Recent studies showed that this pathway is also activated by host DNA aberrantly localized in the cytosol, contributing to increased sterile inflammation; insulin resistance via potential interactions of the cGAS-cGAMP-STING pathway with mTORC1 signaling and apoptosis have been discussed, suggesting its critical role in obesity-induced metabolic diseases [27]. This evidence concerns the gene STING1 and obesity due to melanocortin 4 receptor deficiency.
