Biological activity
c-di-AMP (Cyclic diadenylate) is a STING agonist, which binds to STING to activate the TBK3-IRF3 signaling pathway, which subsequently triggers the production of type I IFN and TNF. c-di-AMP (Cyclic diadenylate) is a bacterial second messenger, mainly in Gram-positive bacteria, which can regulate cell growth, survival and virulence. c-di-AMP (Cyclic diadenylate) also regulates the host immune response. c-di-AMP (Cyclic diadenylate) can be used as an effective mucosal adjuvant to stimulate body fluid and cell responses.
Target
STING
In vitro studies
c-di-AMP (Cyclic diadenylate) signaling is a central factor in many Gram-positive bacteria regulating cell wall synthesis, potassium ion channels, DNA repair, and biofilm formation. c-di-AMP is also essential for cell growth, survival, and virulence of several well-known human pathogenic bacteria including S. aureus , L. monocytogenes , S. pyogenes , and Mycobacterium spp .
c-di-AMP (Cyclic diadenylate) combines with model antigens, such as OVA or β-Gal, acts as a potent mucosal adjuvant stimulating both humoral and cellular responses.
