| abstractText | BACKGROUND: Coxsackievirus-induced myocarditis can be a serious cause of heart failure. In the absence of a specific antiviral therapy, modulating the host immune response may be protective. Interferons (IFNs)-alpha and -beta perform a fundamental role in innate and adaptive antiviral responses, thereby presenting as candidate therapeutics for coxsackievirus infections. METHODS AND RESULTS: To examine the contribution of IFN-beta in protection from coxsackievirus B3 (CVB3) infection, mice lacking the IFN-beta gene were infected with 10(3) plaque-forming units of CVB3. In contrast to wild-type mice that exhibit an intact IFN-beta response, we observed increased susceptibility to infection (70% mortality), a downregulation of IFN-stimulated gene targets (2'-5' oligoadenylate synthetase, serine/threonine protein kinase, the GTPase Mx), and cardiomyocyte breakdown and disruption in the IFN-beta-/- mice. CONCLUSIONS: Viewed together, these results clearly demonstrate that IFN-beta is important in mediating protection against CVB3-induced myocarditis. |
