1. ABSTRACT

Establishment of a system that allows selective gene transfer to a tumor is expected to enable targeted therapy. Using a combination of fiber-modified adenovirus and antibody to a cell surface antigen, we have explored methods to enhance the selectivity of gene transfer. In addition, we aimed to establish a systematic screening method to search for antibody and cell surface target candidates for providing highly selective gene transfer to a variety of malignant tumors.
