Described herein are methods for preparing T cells, including isolating CD8+ T cells from a blood sample obtained from a patient or a donor, culturing the isolated CD8+ T cells in the presence of at least one cytokine, contacting the cultured CD8+ T cells with a multimer containing a target peptide in a complex with an MHC molecule and with at least one binding agent that binds to a T cell surface molecule, in which the multimer is labelled with a first detectable agent and the binding agent is labelled with a second detectable agent, sorting the contacted CD8+ T cells to collect the sorted CD8+ T cells that are detected positive for the first and the second detectable agents, and expanding the collected CD8+ T cells.

Methods for manufacturing T cells by direct sorting and compositions thereof

The present disclosure provides for methods of improving the efficacy of T cells. In an aspect, the disclosure further provides for methods of enhancing the persistence of T cells for adoptive cell transfer or therapy (ACT). Cytokine sensitivity assays (CSA) and associated methodology capable of predicting the persistence of adoptively infused T Cells are further provided for by way of the instant disclosure. The disclosure also provides for methods of treating cancer in a subject in need thereof as well as T cells populations produced by methods described herein.

Method of enhancing persistence of adoptively infused T cells

The disclosure relates to methods of manufacturing T cells for adoptive immunotherapy. The disclosure further provides for methods of genetically transducing T cells, methods of using T cells, and T cell populations thereof. In an aspect, the disclosure provides for methods of thawing frozen peripheral blood mononuclear cells (PBMC), resting the thawed PBMC, activating the T cell in the cultured PBMC with an anti-CD3 antibody and an anti-CD28 antibody immobilized on a solid phase, transducing the activated T cell with a viral vector, expanding the transduced T cell, and obtaining expanded T cells.
