cGAS-STING Targeting Offers Novel Therapeutic Opportunities in Liver Diseases.

Cyclic GMP/AMP (cGAMP) synthase (cGAS), coupled with the endoplasmic reticulum (ER)-anchored adaptor protein stimulator of interferon genes (STING), constitute key components of the type 1 interferon signaling network. cGAS detects both pathogen-derived DNA and aberrant cytosolic self-DNA, establishing the cGAS-STING pathway as a central player in autoimmune disorders, sterile inflammation, and senescence-related processes. However, sustained abnormal activation of this signaling axis is implicated in the pathogenesis of chronic inflammatory and autoimmune conditions.

The activation of cGAS-STING pathway offers novel therapeutic opportunities in cancers.

The cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) pathway are crucial elements of the type I interferon (type I IFN) response. cGAS senses both exogenous and endogenous DNA within cells, labeling cGAS-STING as a pivotal anti-tumor immunity mechanism, autoimmunity, sterile inflammatory responses, and cellular senescence. The cGAS-STING pathway, a pivotal innate immune axis, modulates tumorigenesis via diverse effector responses.
