Figure 5. Analysis of innate immune response evidenced in pig corneas as depicted by cytokine and interferon profile of known innate response mediators. Comparison in cytokine profile of uninfected, zinc oxide-treated uninfected, infected and zinc oxide-treated infected cornea samples was undertaken to control for major variables tested, namely, antiviral, zinc oxide tetrapods treated and virus, herpes simplex virus type-1 (KOS)tk12. Significance was determined by t-test: p<0.01.
