Abstract: The present invention provides compositions, methods and kits comprising viral vectors that may be used for performing immunotherapy. In particular, the present invention provides viral vectors having subgroup B adenoviral capsid fibers that are configured to express a transgene sequence in antigen presenting cells (e.g. dendritic cells) with a high transduction efficiency. Preferably, the transgene sequence is a retrogen cassette and the adenoviral capsid fibers are Ad11 fibers.

Abstract: This invention provides modified recombinant Ad vectors (e.g., AdE1− vectors) undergoing defined homologous recombination in order to create predictably rearranged genomic derivatives in a host cell. Genomic rearrangements can be achieved, for example, by incorporating two IR sequences within one vector genome and enabling genomic rearrangement by coinfection with two parental vectors of one type (also referred to herein as a one vector system) or by homologous recombination of overlapping regions in two distinct types of parental vectors (with or without IR sequences) and enabling genomic rearrangement only upon coinfection of the host cell with the two distinct parental vectors (also referred to herein as two vector system).
