In the aging brain, a molecular alarm system evolved to guard against viruses and cellular damage has been found to linger in a state of chronic activation, quietly accelerating the neuronal loss seen in Alzheimer's, Parkinson's, and Huntington's diseases. Scientists have traced this sustained alert to the cGAS-STING immune pathway, which misfolded disease proteins can trigger by causing mitochondria to leak their DNA into places it does not belong. The discovery reframes neurodegeneration not only as a story of toxic accumulation, but as one of a protective system that cannot find its way bac
