  • TNF- ⁇ has a direct cytotoxic and negative inotropic effect on cultured cardiomyocytes and also activates cytotoxic ⁇ cells, which can cause myocyte damage (Pinsky et al., 1995; Yokoyama et al., 1993; Woodley et al., 1991). It has been suggested that TNF-a plays a key role at the very early stages of the immune response, and that administration of anti-TNF-a mAbs can interfere with the early pathways of acute viral myocarditis (Yamada et al., 1994). In this study, treatment with IL-lra may protect myocardium by suppressing iNOS and TNF- ⁇ expression.
  • IL-lra and vIL-10 were both effective treatments in the mouse model of myocarditis of the present invention, but treatment with in vivo electroporation itself was inoculated with EMCV The survival rate of the mice did not change.
  • IL-10 is considered to be an important regulatory response in the early immune response to viral infection. Mortality and inflammation are increased in IL-10 knockout mice with virus-induced encephalomyelitis (Lin et al., 1998). Recently, the present inventors have shown that treatment with recombinant IL-10 reduces mortality and cytoplasmic force-in expression in a mouse model of myocarditis (Nishio et al., 1999).

  • reduced expression of IFN-r was also observed in the vIL-10 treated group.
  • vIL-10 is thought to be a cellular site force captured by the EB virus. However, there are some differences between the effects of IL-10 and vIL-10.
  • vIL-10 is less active as a cytokine synthesis inhibitor than IL-10, it lacks some of the immunostimulatory activity of IL-10 on monocytes, lymphocytes and mast cells. Therefore, vIL-10 may provide excellent immunosuppression (Drazan et al., 1996; Debruyne et al., 1998; Henke et al., 2000). These differences may explain the superior effect of vIL-10 in reducing the effects of myocarditis as compared to IL-10. Recently, the structural basis for the different activities of IL-10 and vIL-10 has been elucidated (Ding et al., 2000). The results suggest that a single amino acid is important for the immunostimulatory activity of IL-10.
  • IL-10 is known to induce IL-Ira by mRNA stabilization, while it suppresses the production of IL_1 ⁇ , TNF and IL-8 (Cassatella et al., 1994; Chomarat et al. , 1995).
  • vIL-10 induces irlra is unknown, but mice transfected with vIL-10 show elevated serum concentrations of IL-Ira (874 pg / ml). This additional effect of vIL-10 may explain its higher efficacy compared to IL-lra.
