During early/prodromal ALS, cGAS/STING activation may be moderate and potentially adaptive (mitophagy induction), while during symptomatic phase it becomes hyperactivated and drives neurodegeneration. Therapeutic timing determines whether STING inhibition is protective or detrimental. This hypothesis introduces a critical clinical development consideration: identifying the therapeutic window for intervention.
Existing STING antagonists (H-151, SN-011, Compound 18) developed for autoinflammatory diseases can be repurposed to block both neuronal and glial cGAS/STING activation downstream of TDP-43-mediated mtDNA release. STING represents the most druggable node in the pathway with well-characterized binding pockets, established structure-activity relationships, and existing tool compounds with moderate-to-excellent CNS penetration. The translational path is accelerated by existing safety data from auto
