Abstract: The invention provides a method of identifying an antigen from a pathogen or a disease antigen comprising the use of an adenoviral vector array comprising two or more different adenoviral vectors, wherein each adenoviral vector comprises a nucleic acid sequence encoding a different antigen of a pathogen. The adenoviral vectors are administered to antigen presenting cells (APCs) in vitro or to an animal in vivo. The immunogenicity of the antigen is measured by screening for an immune response from effector T lymphocytes in vitro and by screening for the absence of pathogen-induced disease onset in vivo.

Abstract: The invention is directed to a method of delivering a gene product to an animal. The method comprises administering an expression vector comprising a nucleic acid sequence operably linked to a promoter and encoding a gene product, and upregulating transcription of the nucleic acid sequence in the ocular cell. The expression vector can be an adenoviral vector. The invention further provides a method of prophylactically or therapeutically treating an animal for at least one ocular-related disorder. The method comprises contacting an ocular cell with an expression vector comprising a nucleic acid sequence encoding an inhibitor of angiogenesis and/or a neurotrophic agent. In one aspect, the method further comprises upregulating transcription of the nucleic acid sequence. Preferably, if 2×108 adenoviral particles of the inventive method are administered to a mouse, the level of expression of the nucleic acid sequence is not diminished more than ten-fold at 28 days post-administration.

Abstract: The present invention is directed to a method of prophylactically or therapeutically treating an animal for at least one ocular-related disorder, e.g., ocular neovascularization or age-related macular degeneration. The method comprises contacting an ocular cell with an expression vector comprising a nucleic acid sequence encoding an inhibitor of angiogenesis and the same or different nucleic acid sequence encoding a neurotrophic agent. The method also can comprise contacting an ocular cell with different expression vectors, each comprising a nucleic acid sequence encoding an inhibitor of angiogenesis and/or a nucleic acid sequence encoding a neurotrophic agent. In addition, the present invention provides a viral vector comprising a nucleic acid sequence encoding pigment epithelium-derived factor (PEDF) or a therapeutic fragment thereof.

Abstract: The present invention provides a library of viral vectors, wherein each member comprises a first heterologous DNA encoding a first gene product and a second heterologous DNA encoding a second gene product. The first heterologous DNA is common to each member of the library, while the second heterologous DNA varies between members of the library. The present invention additionally provides a method of constructing a library of viral vectors. The method comprises carrying out homologous recombination between a first DNA molecule and a second DNA molecule to form a pool of intermediate viral vector genomes. One or more linear third DNA molecules are ligated into the pool of intermediate viral genomes to produce a library of viral vector genomes. Alternatively, homologous recombination between linear DNA molecules and recipient DNA molecules produces a library of viral vector genomes. The library of viral vector genomes is converted into a library of viral vectors.
