Structural modification of RNA by adenosine-to-inosine editing renders self-RNA invisible to RNA sensors of the innate immune system. Lack of RNA editing unleashes inflammatory responses that can lead to autoinflammation. A deeper understanding of the associated signalling pathways might reveal potential targets for drug discovery for autoinflammatory diseases.
