hnRNP A2/B1 is an RNA-binding protein that assembles into axonal RNA granules with Staufen2 (STAU2), mediating the long-range transport of mRNAs (including β-actin, Arp2/3, MAP1B) along microtubules in motor neuron axons. This hypothesis proposes that ALS-linked hnRNP A2/B1 dysfunction (mutations p.P193L, post-translational modification changes) disrupts axonal RNA granule transport, creating a dual defect: (1) insufficient delivery of structural and synaptic protein mRNAs to distal axons, and (
This hypothesis proposes that TBK1 loss-of-function mutations drive ALS pathogenesis by inducing senescence in astrocytes, which then propagate senescent signals to motor neurons through SASP-mediated paracrine mechanisms, ultimately causing neuronal dysfunction and death. Supporting evidence includes the 2025 Nat Commun study showing that TBK1 deletion creates an aged-like transcriptional signature with increased inflammatory gene expression, suggesting cellular senescence induction.
