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. The Cell (
This hypothesis proposes that precise, neuron-specific TFEB modulation at optimal levels, combined with trehalose co-treatment, can restore lysosomal function in Alzheimer's disease while avoiding the detrimental effects of global TFEB activation. Building on the 'Goldilocks principle' that TFEB requires precise dosing to avoid toxicity, we will use neuron-specific promoters (such as CaMKII or synapsin) to drive moderate TFEB overexpression exclusively in excitatory neurons of AD-affected brain
