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 initiate a pathological cascade where microglia become locked in a senescent state, secreting MMP-9 via the senescence-associated secretory phenotype (SASP), which then generates pathological TDP-43 C-terminal fragments that propagate ALS pathology. The mechanism begins with TBK1 haploinsufficiency disrupting normal microglial homeostasis through impaired NF-κB/IRF3 signaling and defective autophagy, forcing microglia into a senescent
