When reovirus double-stranded ribonucleic acid (dsRNA) was synthesized in vitro by using a large-particulate fraction (LP-fraction) from reovirus-infected L cells, a significant amount of the (3)H-labeled dsRNA product was incorporated into reovirus corelike particles bound to the LP fraction. These corelike particles were found to be indistinguishable from virus core derived by chymotryptic di...

The double-stranded RNA genome of reovirus breaks reproducibly into ten segments upon extraction from purified virions. Reovirus-induced messenger RNA's formed in infected cells correspond in length to these ten genomic segments and some real structural and biological implication must be accorded to the ready manner in which the genome is fragmented on attempted isolation. In the present work w...

Purpose. Oncolytic Reoviruses, as a self-limiting virus, can be used in cancer treatment, because they have the ability to replicate tumor cells selectively and destroy them. Studies show that some immune response proteins may interfere with virus life cycle. So, main aim of this bioinformatic study is check which microRNA able target reovirus inhibitory proteins. Experimental Design. By use on...

Mammalian reovirus (MRV) causes respiratory and intestinal disease in mammals. Although MRV isolates have been reported to circulate several animals, there are no reports on Korean from wildlife. We investigated the biological molecular characteristics of based nucleotide sequence segment 1 gene. In total, 144 swabs wild animals were prepared for virus isolation. Based isolation with specific c...

Irradiation with long wavelength UV light in the presence of 4'-substituted psoralens abolished the in fectivity of reovirus and reovirus subviral particles Photoreaction of intact virions, cores, or genome RNA resulted in the formation of psoralen monoadducts and cross-links, demonstrating that the viral genome RNA in situ is double-stranded. Virus-associated RNA polymerase activity was lost f...

Human mast cells are found in skin and mucosal surfaces and next to blood vessels. They play a sentinel cell role in immunity, recognizing invading pathogens and producing proinflammatory mediators. Mast cells can recruit granulocytes, and monocytes in allergic disease and bacterial infection, but their ability to recruit antiviral effector cells such as natural killer (NK) cells and T cells ha...

During cell entry, reovirus particles with a diameter of 70-80 nm must penetrate the cellular membrane to access the cytoplasm. The mechanism of penetration, without benefit of membrane fusion, is not well characterized for any such nonenveloped animal virus. Lysis of RBCs is an in vitro assay for the membrane perforation activity of reovirus; however, the mechanism of lysis has been unknown. I...

Infection of the chestnut blight fungus, Cryphonectria parasitica, by hypovirus CHV1-EP713 or by reovirus MyRV1-Cp9B21 or MyRV2-CpC18 results in reduced fungal virulence (hypovirulence). However, additional phenotypic changes caused by the two groups of mycoviruses are quite different. We now report that the loss of female fertility and the resulting absence of virus transmission through sexual...

Enteric infection of mice with respiratory enteric orphan virus (reovirus) type 1, strain Lang elicits both humoral and cellular immune responses. To investigate the role of CD8, a/b T-cell receptor (TCR) T cells in mucosal immunity to an enteric pathogen, we examined immune responses and viral clearance following enteric reovirus infection in C57BL/6, B6129F2, and b2-microglobulin-deficient (b...

Mammalian reoviruses display serotype-specific patterns of tropism and disease in the murine central nervous system (CNS) attributable to polymorphisms in viral attachment protein σ1. While all reovirus serotypes use junctional adhesion molecule-A as a cellular receptor, they differ in their utilization of carbohydrate coreceptors. This observation raises the possibility that carbohydrate bindi...
