Interpretive Summary:
Technical Abstract: Interleukin 2 (IL-2) is a soluble cytokine that stimulates the cell-mediated immune response. Virus constructs, such as recombinant vaccinia virus, expressing chicken IL-2 have been shown to improve viral clearance by natural killer cells in mice. We have inserted the open-reading frame of the chicken IL-2 gene into a viscerotropic velogenic Newcastle disease virus backbone (recombinant ZJ1 strain) in order to determine how the expression of IL-2 at the site of infection during viral replication affects the local and systemic immune response, viral replication and viral pathogenesis. Results from embryo inoculation (mean death time), intra-cranial pathogenecity index, cell culture multistep growth curve and chicken pathogenesis experiments will be presented.
