Summary

Automatic Translation

Medfødte forsvar mod virusinfektioner er udløst af mønstergenkendelse receptorer (PRRS). De to cytoplasmatiske PRRs RIG-I og PKR binder til virale signatur RNA'er, ændre kropsbygning, oligomerisere og aktivere antiviral signalering. Metoder er beskrevet som tillader bekvemt overvåge konformationelle kobling og oligomerisering af disse cytoplasmatiske PRRs.
