1. A method of producing a cultured polyclonal population of cytotoxic T-lymphocytes (CTLs) that recognize at least one epitope from each of at least two different tumor antigens, said population comprising CD4+ T-lymphocytes and CD8+ T-lymphocytes, comprising the steps of:
ia) stimulating DCs or PBMCs with at least two libraries of peptides that each represent at least one epitope from each of at least two different tumor antigens to generate antigen presenting cells (APCs) and stimulating T cells with the APCs to generate antigen-specific T lymphocytes; or
ib) stimulating PBMCs with at least two libraries of peptides that each represent at least one epitope from each of at least two different tumor antigens to generate antigen-specific T-lymphocytes; and
ii) culturing the antigen-specific T-lymphocytes in the presence of IL-7 and IL-15 to generate a population of CTLs.
