Non-canonical STING-PERK pathway dependent epigenetic regulation of vascular endothelial dysfunction integrating IRF3 and NF-B in inflammatory response.

Inflammation-driven endothelial dysfunction is the major initiating factor in atherosclerosis, while the underlying mechanism remains elusive. Here, we report that the non-canonical stimulator of interferon genes (STING)-PKR-like ER kinase (PERK) pathway was significantly activated in both human and mice atherosclerotic arteries. Typically, STING activation leads to the activation of interferon regulatory factor 3 (IRF3) and nuclear factor-kappa B (NF-B)/p65, thereby facilitating signals and inflammation.
