Analog of c-di-GMP
2’3’-c-di-GMP is a synthetic analog of the bacterial second messenger 3’3’-cyclic diguanylate monophosphate (c-di-GMP) which differ only by one phosphodiester linkage. c-di-GMP is a potent immunostimulant in mammals. It induces production of type I interferons (IFNs) by directly binding to the endoplasmic reticulum-resident receptor STING (stimulator of interferon genes) [1, 2]. Interestingly, it has been reported that its analog 2’3’-c-di-GMP can induce modest antitumoral activity in animal models . When used at low concentrations in various cellular assays, 2’3’-c-di-GMP induces higher levels of type I IFNs than does c-di-GMP.
STING ligands such as c-di-GMP induce type I IFNs and activate interferon stimulated genes (ISG) through interferon regulatory factors (IRFs). To facilitate their study, InvivoGen has developed stable reporter cells in two well established immune cell models: THP-1 human monocytes and RAW 264.7 murine macrophages. These cells express a reporter gene (SEAP or Lucia luciferase), under control of an IRF-inducible promoter.
