CGAS and Stroke: After the ictus of brain ischemic attack, cytosolic double‐stranded DNA (dsDNA) released by necrotic neuronal cells is a potential damage‐associated molecular pattern (DAMP), the underlying mechanisms of brain inflammation on dsDNA recognition by nucleic acid‐sensing cyclic GMP‐AMP (cGAMP) synthase (cGAS) following stroke have not been explored to date.
