Overview

Narrative review uncovers mechanisms of mitochondrial dysfunction driving endplate chondrocyte senescence, highlighting targeted organelle therapies for intervertebral disc degeneration.

Key Points

To delineate the molecular mechanisms linking mitochondrial homeostatic disruption to endplate chondrocyte senescence and evaluate emerging targeted therapeutic strategies for intervertebral disc degeneration.
Narrative synthesis of recent advances in mitochondrial biology, quality control pathways, and metabolic shifts in endplate chondrocytes.
Evaluation of mitochondria-targeted therapeutic strategies, including antioxidants, NAD+ precursors, mitochondrial transplantation, and cartilage-penetrating nanocarrier delivery systems.
Metabolic shifting from oxidative phosphorylation to glycolysis and mitochondrial reactive oxygen species overproduction activate NLRP3 inflammasome and NF-κB signaling, establishing the senescence-associated secretory phenotype.
Impairment of mitophagy alongside fusion-fission imbalance facilitates the buildup of dysfunctional mitochondria and triggers epigenetic alterations that maintain senescent transcriptional programs.
Mitochondria-focused interventions utilizing NAD+ precursors, antioxidants, and nanocarrier-assisted gene editing present viable therapeutic avenues to restore cartilage matrix integrity.
