| 产品描述: | cGAMP (Cyclic GMP-AMPP) disodium 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 |
| 靶点: |
Human Endogenous Metabolite |
| 体外研究: |
cGAMP disodium 促进小鼠脾细胞抗原特异性增殖能力。 CGAMP二钠在体外直接激活小鼠和人树突状细胞。 在用 cGAMP disodium 二钠刺激时,患者的成纤维细胞显示出 IFNB1 的转录增加,但编码白细胞介素 1 (IL1)、白细胞介素 6 (IL6) 或肿瘤坏死因子 (TNF) 的基因的转录没有增加。 cGAMP disodium 激活内质网 (ER) 驻留受体 STING,从而诱导抗病毒状态和 I 型干扰素的分泌 |
| 体内研究: |
cGAMP disodium (5 μg;鼻黏膜佐剂) 促进免疫小鼠脾细胞产生抗原特异性细胞因子。 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. |
