title: Adoptive T-cell transfer in cancer immunotherapy.
abstract: Adoptive T-cell therapy has definite clinical benefit in relapsed leukaemia after allogeneic transplant and in Epstein-Barr virus-associated post-transplant lymphoproliferative disease. However, the majority of tumour targets are weakly immunogenic self-antigens and success has been limited in part by inadequate persistence and expansion of transferred T cells and by tumour-evasion strategies. Adoptive immunotherapy presents the opportunity to activate, expand and genetically modify T cells outside the tolerising environment of the host and a number of strategies to optimize the cellular product, including gene modification and modulation of the host environment, in particular by lymphodepletion, have been developed.
