Figure 3 Myocardial cytokine mRNAs after encephalomyocarditis virus (EMCV)-induced myocarditis inoculation. Inoculation with EMCV significantly increased the expression of TNF-alpha (A) and IL-1-beta (B) in wild-type (WT) mice, but not in knock-out (KO) mice (n = 10 each). *p < 0.01 vs. WT with PBS inoculation. #p < 0.01 vs. KO with EMCV inoculation.
