The results showed that the expressions of Caspase-1, IL-1β, IL-18 in the DCM group were higher than those in the Control group, and these proteins in the Ad-PRR group were significantly higher than those in the Ad-EGFP group, but there was also no statistical significance between the DCM group and Ad-EGFP group (Figures 2B–D). This evidence concerns the gene IL18 and familial dilated cardiomyopathy.
