cGAMP (Cyclic GMP-AMPP) diammonium functions as an endogenous second messenger in metazoans and triggers interferon production in response to cytosolic DNA. cGAMP diammonium activates stimulator of interferon genes(STING), which activates a signaling cascade leading to the production of type I interferons and other immune mediators^[1][2][3][4].

cGAMP diammonium promotes the antigen-specific proliferation capacity of spleen cells in mice^[2].
cGAMP diammonium directly activates murine and human dendritic cells in vitro^[2].
On stimulation with cGAMP diammonium, 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)^[3].
cGAMP diammonium activates the endoplasmic reticulum (ER)-resident receptor STING, thereby inducing an antiviral state and the secretion of type I IFNs^[4].

cGAMP (5 μg; nostril mucosal adjuvant) diammonium promotes the antigen-specific cytokine production by spleen cells of immunized mice^[2].
