The Double-Edged Sentinel: cGAS-STING as a Context-Dependent Regulator of Microglial Senescence and Neuronal Genotoxic Stress in Neurodegeneration.
BACKGROUND Neurodegenerative diseases may continue to progress even when a pathogenic protein aggregate is reduced, suggesting that downstream inflammatory and genotoxic circuits can become partly autonomous. This narrative review examines cGAS-STING as a context-dependent regulator of DNA-stress responses in the agein...
