Role of non-coding RNAs in the pathogenesis of viral myocarditis

Viral myocarditis (VMC) is a common inflammatory disease of the myocardium that is characterized mainly by inflammatory cell infiltration and cardiomyocyte necrosis. Coxsackievirus B3 (CVB3) is a common cause of VMC, although major progress has been made in the treatment of VMC, the long-term prognosis is still not ideal and further research is needed. Non-coding RNAs (ncRNAs) are RNA molecules without coding functions and include microRNAs (miRNAs), long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs), which play extensive regulatory roles in gene expression; however, their mechanisms of action in CVB3-induced VMC remain incompletely understood. Here, we review the currently known roles of various ncRNAs in CVB3-induced VMC models, with a focus on cell death, inflammation and viral replication, with the aim of providing a reference for their therapeutic or vaccine development for the treatment of VMC.
