Fig. 4. EHV-1-specific IFN response in PBMCs of EHM and non-EHM horses. Cytokine mRNA gene expression of IFN-α (a), IFN-β (b), IRF7 (c) and IRF9 (d). Relative quantities (RQ) represent x-fold increase over average levels observed for the same cytokine prior to experimental infection. #Significant difference (P<0.05) in post-hoc multiple comparison tests comparing different groups. *,†Significant differences (P<0.05) compared to pre-infection values.
