|Title:||Construction and Characterization of Human Adenovirus Recombinants Expressing the Vesicular Stomatitis Virus Glycoprotein Gene|
|Other Titles:||Human Adenovirus Recombinants Expressing the Vesicular Stomatitis Virus Glycoprotein|
|Abstract:||The potential of human adenovirus (Ad) to serve as a vector for expression of heterologous genes was evaluated. An experimental gene, consisting of sequences coding for the glycoprotein of vesicular stomatitis virus (VSV) attached to the promoter and polyadenylation signal of the herpes simplex virus type 1 (HSV-1) thymidine kinase (TK) gene, was inserted into early region 3 of adenovirus, in both orientations. The TK promoter was functional in both orientations. The TK promoter was functional in both orientations and responded to trans-activation by HSV infection. Abundant expression of VSV G however depended on the presence of a second transcript. This transcript was present only in the recombinant carrying the insertion in the orientation parallel to the E3 promoter (AdG12) and was initiated upstream of the insertion, within Ad sequences. The potential of Ad recombinants to serve as vaccine vectors was investigated using the recombinant AdG12. Antibody against VSV G was induced in cows, pigs, and dogs in response to infection with AdG12. Protection of mice, immunized with AdG12, against a lethal challenge with VSV demonstrated the biological effectiveness of this immune response.|
