Bis-(3'-5')-cyclic dimeric adenosine monophosphate (c-di-AMP) is a bacterial second messenger implicated in the control of cell wall metabolism, osmotic stress responses and sporulation.
Detection of c-di-AMP by the host cytoplasmic surveillance pathway (CSP) is known to elicit type I IFN responses through a signaling axis that involves STING, TBK1 and IRF3 [1, 2].
Involvement of the helicase DDX41 in the recognition of c-di-AMP has been suggested .
Recent studies have also demonstrated that c-di-AMP exerts strong adjuvant activities when delivered by the mucosal route [4, 5].

THP1-Dual™ cells were stimulated for 24 hours with the STING ligands as shown (all at 10 μg/ml). IRF induction was determined by measuring the relative light units (RLUs) in a luminometer using QUANTI‑Luc™, a Lucia luciferase detection reagent.
THP1-Dual™ cells were stimulated for 24 hours with the STING ligands as shown (all at 10 μg/ml). NF‑kB induction was determined using QUANTI‑Blue™, a SEAP detection reagent, and by reading the optical density (OD) at 655 nm. Non-induced cells (NI) have been included as a negative control.
