Abstract / Description
Despite the well-known role as degradative organelles, lysosomes have been identified as a central signaling hub in maintaining cellular homeostasis. Lysosomal dysfunction is a well-established driver of cellular senescence and age-related pathologies. However, the precise molecular mechanisms through which lysosomes actively regulate aging remain unclear. Excitingly, latest studies show that lysosomes are not merely passive in aging but may actively govern longevity. In this review we summarize two significant discoveries about lysosome and senescence. Li et al. discovered the lysosomal surveillance response (LySR) and Zhang et al. uncovered transgenerational lysosomal signaling. These pathways substantially contribute to enhanced organismal longevity. We further discuss the transcription factor EB (TFEB) as a central regulator linking lysosomal activity to senescence and tissue homeostasis. Together, these findings reposition lysosomes as dynamic regulators that integrate stress and metabolic cues to modulate aging programs. Therefore, targeting lysosomal signaling emerges as a promising strategy for extending healthspan and mitigating age-related disorders.
