IL-9 Inhibits Viral Replication in Coxsackievirus B3-Induced Myocarditis

Myocardial injuries in viral myocarditis (VMC) are caused by viral infection and related autoimmune disorders. Recent studies suggest that IL-9 mediated both antimicrobial immune and autoimmune responses in addition to allergic diseases. However, the role of IL-9 in viral infection and VMC remains controversial and uncertain. In this study, we infected Balb/c mice with Coxsackievirus B3 (CVB3),...

RT-PCR Detection of Coxsackievirus B3: A Viral Myocarditis

Backgrounds and Aims: Coxsakievirus B3 (CVB3), one of the six Coxsakievirus B serotypes, is a member of the Enterovirus genus within the Picornaviridae family. CVB3 is an important pathogen of viral myocarditis, which accounts for more than 50% of viral myocarditis cases. The genome of CVB3, like that of other Entroviruses, is a single-stranded, sense, polyadenylated RNA molecule with 7400 nucl...

Myocarditis Coxsackievirus B3-Induced Acute Viral Th17 Cells Contribute to Viral Replication in

Th17 cells contribute to viral replication in coxsackievirus B3-induced acute viral myocarditis.

Acute viral myocarditis (AVMC) is characterized by virus-triggered myocardial inflammation, and Coxsackievirus B3 (CVB3) is the primary pathogen. We previously proved that Th17 cells, besides having proinflammatory effects, were involved in AVMC by enhancing humoral response. However, the relationship between Th17 cells and CVB3 replication remains unknown. In this experiment, we infected BALB/...

Mesenchymal stem cells improve murine acute coxsackievirus B3-induced myocarditis

AIMS Coxsackievirus B3 (CVB3)-induced myocarditis, initially considered a sole immune-mediated disease, also results from a direct CVB3-mediated injury of the cardiomyocytes. Mesenchymal stem cells (MSCs) have, besides immunomodulatory, also anti-apoptotic features. In view of clinical translation, we first analysed whether MSCs can be infected by CVB3. Next, we explored whether and how MSCs co...
