Rab7 activation restores lysosomal motility and mitophagic flux in iron-overloaded cells, reversing impaired clearance linked to hyper-acidic, enlarged, perinuclear lysosomes.
- Why it matters: Iron overload is associated with autophagy and mitochondrial dysfunction, but how it alters lysosomal dynamics and mitophagy flux is not well defined.
- What they did: Cells exposed to chronic iron overload showed disrupted mitochondrial morphology and lysosomal homeostasis with iron accumulation in both organelles; mitophagy was induced yet flux was impaired, and Rab7 was pharmacologically activated to test rescue.
- The result: Iron overload produced hyper-acidic, degradative lysosomes that were enlarged, perinuclear, and less motile, coinciding with defective mitophagosome maturation; Rab7 activation restored lysosomal motility and mitophagic flux and improved mitochondrial function and cell viability.
