Abstract
Today, nonalcoholic fatty liver disease remains the most dominant chronic liver disease. Cyclic guanosine monophosphate-adenosine monosphosphate synthase (cGAS) is a cytosolic DNA sensor that catalyzes the synthesis of cyclic guanosine monophosphate, activates stimulator of interferon genes (STING), and releases type-I interferon cytokines to trigger immune responses. Exogenous or endogenous DNA acts as a cGAS ligand to activate the cGAS-STING signaling pathway, which plays a role in hepatitis, nonalcoholic fatty liver disease, liver cancer and other diseases, and affects liver disease progression and metabolism through mechanisms such as autophagy. This article reviews the activation of cGAS-STING pathway and its molecular immunological role in nonalcoholic fatty liver disease progression.
