TBK1 mutations identified in ALS/FTD patients impair phosphorylation of autophagy receptors OPTN and p62, required for selective autophagy and mitophagy, leading to accumulation of ubiquitinated protein aggregates (pmid:28148298). However, the causal chain from autophagy defect to cellular senescence remains undemonstrated in ALS models, representing a key gap (pmid:28148298). Similarly, whether TBK1-deficient neurons and glia secrete IFN-β as part of a senescence-associated secretory phenotype
