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.

The Integrated Stress Response (ISR) controls cellular protein synthesis through eIF2α phosphorylation, but this hypothesis proposes that chronic ISR activation in ALS motor neurons creates a pathological cascade that specifically disrupts mitochondrial protein homeostasis and bioenergetics. In ALS, chronic eIF2α~P elevation (>0.7 normalized phosphorylation) caused by proteostatic stress from TDP-43/FUS aggregates selectively impairs synthesis of nuclear-encoded mitochondrial proteins, including
