Detailed research over the past decade has shown that that the protein stimulator of interferon genes (STING) is a master regulator of type I interferons and as such plays an essential role in activating innate immunity. STING’s importance in orchestrating the body’s response to pathogenic, tumor, or self-DNA in the cytoplasm has made it a hot target in immunology research and drug discovery and several biopharma companies have started programs dedicated to this area spanning infectious and inflammatory diseases as well as cancer.
