The application of naked DNA containing type I interferon (IFN) transgenes is a promising potential therapeutic approach for controlling chronic viral infections. Herein, we detail the application of this approach that has been extensively used to restrain ocular HSV-1 infection, for antagonizing vaginal HSV-2 infection. We show that application of IFN-alpha 1, -alpha 5, and -beta transgenes to vaginal mouse lumen 24 hours prior to HSV-2 infection reduces HSV2 mediated mortality by 2.5 to 3-fold. However, other type I IFN transgenes (IFN- alpha 4, -alpha 5, -alpha 6, and -alpha 9) are non effectual against HSV-2. We further show that the efficacy of IFN-alpha 1 transgene treatment is independent of CD4+ T lymphocytes. However, in mice depleted of CD8+ T lymphocytes, the ability of IFN-alpha 1 transgene treatment to antagonize HSV-2 was lost.
