STING: The Immune Switch Scientists Just Mapped Completely…

STING: The Immune Switch Scientists Just Mapped Completely Your immune system has a protein called STING. It sits quietly inside your cells. When it detects a threat, a virus, bacterial DNA, a tumour, it switches on. It fires interferon signals. It triggers inflammation. It tells the body to fight. For years, scientists understood what STING does. What they did not fully understand was how and what happens when a single mutation changes that switch. A new study published in Nature just answered that question at the most detailed level ever attempted. The team mapped every possible single amino acid change across the entire STING protein, thousands of variants, and measured exactly what each one does to immune signalling. The result is a c
