Abstract
En 中文
Lysosomes are membrane-bound organelles that orchestrate a wide range of cellular processes, including degradation, metabolism, signaling, gene regulation and quality control, while interacting with other organelles, thereby profoundly shaping cellular homeostasis and fate. Lysosomal membrane integrity is highly vulnerable to a broad spectrum of physiological and pathological insults, acting as both a cause and a consequence of diverse human conditions, including neurodegeneration, cancer, infectious disease and aging. Understanding the mechanisms by which cells respond to lysosomal damage is therefore of critical importance. Recent studies have revealed that cells deploy sophisticated damage response mechanisms locally to repair, remove, and replace damaged lysosomes. In contrast, how local lysosomal damage triggers global cellular responses is only beginning to be understood. This review summarizes recent conceptual advances in global cellular responses to lysosomal damage, encompassing translational, metabolic and transcriptional adaptations, and highlights their crucial roles in restoring cellular homeostasis and shaping outcomes in health and disease.
