Cytokine profiles during cowpox virus (CPV) strain Brighton and vaccinia virus (VV) strain Western Reserve infections were characterized in intranasal (i.n.) and intraperitoneal (i .p.) models in BALB/c mice. The time-course of induction and effects of cidofovir treatment on interferon (IFN)-γ, IFN-γ inducible protein (IP)-10, interleukin (IL)-6, and monocyte chemoattractant protein (MCP)-1 were determined. The four models have distinct patterns of cytokine induction. CPV i.p. and VV i.n. infections showed increased induction throughout the time studied. CPV i.n. infection resulted in delayed induction of IFN-γ and IP-10. Cytokine levels were fairly constant during VV i.p. infections. Cidofovir treatment (100 mg/kg/day i.p. for 2 days) significantly reduced certain cytokine levels in the four models. Treatment did not affect IP-10 in the CPV i.n. model; IFN-γ and IP-10 in the CPV i.p. model; or IL-6, IP- 10, and MCP-1 in the VV i.p. model. Characterization of cytokine responses has implications for understanding the immune responses and pathogeneses of viral infections in these models.
