Adoptive T-cell therapy, in which T cells are isolated or engineered to be specific for molecules expressed on diseased cells and administered to patients, has shown efficacy in infections and malignancy. Clinical applications of T-cell therapy have been facilitated by identification of target antigens expressed by viruses and tumors, improvement in strategies for the isolation and genetic engineering of antigen-specific T cells with intrinsic qualities that enable their persistence in vivo, and recognition that transferring T cells into a lymphopenic environment improves the efficiency of cell transfer and treatment efficacy. Insights into the obstacles to routinely achieving an effective antitumor response either by T-cell therapy or vaccination have been derived from careful analysis of clinical trials, and further development of immune cell therapy combined with interventions that target specific regulatory or inhibitory pathways that are present in tumor microenvironments and impede effective immunity represent promising areas for future applications.
