When viruses infect the body's cells, those cells face a difficult problem. How can they destroy viruses without harming themselves? Scientists at University of Utah Health have found an answer by ...

Picobirnaviruses (PBVs) are small, non‐enveloped viruses with a bisegmented double‐stranded RNA (dsRNA) genome. Since their initial discovery in 1988, PBVs have been detected in a wide range of hosts ...

Viroid replication generates dsRNA intermediates, which are processed by Dicer into 21- to 25-nucleotide siRNAs. These siRNAs are then incorporated into siRNA – ribonuclease complexes (RISC). If the ...

Double-stranded RNA is a warning flag to the cell, indicating the presence of a virus. In 2004, Takashi Fujita and colleagues at Tokyo Metropolitan Institute of Medical Science identified an ...
