cGAMP diammonium
Based on 27 publication(s) in Google Scholar
cGAMP (Cyclic GMP-AMP) 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.

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].
