Finally, a clear trend was observed for both pairs of 5′-OH and 5′-ppp RNAs between their affinity for FL RIG-I and the extend to which they can stimulate the IFN pathway, confirming that for analyzed RNAs, the presence of 5′-ppp RNA modification is correlated with RIG-I’s enhanced ability to signal (Tables 1 and 2 ).
