The hypothesis proposes that MMP-9 (matrix metalloproteinase-9), secreted via the senescence-associated secretory phenotype (SASP) from senescent microglia, generates pathological C-terminal fragments of TARDBP (TDP-43) that propagate ALS pathology through cytoplasmic aggregation seeding. High-strength evidence from TDP-43 ALS mouse models demonstrates that reactive microglia expressing MMP-9 remodel perineuronal nets around motor neurons, suggesting a mechanistic link between MMP-9 expression a
The hypothesis proposes that loss-of-function mutations in TBK1 contribute to ALS pathogenesis by trapping microglia in a senescent, pro-inflammatory state characterized by the Senescence-Associated Secretory Phenotype (SASP), thereby accelerating disease progression. Supporting evidence includes a 2025 Nat Commun study demonstrating that microglia-specific TBK1 deletion in an ALS/FTD mouse model reproduces an aged-like transcriptional signature with increased inflammatory gene expression.
