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].
