Mouse Response

• Host Strain: C57BL/6
• Vaccination Protocol: Groups of female mice were immunized with replication-incompetent adenoviruses expressing PrV glycoprotein (rAd-gB) by either the intranasal (i.n.) or intramuscular (i.m.) route. For i.m. administration, recombinant adenoviruses (10^6 pfu/mouse) were injected into the anterior tibialis muscle three times at weekly intervals (0, 7, and 14 days). The i.n. immunizations were also performed three times at weekly intervals (0, 7, and 14 days) by depositing 10^6 pfu of recombinant adenovirus onto the nares of deeply anesthetized mice. Control mice were immunized with replication-incompetent adenovirus expressing the LacZ gene (rAd-LacZ) (Han et al., 2008).
• Challenge Protocol: The immunized mice were infected i.n. with the virulent PrV YS strain (10 LD50) two weeks after the final immunization. The challenged mice were examined daily to quantify the number of dead animals. Mice generally began to exhibit clinical signs of illness 3 to 4 days post-challenge (Han et al., 2008).
• Efficacy: Recombinant adenovirus expressing gB (rAd-gB) was found to induce effective protective immunity against a virulent viral infection, regardless of whether it was administered via the muscular or systemic route (Han et al., 2008).
• Host Ifng (Interferon gamma) response
  • Description: In splenocytes and popliteal lymph node cells, IFN-gamma was induced to a significantly higher level in immunized animals as compared to replication-incompetent adenovirus expressing LacZ (rAd-LacZ) vaccinated mice. These elevated levels were detected 2 weeks after the final immunization

• Host Il2 response
  • Description: In splenocytes and popliteal lymph node cells, IL-2 was induced to a significantly higher level in immunized animals as compared to replication-incompetent adenovirus expressing LacZ (rAd-LacZ) vaccinated mice. These elevated levels were detected 2 weeks after the final immunization (Han et al., 2008).

• Host Il4 (interleukin 4) response
  • Description: In splenocytes and popliteal lymph node cells, IL-4 was induced to a significantly higher level in immunized animals as compared to replication-incompetent adenovirus expressing LacZ (rAd-LacZ) vaccinated mice. These elevated levels were detected 2 weeks after the final immunization (Han et al., 2008).
