Mice infected with reovirus develop abnormalities in glucose homeostasis. Reovirus strain type 3 Abney (T3A) was capable of systemic infection of nonobese diabetic (NOD) mice, an experimental model of autoimmune diabetes. Reovirus antigen was detected in pancreatic islets of T3A-infected mice, and primary cultures of pancreatic islets from NOD mice supported T3A growth. Significantly fewer T3A-...

background:avian reoviruses (arvs) are members of theorthoreovirus genus; one of the 12 genera of the reoviridaefamily. the arvs are the cause of some important diseases inpoultry such as reovirus-induced arthritis, tenosynovitis,chronic respiratory disease, and mal-absorption syndrome.objectives: in this study, the presence of arvs in the iranianbreeder flocks was investigated through reverse ...

Reovirus mRNA 5'-terminal caps were 3'-radiolabeled with pCp and as affinity probes for proteins with cap binding activity. A rapid, simple, and sensitive blot assay was devised that could detect cellular cap binding protein in a complex polypeptide mixture. By using this method, cap binding activity was found in detergent-treated influenza virus but not in reovirus or vaccinia virus. Preincuba...

The dominant cancer treatment modalities such as chemotherapy, radiotherapy, and even targeted kinase inhibitors and mAbs are limited by low efficacy, toxicity, and treatment-resistant tumor subclones. Oncolytic viral therapy offers a novel therapeutic strategy that has the potential to dramatically improve clinical outcomes. Reovirus, a double-stranded benign human RNA virus, is a leading cand...

NIH-3T3 cells, which are resistant to reovirus infection, became susceptible when transformed with activated Sos or Ras. Restriction of reovirus proliferation in untransformed NIH-3T3 cells was not at the level of viral gene transcription, but rather at the level of viral protein synthesis. An analysis of cell lysates revealed that a 65 kDa protein was phosphorylated in untransformed NIH-3T3 ce...

The prognosis of pancreatic cancer with peritoneal dissemination has not improved. The aim of this study was to clarify whether oncolytic reovirus is effective against the peritoneal dissemination of pancreatic cancer in an immunocompetent animal model. The hamster pancreatic cancer cells HaP-T1 were inoculated into the peritoneal cavity of the hamster and reovirus (1x10(8) plaque-forming units...

Interferons (IFNs) are cytokines that provide innate protection for essentially all cells in response to viral infections 1 . Viruses can induce IFN-β, which is then secreted and binds to other cells to induce antiviral gene expression and protection in those neighboring cells. Induction of IFN-β is particularly important in protection of cardiac myocytes against reovirus-induced myocarditis (i...

UNLABELLED Most viruses that replicate in the cytoplasm of host cells form neo-organelles that serve as sites of viral genome replication and particle assembly. These highly specialized structures concentrate viral replication proteins and nucleic acids, prevent the activation of cell-intrinsic defenses, and coordinate the release of progeny particles. Despite the importance of inclusion comple...

A rapid, sensitive and highly specific detection method for Aquareovirus based on reverse-transcription polymerase chain reaction (RT-PCR) was developed. Based on multiple sequence alignment of the cloned sequences of a local isolates, the Threadfin reovirus (TFV) and Guppy reovirus (GPV) with Grass carp reovirus (GCRV), a pair of degenerate primers was selected carefully and synthesized. Using...

Two forms of virus particle are released from reovirus-infected cell cultures, infectious reovirus and potentially infectious reovirus (PIV). PIV particle forms have a complete outer coat and are not infectious until the outer coat is altered or removed. The PIV concentration in polluted waters, however, has not been determined. Protamine sulfate precipitation, using 0.25% fetal bovine serum an...
