Virus-Encoded MicroRNAs Facilitate Gammaherpesvirus Latency and Pathogenesis In Vivo
UNLABELLED Gammaherpesviruses, including Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpesvirus (KSHV, or HHV-8), and murine gammaherpesvirus 68 (MHV68, γHV68, or MuHV-4), are B cell-tropic pathogens that each encode at least 12 microRNAs (miRNAs). It is predicted that these regulatory RNAs facilitate infection by suppressing host target genes involved in a wide range of key cellular p...
متن کاملExpression of Ovine Herpesvirus -2 Encoded MicroRNAs in an Immortalised Bovine – Cell Line
Ovine herpesvirus-2 (OvHV-2) infects most sheep, where it establishes an asymptomatic, latent infection. Infection of susceptible hosts e.g. cattle and deer results in malignant catarrhal fever, a fatal lymphoproliferative disease characterised by uncontrolled lymphocyte proliferation and non MHC restricted cytotoxicity. The same cell populations are infected in both cattle and sheep but only i...
متن کاملIdentification of virus-encoded microRNAs.
RNA silencing processes are guided by small RNAs that are derived from double-stranded RNA. To probe for function of RNA silencing during infection of human cells by a DNA virus, we recorded the small RNA profile of cells infected by Epstein-Barr virus (EBV). We show that EBV expresses several microRNA (miRNA) genes. Given that miRNAs function in RNA silencing pathways either by targeting messe...
متن کاملVirus-encoded microRNAs: future therapeutic targets?
The discovery of microRNAs (miRNAs) is a remarkable breakthrough in the field of molecular genetics, as miRNAs are key actors which regulate gene expression in diverse cellular processes from unicellular yeast to human. The recent discovery of virus-encoded miRNAs indicates that viruses also use this fundamental mode of gene regulation. Research into viral miRNAs function demonstrates that some...
متن کاملDiscovery of herpes B virus-encoded microRNAs.
Herpes B virus (BV) naturally infects macaque monkeys and is a close relative of herpes simplex virus. BV can zoonotically infect humans to cause a rapidly ascending encephalitis with approximately 80% mortality. Therefore, BV is a serious danger to those who come into contact with these monkeys or their tissues and cells. MicroRNAs are regulators of gene expression, and there have been reports...
