This article examines how declining chaperone-mediated autophagy with age affects senescent-cell biology and immune clearance, offering a translational research perspective.
Key Takeaways
- Autophagy dysfunction and senescence are established drivers of aging, but their potential interaction remains poorly understood.
- Here we show that age-related decline of chaperone-mediated autophagy (CMA), a pathway for selective lysosomal protein degradation, changes senescent cell properties and impairs their immune clearance.
- Their senescence-associated secretory phenotype exhibits enhanced pro-senescence effects on neighboring cells and inhibits macrophage CMA, which impairs their ability to engulf senescent cells.
