Lumbar disc herniation (LDH) is a major cause of sciatica, but the underlying mechanisms
are not well understood. Chemokine CCL2 has been implicated to play a vital role in the
neuroinflammation and central sensitization after spinal nerve ligation. Here we investigated
the expression and the role of CCL2 and its receptor CCR2 in LDH-induced pain.
Implantation of autologous nucleus pulposus induced persistent pain hypersensitivity,
associated with increased mRNA expression of CCL2 and CCR2 in the dorsal root ganglion …
