The cGAS-STING pathway drives neuroinflammation in ALS through aberrant recognition of cytoplasmic mitochondrial DNA released following TDP-43 pathology. Rather than targeting the downstream effector STING, therapeutic intervention at the upstream sensor cGAS (MB21D1) offers a more proximal approach to pathway inhibition. cGAS contains a distinct N-terminal DNA-binding domain and C-terminal nucleotidyltransferase catalytic domain connected by a flexible linker region. Upon mtDNA binding, cGAS un
## **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
