应用
cGAMP 钠盐已用于 cGAS-cGAMP 活性测定。
生化/生理作用
cGAMP 诱导细胞因子（干扰素-β，干扰素-γ）激活树突状细胞和 CD8 + T 细胞交叉致敏。通过这一操作，促进天然免疫反应。cGAMP 具有抗肿瘤活性，在癌症治疗中首选用于免疫治疗。
环腺苷酸-GMP (cGAMP) 是几种天然存在的环二核苷酸之一，作为细菌第二信使调控原核生物中控制细菌存活、黏附、定植、生物膜形成和毒力因子产生的重要信号机制。霍乱时 c-AMP-GMP 通过下调趋化性促进肠道定植。在感染过程中，细菌 cGAMP 与宿主 STING（干扰素基因刺激物）结合，激活先天免疫应答，导致干扰素基因的表达。

Cyclic dinucleotides (CDNs) are key secondary messenger molecules produced by cyclic dinucleotide synthases that trigger various cellular signaling cascades from bacteria to vertebrates. In mammals, cyclic GMP-AMP synthase (cGAS) has been shown to bind to intracellular DNA and catalyze the

Manganese (Mn) is essential for many physiological processes, but its functions in innate immunity remain undefined. Here, we found that Mn2+ was required for the host defense against DNA viruses by increasing the sensitivity of the DNA sensor cGAS and
