cGAMP (Cyclic AMP-GMP) (Synonyms:Cyclic GMP-AMP; 3',3'-cGAMP)
目录号 : KG12197 CAS No. : 849214-04-6
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 .

生物活性

cGAMP (Cyclic GMP-AMP) 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.

体外研究

cGAMP can enhance the antigen-specific proliferative capacity of mouse splenocytes [1].
cGAMP can directly activate dendritic cells from both mice and humans in vitro [1].
Under cGAMP stimulation, the transcription of IFNB1 increased in the fibroblasts of patients, but there was no increase in the transcription of genes encoding interleukin-1 (IL1), interleukin-6 (IL6), or tumor necrosis factor (TNF). [2].
cGAMP activates the endoplasmic reticulum (ER)-resident receptor STING, thereby inducing an antiviral state and the secretion of type I interferons.

 

体内研究

CGAMP (5 μg; nasal mucosal adjuvant) can promote the production of antigen-specific cytokines by immune mouse spleen cells [1].

 

Animal Model: Female C57BL/6 (H-2b) mice 6–8 weeks old
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.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
