The Integrated Stress Response (ISR) is a central regulatory pathway that controls global protein synthesis through phosphorylation of eIF2α (Ser51). In ALS motor neurons, this hypothesis proposes that chronic ISR activation (via PERK, GCN2, HRI, or PKR pathways) caused by proteostatic stress (TDP-43/FUS aggregates), oxidative stress, and ER stress creates a pathological eIF2α~P state that represses axonal protein synthesis below the threshold required for synaptic maintenance and axonal repair,
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.
