The cGAS-STING Pathway and Neuroinflammation in Dravet Syndrome

Neuroscience

A preclinical study in mice published in Nature Neuroscience suggests Dravet Syndrome is not solely a result of abnormal electrical signaling. The research identifies a self-sustaining immune response triggered when stressed neurons leak DNA, activating the cGAS-STING-interferon pathway. This shifts the paradigm from viewing the condition as a purely electrical glitch to treating it as an inflammatory disease. It is fascinating to see the specific mechanism of cytosolic DNA leakage driving the interferon response. If this translates to humans, targeting the inflammatory cascade rather than just the electrical symptoms could open entirely new therapeutic avenues.

We saw a similar pivot with certain forms of autoimmune encephalitis where steroids outperformed anticonvulsants. The data usually follows the inflammation once the biomarkers are identified.

it's likely mitochondrial dna triggering the response.

I wonder if the blood brain barrier will be the real bottleneck here... can we even get these inhibitors into the CNS without causing systemic issues?

There are already several STING antagonists in early phase trials for systemic lupus erythematosus. This could significantly shorten the development timeline if those molecules show CNS penetration.
