1. A method of producing a cell population comprising antigen-specific T cells, comprising the steps of:
(a) isolating peripheral blood mononuclear cells (PBMCs) from a subject;
(b) culturing said PBMCs in an antigen presenting cell (APC) induction medium comprising interleukin 4 (IL-4) and soluble CD40 ligand (sCD40L) and/or comprising granulocyte-macrophage colony-stimulating factor (GM-CSF) and interferon α (IFN-α), to produce a first population of cells, wherein the first population of cells comprises T cells;
(c) culturing the first population of cells in the presence of one or more antigens, to produce a second population of cells; and
(d) culturing the second population of cells in a T cell expansion medium comprising interleukin 7 (IL-7), interleukin 15 (IL-15), and IL-4, to produce a third population of cells;
wherein the third population of cells comprises T cells that are CD3+ and are specific for an antigen added in step (c), and
wherein all of the T cells of the third population of cells that are CD3+ and are specific of the antigen added in step (c) are derived from the T cells of the first population of cells.
