells. Features of the methods can also include reduction in costs, numbers of steps, and resource expenditure compared with other methods.

    摘要: The present disclosure relates in some aspects to methods, cells, and compositions for preparing cells and compositions for genetic engineering and cell therapy. Provided in some embodiments are streamlined cell preparation methods, e.g., for isolation, processing, incubation, and genetic engineering of cells and populations of cells. Also provided are cells and compositions produced by the methods and methods of their use. The cells can include immune cells, such as T cells, and generally include a plurality of isolated T cell populations or types. In some aspects, the methods are capable of preparing of a plurality of different cell populations for adoptive therapy using fewer steps and/or resources and/or reduced handling compared with other methods.
