CGAS and cancer: This activation promotes IFN responses in cancerous cells via the cGAS‐STING response, thereby triggering DC maturation.117 Mature DCs present tumor‐associated antigens on MHCI and stimulate CD8+ T‐cell priming to eradicate cancer cells through the immune system.116 Li et al. reported that STING regulator cGAMP retains a robust antitumor response by stimulating STING‐dependent immunity in a mouse model.
