Scientists are uncovering how STING (stimulator of interferon genes), a critical molecular alarm in our immune system, detects dangers like infections, damaged DNA, and cancer. STING acts as a cellular security system that triggers protective immune responses when activated appropriately. When it malfunctions—either overactivating or failing to activate—it can contribute to various diseases. Understanding STING's mechanisms could lead to new therapeutic strategies for treating infections, cancers, and immune disorders by fine-tuning how our body's alarm system responds to threats.
