Mitochondrial DNA-Driven AIM2 Inflammasome Activation in Neurodegeneration

h-var-d04a952932

## Molecular Mechanism and Rationale The AIM2 inflammasome represents a critical cytosolic DNA-sensing pathway that becomes aberrantly activated in neurodegeneration through mitochondrial DNA (mtDNA) release. Under conditions of cellular stress, mitochondrial outer membrane permeabilization (MOMP) occurs, liberating mtDNA fragments into the cytoplasm where they are recognized as damage-associated
