The hypothesis proposes that MMP-9 (matrix metalloproteinase-9), secreted via the senescence-associated secretory phenotype (SASP) from senescent microglia, disrupts TDP-43 nuclear retention by degrading nuclear import machinery components and nuclear envelope proteins, leading to pathological cytoplasmic mislocalization of intact TDP-43 that drives ALS pathology. Rather than directly cleaving TDP-43, MMP-9 targets key nuclear transport proteins including importin-α and nucleoporin components, a
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.
