mechanical stress-mediated ferritinophagy aggravates cartilage endplate degeneration via Piezo1-NCOA4-ZBP1 axis

silencing attenuates Z-mtDNA-ZBP1-NFKB axis-driven IVDD. Collectively, our findings suggest that mechanical overload induces ferritinophagy-dependent CEP degeneration via PIEZO1 activation and subsequent upregulation of the Z-mtDNA-ZBP1-NFKB axis, which might furnish a therapeutic target for IVDD.
