    Abstract: A method of expanding double negative T cells in culture is described. The method comprises (a) providing a starting sample comprising DN T cells or precursors thereof; (b) substantially depleting CD8+ and CD4+ T cells from the starting sample; (c) culturing the sample from step (b) with an immobilized T cell mitogen in a culture medium comprising an agent that can stimulate DN T cell growth (d) washing the cells obtained in step (c) and resuspending in a culture medium comprising the agent without the T cell mitogen; and (e) washing the cells obtained in step (d) and resuspending in a culture medium comprising the agent and a soluble T cell mitogen. The DN T cells obtained by the method are useful in a variety of applications including the treatment of cancer, infectious diseases, graft versus host disease and autoimmune disease.
