Impaired Chaperone‐Mediated Autophagy Accelerates Intervertebral Disc Degeneration by Inducing MIDN Accumulation to Target TSC2 for Proteasomal Degradation

Advanced Science, EarlyView.
This graphical abstract illustrates how chaperone‐mediated autophagy (CMA) regulates intervertebral disc degeneration (IDD). Under normal homeostasis (B), CMA degrades cytoplasmic Midnolin (MIDN) to maintain proteostasis. Under inflammatory stress (A), impaired CMA leads to cytoplasmic MIDN accumulation.
