How does chronic cGAS/STING activation downstream of TDP-43 contribute to progressive neurodegeneration versus acute cell death?

PARTIALLY ADDRESSED

The study identifies cGAS/STING activation as a consequence of TDP-43-mediated mtDNA release, but the temporal dynamics and whether this pathway drives chronic inflammation or acute toxicity remains unclear. This distinction is critical for determining therapeutic timing and approach. Gap type: unexplained_observation Source paper: TDP-43 Triggers Mitochondrial DNA Release via mPTP to Activate cGAS/STING in ALS. (2020, Cell, PMID:33031745)
