Autoimmune myocarditis
1Department of Pathology, Johns Hopkins Medical Institutions, Baltimore, Maryland 21205, USA.
We have developed two models of myocarditis in mice. The first is produced by infection with Coxsackievirus B3; the second results from immunization with cardiac myosin. Both forms of myocarditis occur in the same genetically predisposed strains. Genetically resistant mice can be rendered susceptible to myocarditis by co-treatment with cytokines IL-1 or TNF. Moreover, the disease is inhibited by administration of an antagonist of IL-1. These models will be useful for clarifying outstanding issues related to human myocarditis or dilated cardiomyopathy.
