Abstract:

Coxsackievirus B3 (CVB3), a member of the Picornaviridae family, is considered to be one of the most important infectious agents to cause virus-induced myocarditis. Despite improvements in studying virus pathology, structure and molecular biology, as well as the diagnosis of this disease, there is still no virus-specific drug or vaccine in clinical use. During the last 20 years many investigations have been performed to develop classic and modern immunization techniques against CVB3-induced heart disease. One promising approach among others includes the insertion of coding sequences of cytokines into the viral genome. The application of an IFN-γ-expressing recombinant coxsackievirus vector is especially efficient against CVB3-induced myocarditis. Beside direct IFN-γ-mediated antiviral effects, the local and simultaneous expression of IFN-γ by the virus itself activates the immune system in a strong and long-lasting manner, which protects animals completely against subsequent lethal infections independently of the age of the immunized individual and the route of vaccine administration.
