What is the role of double-stranded RNA in antiviral host defense systems?

Animals, insects, and plants use a variety of sensing mechanisms to detect invading pathogens such as viruses. One complex and effective antiviral defense system they share is based on recognition of double-stranded RNA (dsRNA), often produced when a virus invades a host cell. New information leading to a clearer understanding of the mechanisms underlying viral dsRNA sensing is presented in a comprehensive Review article published in Journal of Interferon & Cytokine Research.
