Cyclic GMP-AMP
3',3'-cGAMP

cGAMP (Cyclic GMP-AMPP) 作为内源性第二信使发挥作用，并触发干扰素的产生以响应胞浆DNA。cGAMP 激活干扰素基因刺激因子 (STING)，激活导致产生 I 型干扰素和其他免疫介质的信号级联。

生物活性

cGAMP (Cyclic GMP-AMPP) functions as an endogenous second messenger in metazoans and triggers interferon production in response to cytosolic DNA. cGAMP 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].

Endogenous Metabolite

体外研究
(In Vitro)

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

体内研究
(In Vivo)

cGAMP promotes the antigen-specific cytokine production by spleen cells of immunized mice^[2].

Animal Model:	Female C57BL/6 (H-2b) mice 6–8 weeks old^[2]
Dosage:	5 μg
Administration:	Nostril mucosal adjuvant
Result:	Higher titers of ovalbumin (OVA)-specific IgA and total IgG as well as IgG1 and IgG2c in the sera of mice immunized with cGAMP-adjuvanted OVA as compared to sera from OVA-immunized mice.
