摘要：
The crystal structures of human STING in the apo and c-di-GMP–bound states, supported by mutagenesis and biochemical data, reveal that c-di-GMP binds to preformed dimeric STING. c-di-GMP prolongs STING phosphorylation in vitro, which may contribute to downstream IFN signaling. These findings aid in understanding the innate immune response to bacterial infection.
