UNLABELLED Viral myocarditis, which is most prevalently caused by coxsackievirus B3 (CVB3), is a serious clinical condition characterized by excessive myocardial inflammation. Recent studies suggest that regulation of protein acetylation levels by inhibiting histone deacetylase (HDAC) activity modulates inflammatory response and shows promise as a therapy for several inflammatory diseases. Howe...
The ds-RNA activated protein kinase (PKR) is a serine-threonine kinase with MW of 68 KDa. It belongs to a family of kinases that control one of the translational initiation factors, eIF2. PKR is produced at high level in response to viral infection. This protein by phosphorylating eIF2 inhibits cellular protein synthesis. In this study, the effect of gamma interferon (IFN-γ), an activator, and ...
Microbial infections cause complicated health influences along with bad economic impacts. In the present investigation, three dominant seaweeds namely, Amphiroa anceps, Corallina officinalis and Sargassum filipendula were collected from different Egyptian sites at Red Sea Mediterranean during autumn 2019. Organic extracts of algae screened for their antibacterial activity against pathogenic bac...
Enterovirus infection in newborn infants is a significant cause of aseptic meningitis and encephalitis. Using a neonatal mouse model, we previously determined that coxsackievirus B3 (CVB3) preferentially targets proliferating neural stem cells located in the subventricular zone within 24 h after infection. At later time points, immature neuroblasts, and eventually mature neurons, were infected ...
Coxsackievirus B3 (CVB3) is the most common pathogen that induces acute and chronic viral myocarditis in children. The cytopathic effect (CPE)-based neutralization test (Nt-CPE) and the plaque reduction neutralization test (PRNT) are the most common methods for measuring neutralizing antibody titers against CVB3 in blood serum samples. However, these two methods are inefficient for CVB3 vaccine...
Enteroviral persistence has been implicated in the pathogenesis of several chronic human diseases, including dilated cardiomyopathy, insulin-dependent diabetes mellitus, and chronic inflammatory myopathy. However, these viruses are considered highly cytolytic, and it is unclear what mechanisms might permit their long-term survival. Here, we describe the generation of a recombinant coxsackieviru...
We cloned the sequence encoding murine interleukin-4 (mIL-4), including the secretory signal, into the genome of CVB3/0, an artificially attenuated strain of coxsackievirus B3, at the junction of the capsid protein 1D and the viral protease 2Apro. Two strains of chimeric CVB3 were constructed using, in one case, identical sequences to encode 2Apro cleavage sites (CVB3/0-mIL4/47) on either side ...
Cardiomyocyte apoptosis is a hallmark of coxsackievirus B3 (CVB3)-induced myocarditis. We used cardiomyocytes and HeLa cells to explore the cellular response to CVB3 infection, with a focus on pathways leading to apoptosis. CVB3 infection triggered endoplasmic reticulum (ER) stress and differentially regulated the three arms of the unfolded protein response (UPR) initiated by the proximal ER st...
Cytokine expression in enterovirus infections of the heart may trigger inflammation and have detrimental effects on myocytes. However, the induction of cytokines in human myocardial cells by cardiotropic enteroviruses, for example, Coxsackievirus B3 (CVB3), was not yet demonstrated. Fibroblasts are the predominant cell type of the myocardial interstitium before inflammatory infiltration develop...
The role of signaling pathways including the mitogen-activated protein kinases (MAPKs) and phosphatidylinositol 3-kinase (PI3K) during viral infection has gained much recent attention. Our laboratory reported on an important regulatory role for extracellular signal-regulated kinases (ERK1/2), subfamily members of the MAPKs, during coxsackievirus B3 (CVB3) infection. However, the role of the PI3...
