Viral sensing. In the cytoplasm, viral dsRNA or ssRNA containing 5'-triphosphate (ppp) is specifically recognized by RIG-I, initiating interferon production. In some cells, free viral nucleic acids, including those released from infected and killed cells, can be internalized by endocytosis and detected by Toll-like receptors in endosomes, also leading to interferon production. These mechanisms may cooperate to detect invading viruses and thence to initiate immune responses.
