cGAMP(Cyclic GMP-AMP) is an endogenous second messenger in metazoans and triggers interferon production in response to cytosolic DNA; STING ligand. Target: in vitro: cGAMP induced IFNβ RNA robustly even at concentrations as low as 10 nM. cGAMP was much more potent than c-di-GMP in inducing IFNβ based on ELISA assays. cGAMP was also more potent than c-di-GMP and c-di-AMP in activating IRF3. cGAMP binds to and activates STING to trigger the downstream signaling cascades. On stimulation with cGAMP, fibroblasts from the patients showed increased transcription of IFNB1 but not of the genes encoding interleukin-1 (IL1), interleukin-6 (IL6), or tumor necrosis factor (TNF). cGAMP activates the endoplasmic reticulum (ER)-resident receptor STING, thereby inducing an antiviral state and the secretion of type I IFNs. in vivo: cGAMP can enhance the adaptive immune response to the model antigen ovalbumin in mice. cGAMP promotes antigen specific IgG and a balanced Th1/Th2 lymphocyte response in immunized mice.
