PIEZO1‐GPX4 Axis Mediates Mechanical Stress‐Induced Vertebral Growth Plate Dysplasia via Ferroptosis Activation

Advanced Science, EarlyView.
Mechanical stress activates PIEZO1 in vertebral growth plate chondrocytes, triggering ferroptosis through direct binding and inhibition of GPX4. This axis promotes lipid peroxidation and pathological ossification, accelerating spinal deformities. Clinical and genetic evidence (Piezo1‐cKO) confirms its role in scoliosis progression.

Human iPSCs Derived MSCs‐Secreted Exosomes Modulate Senescent Nucleus Pulposus Cells Induced Macrophage Polarization via Metabolic Reprogramming to Mitigate Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Senescent nucleus pulposus cells drive inflammatory M1 macrophage polarization, exacerbating intervertebral disc degeneration (IDD). Conversely, M1 macrophages accelerate NP cell senescence, creating a vicious cycle. iPSCs‐derived mesenchymal stem cell (iMSCs) exosomes break this loop by delivering miR‐100‐5p to suppress mTORC1/glycolysis in ...

Friction in metal-on-metal total disc arthroplasty: effect of ball radius [PDF]

, 2012
Total Disc Arthroplasty (TDA) can be used to replace a degenerated intervertebral disc in the spine. There are different designs of prosthetic discs, but one of the most common is a ball-and-socket combination.

β‐Mangostin Attenuates TET2‐Mediated DNA Demethylation of Prkcg in the Prevention of Intervertebral Disc Degeneration

Advanced Science, EarlyView.
β‐Mangostin alleviates intervertebral disc degeneration through dual modulation of macrophage polarization and the TET2‐Prkcg axis in nucleus pulposus cells. Abstract Intervertebral disc degeneration (IDD) induced lower back pain is a main cause of disability, resulting in a substantial workforce loss worldwide and placing a substantial burden on the ...

Modulating Macrophage–Nucleus Pulposus Cell Crosstalk via Sequential Drug Delivery Attenuates Disc Degeneration

Advanced Science, EarlyView.
The G‐CS/MSN drug delivery system enhances intervertebral disc repair through sequential drug release. Abstract Intervertebral disc degeneration (IDD) is characterized by an inflammatory environment and dysregulation of the extracellular matrix metabolism (ECM).
