Viruses with Double-stranded RNA Genomes

Double-stranded RNA poses puzzle.

Microglia Recognize Double-Stranded RNA

double-stranded rna viral infection in tehran trichomonas vaginalis isolates.

background : trichomonas vaginalis is a pathogenic protozoon and may be contaminated with dsrna virus called trichomonas vaginalis virus (tvv). the viral infection is an important factor for its patho-genesis and sensitivity to metronidazole. the presence of tvv is associated with qualitative and quantitative expression of cysteine proteinases and surface immunogenic; p270. the purpose of this ...

A new double-stranded RNA binding protein (DRBP-120) is associated with double-stranded RNA-activated protein kinase (PKR).

Double-stranded RNA-activated protein kinase (PKR) plays an important role in interferon-induced antiviral responses, and is also involved in intracellular signaling pathways, including the apoptosis, proliferation, and transcription pathways. In this study, a new 120-kDa PKR-associated protein designated double-stranded RNA binding protein (DRBP)-120 was identified using co-immunoprecipitation...

Factors affecting the spread of double-stranded RNA viruses in Aspergillus nidulans.

Viruses are common in asexual Aspergilli but not in sexual Aspergilli. We found no viruses in 112 isolates of the sexual Aspergillus nidulans. We have investigated factors that could play a role in preventing the spread of mycoviruses through populations of A. nidulans. Experiments were performed with A. nidulans strains infected with viruses originating from A. niger. Horizontal virus transmis...
