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