Figure 3From: A novel DNA vaccine expressing the Ag85A-HA2 fusion protein provides protection against influenza A virus and Staphylococcus aureusIFN-γproduction in splenocyte culture 72 h after induced by HA in vitro. * P < 0.05. HA induced higher IFN-γ titers in the pEGFP/Ag85A-HA2 group (P < 0.05). Splenocytes from mice vaccinated with pEGFP/Ag85A-HA2 produced 1.5-fold higher IFN-γ in response to HA than those from mice vaccinated with pEGFP/HA2 (P < 0.05).Back to article page
