Abstract
The present invention relates to the field of viral gene therapy. More specifically, the present invention provides compositions and methods for retargeting virus constructs. In one embodiment, the present invention provides an adenoviral construct comprising a nucleic acid encoding the peptide sequence MAE-X-PDP (SEQ ID NO:45), wherein X is an antigen targeting peptide. In a more specific embodiment, an adenoviral construct comprises a nucleic acid sequence encoding the peptide sequence MAEWQPDTAHHWALTLPDP (SEQ ID NO:10) inserted into the HI-loop of adenovirus fiber protein. In yet another embodiment, the present invention provides a method for optimizing adenoviral infection of target cells comprising the steps of (a) generating a peptide-display adenovirus library, wherein the displayed peptide is a peptide that specifically binds an antigen expressed on the surface of a target cell, and wherein the displayed peptide is flanked by random peptide sequences; and (b) screening the peptide-display adenovirus library against the target cells.
