The crystal structure of coxsackievirus B3 (CVB3) has been determined to 3.5 A resolution. The icosahedral CVB3 particles crystallize in the monoclinic space group, P2(1), (a = 574.6, b = 302.1, c = 521.6 A, beta = 107.7 degrees ) with two virions in the asymmetric unit giving 120-fold non-crystallographic redundancy. The crystals diffracted to 2.7 A resolution and the X-ray data set was 55% co...
(along with her daughter) systemic symptoms characteristic of coxsackievirus infection preceding her visual symptoms. However, the acute and convalescent coxsackievirus antibody titers that were obtained in the woman were not abnormal. There have been several reports of coxsackievirus infection associated with chorioretinitis, and the lesions described bear some resemblance to UAIM. Coxsackievi...
Enteroviruses are the causative agents of a number of diseases in humans. Group B coxsackieviruses are believed to be the most common viral agents responsible for human heart disease. Genomic data of enteroviruses has allowed developing new molecular approaches such as Nucleic Acid Sequence Based Amplification (NASBA) for detection of such viruses. In this study, coxsackievirus B3 (CVB3) was de...
RATIONALE Viral myocarditis is a life-threatening illness that may lead to heart failure or cardiac arrhythmias. A major causative agent for viral myocarditis is the B3 strain of coxsackievirus, a positive-sense RNA enterovirus. However, human cardiac tissues are difficult to procure in sufficient enough quantities for studying the mechanisms of cardiac-specific viral infection. OBJECTIVE Thi...
We present a case of fetal-neonatal acute myocarditis caused by coxsackievirus B3 infection in a term neonate. The condition manifested as high-grade atrioventricular (A-V) block prenatally. After delivery, various arrhythmias such as high-grade A-V block, ventricular tachycardia, and junctional ectopic tachycardia appeared, and we had difficulty managing these arrhythmias. This is the first re...
The 5' UTR of Coxsackievirus B3 (CVB3) contains internal ribosome entry site (IRES), which allows cap-independent translation of the viral RNA and a 5'-terminal cloverleaf structure that regulates viral replication, translation and stability. Here, we demonstrate that host protein PSF (PTB associated splicing factor) interacts with the cloverleaf RNA as well as the IRES element. PSF was found t...
Amiloride derivatives are known blockers of the cellular Na(+)/H(+) exchanger and the epithelial Na(+) channel. More recent studies demonstrate that they also inhibit ion channels formed by a number of viral proteins. We previously reported that 5-(N-ethyl-N-isopropyl)amiloride (EIPA) modestly inhibits intracellular replication and, to a larger extent, release of human rhinovirus 2 (HRV2) (E. V...
