Cyclic diadenylate monophosphate - STING agonist
Cyclic diadenylate monophosphate (c-di-AMP) is a cyclic dinucleotide (CDN) produced by bacteria in which it functions as an essential second messenger [1]. It coordinates bacterial growth, cell wall stability, and responses to stress and plays a crucial role in the establishment of bacterial infection.
CDNs are a relatively new class of adjuvants that have been shown to increase vaccine potency [2]. CDNs activate innate immunity by directly binding the endoplasmic reticulum-resident receptor STING (stimulator of interferon genes), activating a signaling pathway that induces the expression of interferon-β (IFN-β) and also nuclear factor-κB (NF-κB) dependent inflammatory cytokines [3, 4].
Recent studies have also demonstrated that c-di-AMP exerts strong adjuvant activities when delivered by the mucosal route [5, 6].
c-di-AMP VacciGrade™ is a preclinical grade preparation of the cyclic dinucleotide c-di-AMP.
c-di-AMP VacciGrade™ is for research use only, not for use in humans.
