Open AccessNUDT2 initiates viral RNA degradation by removal of 5′-phosphates
While viral replication processes are largely understood, comparably little is known on cellular mechanisms degrading viral RNA. Some viral RNAs bear a 5′-triphosphate (PPP-) group that impairs degradation by ...

Antiviral immunity via RIG-I-mediated recognition of RNA bearing 5′-diphosphates
The innate immune receptor RIG-I is shown to sense 5′-diphosphate RNAs as found in some viral genomes in addition to its well characterized activation by RNAs bearing 5′-triphosphate moieties.

cGAS produces a 2′-5′-linked cyclic dinucleotide second messenger that activates STING
Cytosolic DNA induces type I interferon via activation of STING; the immediate STING activator is produced by the recently identified DNA sensor cGAS and is shown here to be an unorthodox cyclic dinucleotide h...
