Gene transfer with adenoviruses having modified fiber proteins

摘要

Methods and compositions for transducing tumor cells using adenoviral vectors which comprise: a chimeric or modified adenovirus fiber protein and the coding sequence for a therapeutic agent, are provided. The chimeric or modified adenovirus fiber protein has at least a portion of an adenovirus fiber shaft of a first serotype and at least a portion of an adenovirus fiber head of a second serotype wherein the adenovirus comprising such a chimeric or modified adenovirus fiber protein exhibits enhanced transduction of tumor cells.
