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
This hypothesis proposes that TBK1 loss-of-function mutations drive ALS pathogenesis through a two-step mechanism: first, TBK1-deficient microglia adopt a senescent state and release SASP factors (TNF-α, IL-1β, type I interferons) that act as paracrine stressors on motor neurons; second, these inflammatory signals chronically activate the Integrated Stress Response (ISR) in motor neurons, leading to pathological eIF2α phosphorylation and catastrophic repression of axonal protein synthesis.
