Gene therapy with recombinant viral vectors such as adenovirus and adenovirus-associated virus holds great promise in treating a wide range of diseases because of the high efficiency with which the viruses transfer their genomes into host cells in vivo. However, the activation of the host immune responses remains a major hurdle to successful gene therapy. Studies in the past two decades have el...
Recombinant vectors can be used to deliver antigens and to stimulate immune responses in humans. Viral vectors possess various intrinsic properties which may lend to advantages and disadvantages for usage for a given therapeutic application [reviewed by Larocca and Schlom] [1]. The safety and flexibility of recombinant viral vectors have lead to their usage in gene therapy, virotherapy, and vac...
Recombinant human adenovirus serotype 5 (HAd5V) vectors are gold standards of T-cell immunogenicity as they efficiently induce also humoral responses to exogenous antigens, in particular when used in prime-boost protocols. Some investigators have shown that pre-existing immunity to adenoviruses interferes with transduction by adenoviral vectors, but the actual extent of this interference is not...
Porcine circovirus 2 (PCV2) has been implicated as the etiological agent of some diseases, mainly postweaning multisystemic wasting syndrome (PMWS) and porcine dermatitis and nephropathy syndrome (PDNS). The capsid (Cap) protein encoded by the PCV2 ORF2 gene may be an excellent candidate for vaccination. In this study, the Cap protein gene was amplified by PCR, and cloned into the transfer vect...
A recombinant adenovirus (Ad) expressing Cre recombinase derived from bacteriophage P1 was constructed. To assay the Cre activity in mammalian cells, another recombinant Ad bearing an on/off-switching reporter unit, where a LacZ-expression unit can be activated by the Cre-mediated excisional deletion of an interposed stuffer DNA, was also constructed. Co-infection experiments together with the ...
The generation and analysis of a novel combination of recombinant adenovirus vaccines targeting three tumor antigens as an immunotherapeutic Kwong Y Tsang, Elizabeth S Gabitzsch, Claudia Palena, Justin M David, Massimo Fantini, Anna R Kwilas, Adrian E Rice, Yvette Latchman, James W Hodge, Caroline Jochems, Romaine I Fernando, James Gulley, Ravi A Madan, Christopher R Heery, Joseph P Balint, Fra...
The convergence of phage-displayed peptide libraries and recombinant viral vectors launched a promising new direction in targeted viral gene therapeutics, but the translation of targeting peptides to functional cancer therapeutic agents has been challenging. Here, we report progress in developing a successful strategy to optimize targeted viral infection through adenovirus-displayed, semirandom...
We have previously reported effective gene transfer with a targeted molecular conjugate adenovirus vector through the c-kit receptor in hematopoietic progenitor cell lines. However, a c-kit-targeted recombinant retroviral vector failed to transduce cells, indicating the existence of significant differences for c-kit target gene transfer between these two viruses. Here we demonstrate that conjug...
