Abstract:
Stimulator of interferon genes ( STING) is a newly discovered adaptor protein in the innate immune system and plays an important role in innate immune response mediated by cytoplasmic DNA. Double-stranded DNA recognition receptors in cells are mediated by STING protein to produce type I interferon and other cytokines. Inadequate innate immune response and anti-hepatitis B virus ( HBV) specific immune response are important causes of chronic HBV infection. This article introduces the discovery of STING and the latest research advances in its structure, briefly elaborates on the mechanism of activation of the STING signaling pathway, summarizes the research advances in the interaction between the STING signaling pathway and HBV, and points out the potential value of STING in clinical treatment.
