title: [B7 costimulation molecules improve induction of tumor specific cytotoxic T-cells against MART-1(27-35)].
abstract: The expression of B7-1/2 molecules in addition to TAA in APC significantly improves the generation of specific CTL in vitro. Moreover, human fibroblasts, usually devoid of APC capacity, can be engineered into effective APC upon infection with recVV encoding costimulatory molecules together with specific epitopes. The generation of artificial APC by infection of non professional APC with appropriately engineered recVV is a new concept that may be useful in the implementation of immunotherapy strategies.
