Gene transfer vectors expressing herpes simplex thymidine kinase (HSVtk), in addition to direct killing of tumor cells, often have an associated local 'bystander effect' mediated by metabolic coupling of tumor cells. A systemic antitumor effect mediated by the immune system, termed the distant bystander effect, has also been reported. We have observed the development of cytotoxic T-lymphocyte (CTL) popu- lations and long-lasting antitumor immunity following treatment of subcutaneous tumors with an adenoviral vector expressing HSVtk (AV.TK) and ganciclovir (GCV) in rat glioma model. This vaccination effect seen with AV.TK/GCV treatment of subcutaneous tumor could even abrogate or retard growth of previously established secondary intracranial tumors. [ABSTRACT FROM AUTHOR] |
