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
TBK1 loss-of-function mutations in ALS disrupt microglial metabolic homeostasis by impairing mTOR-dependent metabolic checkpoint signaling and mitochondrial quality control. Under normal conditions, TBK1 phosphorylates ULK1 and AMPK to coordinate autophagy-mediated mitochondrial turnover with oxidative metabolism, enabling microglia to maintain anti-inflammatory M2 polarization. In ALS patients with TBK1 mutations, defective mitophagy leads to accumulation of damaged mitochondria and compensator
