DNA from dying cells activates cGAS to form a dimeric cGAS-DNA complex which synthesizes 2???3???-cGAMP from ATP and GTP. cGAMP binds to STING and activates two pathways, NfkB activation (via IKK activation) and IRF3 via TBK1 activation. IRF3 induces IFNB expression in DC downsteam of STING signaling

But at the same time STING signaling induces IDO activation (production) probably via IFN I/STAT1 pathway and suppress local immunity.
