title: Manipulation of the immune response to a plasmid-encoded viral antigen by coinoculation with plasmids expressing cytokines.
abstract: Inoculation of plasmid vectors encoding a viral protein into muscle tissue was shown to result in expression of the transantigen and, consequently, an antiviral immune response. Here, we show that coinoculation of a plasmid expressing the glycoprotein of rabies virus with plasmids encoding mouse cytokines modulated the immune response to the viral protein. Coinoculation with a vector expressing mouse granulocyte-macrophage colony-stimulating factor (GM-CSF) enhanced the B and T helper cell activity to rabies virus, while coinoculation with a plasmid expressing interferon-gamma (IFN gamma) resulted in a decrease of the immune response to the viral antigen.
