The cGAS-STING pathway drives neuroinflammation in ALS through aberrant cytoplasmic mitochondrial DNA recognition, but therapeutic intervention may be more effectively achieved by targeting the downstream kinase TBK1 rather than STING itself. Following STING activation by cGAMP, the pathway's inflammatory output critically depends on TBK1 (TANK-binding kinase 1), a 729-amino acid serine/threonine kinase that serves as the obligate signal transducer for both type I interferon and pro-inflammatory
## **Molecular Mechanism and Rationale**
The cGAS-STING (Cyclic GMP-AMP Synthase - Stimulator of Interferon Genes) pathway represents a critical innate immune sensing mechanism that has emerged as a key driver of neuroinflammation in amyotrophic lateral sclerosis (ALS). The molecular cascade begins with the aberrant cytoplasmic accumulation of mitochondrial DNA (mtDNA), which occurs as a downstream consequence of TDP-43 (TAR DNA-binding protein 43) pathology - a hallmark feature observed in ove
