Abstract

Adoptive cellular therapy remains a potentially powerful method of eradicating established tumors. T-cells have been particularly potent effector cells, as demonstrated in animal models and clinical studies, and it is apparent that the stimulation of certain subpopulations of T-cells that are reactive to tumor antigens can lead to more therapeutic T-cells. The use of gene transfer techniques has resulted in more effective and specific methods to generate these tumor-specific T-cells. Another area of tremendous interest is in the adoptive transfer of DCs manipulated to present tumor antigen to resting, naive T-cells. Gene transfer techniques may offer more optimal ways to generate therapeutic DCs. Adoptive immunotherapy may ultimately [figure: see text] have its greatest use in patients undergoing cellular rescue after ablative chemotherapy; the infusion of immunocompetent T-cells, genetically modified stem cells, or programmed DCs may offer the opportunity to direct a patient's immune response to eliminate residual microscopic disease.
