The past decades have witnessed significant progress in discovery and characterize cytosolic DNA sensing and signaling, especially the understanding of the stimulator of interferon genes (STING). This pathway to foreign nucleic acids enables the initiation of robust anti-pathogenic responses to protect the host, and provides a new understanding for therapeutic intervention in a growing infectious disease, including chlamydial infection. Chlamydiae are obligate intracellular pathogenic bacterium causing widespread human diseases such as sexually transmitted infections and respiratory tract infections. Previous studies have shown that IFN production and autophagy are well recognized as being two critical processes induced by STING, and these two processes were also activated during chlamydial infection. In this review, we summarize the important characteristics of the STING activation pathway and recent snapshots about the role of STING in chlamydial infection. Studying the role of STING in chlamydial infection could provide valuable information to further understand the pathogenesis and treatment of chlamydial infection.
