We hypothesize that autophagy dysfunction specifically in astrocytes induces motor neuron toxicity through impaired mitophagy, leading to accumulation of damaged mitochondria that release mitochondrial DAMPs and trigger NADPH oxidase (NOX2) activation in adjacent motor neurons. The resulting oxidative stress drives motor neuron death through protein oxidation, lipid peroxidation, and mitochondrial dysfunction. This non-cell autonomous mechanism can be tested by: (1) generating GFAP-Cre;ATG7flox/
This hypothesis proposes that loss-of-function mutations in TBK1 contribute to ALS pathogenesis primarily through disrupted mitochondrial quality control in motor neurons, leading to bioenergetic failure and selective neuronal death. TBK1 normally phosphorylates autophagy receptors OPTN and p62, which are essential for targeting damaged mitochondria for mitophagy. When TBK1 function is lost, defective mitochondria accumulate in motor neurons, causing oxidative stress, ATP depletion, and ultimate
