Adenoviruses having altered hexon proteins

摘要

An adenovirus wherein at least one portion of at least one loop region of the hexon is changed. In one embodiment, the adenovirus, prior to modification, is of a first serotype, and at least a portion of at least one loop region of the hexon is removed and replaced with at least a portion of at least one loop region of the hexon of an adenovirus of a second serotype. Such modified adenoviruses do not have epitopes which are recognized by neutralizing antibodies to the unmodified adenovirus of the first serotype.
