Research progress on macrophage polarization during the degeneration process of lumbar intervertebral discs [PDF]

Jichu yixue yu linchuang
During pathological progression of lumbar intervertebral disc degeneration (LIDD), macrophage polarization functions as a critical regulatory mechanism through the dynamic transition between M1 and M2 phenotypes.

Vasorin-containing small extracellular vesicles retard intervertebral disc degeneration utilizing an injectable thermoresponsive delivery system

Journal of Nanobiotechnology, 2022
Intervertebral disc degeneration (IDD) is the pathological reason of back pain and the therapeutic approaches are still unsatisfactory. Recently, mesenchymal stem cell-derived small extracellular vesicles (EVs) have emerged as the novel regenerative ...

PACS‐2 Mitigates NPSC Apoptosis and Intervertebral Disc Degeneration by Preserving MAM Integrity via the SP1/LRRK2/Mfn2 Axis

Advanced Science, EarlyView.
This study investigates the role of PACS‐2 in IDD, demonstrating that it suppresses the nuclear translocation of SP1, thereby downregulating its downstream target LRRK2. This reduces LRRK2‐mediated ubiquitination and degradation of Mfn2 through the JNK pathway, preserving MAM integrity and promoting NPSC survival.

Notochord Cells in Intervertebral Disc Development and Degeneration

Journal of Developmental Biology, 2016
The intervertebral disc is a complex structure responsible for flexibility, multi-axial motion, and load transmission throughout the spine. Importantly, degeneration of the intervertebral disc is thought to be an initiating factor for back pain. Due to a

Stem Cells and Exosomes: New Therapies for Intervertebral Disc Degeneration

Cells, 2021
Intervertebral disc degeneration (IVDD) occurs as a result of an imbalance of the anabolic and catabolic processes in the intervertebral disc, leading to an alteration in the composition of the extracellular matrix (ECM), loss of nucleus pulposus (NP ...

Acetylation Regulates ACSL4 Degradation Through Chaperone‐Mediated Autophagy to Alleviate Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Intervertebral disc degeneration is triggered by ACSL4 accumulation‐mediated ferroptosis of nucleus pulposus cells due to CMA dysfunction. KAT2B promotes ACSL4 degradation via CMA through acetylation. AAV‐mediated LAMP2A delivery or engineered exosomes rescue nucleus pulposus cell senescence and disc degeneration.

TWEAK and TSLP in disc degeneration and spontaneous hernia resorption

JOR Spine, 2020
Spontaneous degeneration of an intervertebral disc is caused by inflammation that accompanies exposure of the avascular nucleus pulposus to circulation, triggering an autoimmune inflammatory reaction.

Biomechanical Tolerance of Whole Lumbar Spines in Straightened Posture Subjected to Axial Acceleration [PDF]

, 2017
Quantification of biomechanical tolerance is necessary for injury prediction and protection of vehicular occupants. This study experimentally quantified lumbar spine axial tolerance during accelerative environments simulating a variety of military and ...
