Abstract

As one of the most common foodborne transmitted zoonotic pathogens, S. Typhimurium infection causes diarrheal disease in humans and animals. S. Typhimurium infection has been implicated as an inducer for the type I interferon (IFN) response in macrophages, but the mechanisms are not fully understood. In this study, we reported that in addition to TLR4-dependent response, the cytosolic surveillance pathway (CSP) cGAS-STING is also required for the activation of type I IFN response during S. Typhimurium infection.
