Proteolytic cleavage of translation initiation factors is a means to interfere with mRNA circularization and to induce translation arrest during picornaviral replication or apoptosis. It was shown that the regulated cleavages of eukaryotic initiation factor (eIF) 4G and poly(A)-binding protein (PABP) by viral proteinases correlated with early and late arrest of host cap-dependent and viral inte...

viral myocarditis is a common cardiovascular disease, which has greatly threatened human health. however, up to now, the pathogenesis of viral myocarditis has been unclear, which leads to the lack of its effective treatments. to investigate the role of chemokines in pathogenesis of viral myocarditis, mrna expression for a panel of 19 chemokines detected by rt-pcr in myocardial tissue of balb/c ...

BACKGROUND Studies regarding coxsackievirus A6 (CVA6) infection were limited. In Taiwan, outbreaks of CVA6 occurred in 2009 and 2010, respectively, but the clinical manifestations were markedly different. We conducted a study to compare the clinical features and genomic sequence between the two years. METHODOLOGY/PRINCIPAL FINDINGS In 2009 and 2010, 205 patients with coxsackievirus A6 (CVA6) ...

Mice infected with myopathic coxsackievirus B1 Tucson (CVB1(T)) develop chronic inflammatory myopathy (CIM) consisting of hind limb weakness and inflammation. Amyopathic virus variants are infectious but attenuated for CIM. In this report, viral clones, chimeras, and sequencing were used to identify viral determinants of CIM. Chimeras identified several regions involved in CIM and localized a w...

Rhino- and enteroviruses encode two proteinases, 2A and 3C, which are responsible for the processing of the viral polyprotein and for cleavage of several cellular proteins. To identify further targets of the 2A proteinase of human rhinovirus serotype 2 (HRV2), an in vitro cleavage assay followed by two-dimensional electrophoresis was employed. Cytokeratin 8, a member of the intermediate filamen...

Coxsackievirus B4 (CVB4) can cause a broad range of diseases such as aseptic meningitis, meningoencephalitis, myocarditis, hepatitis, pancreatitis, gastroenteritis, necrotizing enterocolitis, pneumonia and sudden death in the neonates. CVB4 has also been implicated as a possible etiological agent for type 1 insulin dependent diabetes mellitus (IDDM). In this study, the possibility of RNA interf...
