Abstract: Hepatitis C recognition Innate immunity is an important defence against infection by viruses, triggered by host recognition of 'PAMPS', or pathogen-associated molecular patterns. Saito et al. have now identified a conserved poly-uridine motif in the 3´ non-transcribed region of the hepatitis C virus genome as the relevant PAMP for detection by the RNA helicase RIG-I, a protein previously shown to have an essential function in double-stranded RNA-induced innate antiviral responses.
