Background

C-di-AMP is a STING agonist, which binds to the transmembrane protein STING, thereby activating the TBK3-IRF3 signaling pathway, subsequently triggering the production of type I IFN and TNF. c-di-AMP serves as a second messenger in bacteria, primarily regulating cell growth, survival, and virulence in Gram-positive bacteria, and also modulates the host immune response. As an effective mucosal adjuvant, c-di-AMP stimulates both humoral and cellular responses[1-5]. C-di-AMP have been utilized as vaccine adjuvants for influenza and hepatitis C.Citation[6].

Combination of c-di-AMP(5 ug/ml;48h) with radiation promotes the secretion of type I IFN and ISG levels in BMDCs[7].

C-di-AMP(25ug;i.p;3 times) can synergistically enhance the antitumor effects of Radiotherapy (RT)-associated dsDNA by promoting IFN-β production and CD8+ cytolytic T cell activation in a cGAS- and STING-dependent manner in mice[7].

C-di-AMP是STING(刺激内质网的蛋白)的激动剂,通过与该跨膜蛋白结合,激活TBK3-IRF3信号通路,进而引发I型IFN和TNF的产生。c-di-AMP在细菌中作为第二信使发挥作用,主要调节革兰氏阳性菌的细胞生长、存活和毒力,并调节宿主的免疫反应。作为有效的粘膜佐剂,c-di-AMP可以刺激体液和细胞反应[1-5]。C-di-AMP已被用作流感和丙型肝炎的疫苗佐剂[6]。

C-di-AMP(5 ug/ml;48h)联合放疗可促进BMDCs分泌I型IFN和ISG[7]。

C-di-AMP(25ug;i.p;3 times) 可以协同增强RT相关dsDNA的抗肿瘤作用,通过cGAS-和STING-依赖的方式促进小鼠IFN-β的产生和CD8+细胞溶解T细胞的活化[7]。

Protocol

Cell experiment [1]:
Cell lines	Bone marrow- derived DC(BMDC)
Preparation Method	BMDCs were stimulated with irradiated tumor-supernatants, or c-di-AMP (5 ug/ml) or a combination for 48 h on day 7.
Reaction Conditions	5 ug/ml;48h
Applications	Combination of c-di-AMP with radiation promotes the secretion of type I IFN and ISG levels.
Animal experiment [2]:
Animal models	C57BL/6 male mice and cGAS KO (Mb21d1-/-) mice
Preparation Method	Mice were injected c-di-AMP intraperitoneally with 25ug one day before radiotherapy, and once every other day, a total of three times.
Dosage form	25ug;i.p;3 times
Applications	C-di-AMP acts as STING agonist, cooperated with dsDNA to promote DC maturation and type I IFN release.
