Unveiling the role of CXCL8/CXCR2 in intervertebral disc degeneration: A path to promising therapeutic strategies.

ABSTRACT:

Background

Intervertebral disc degeneration(IVDD) is the primary etiology of low back pain and radicular pain. Recent studies have found that chemokines play a role in IVDD, but the underlying mechanism is largely unclear.

Methods

Bioinformatics analysis was employed to screen CXCL8 as the target gene. The expression levels of CXCL8 and CXCR2 were quantified using RT-qPCR, western blot(WB), immunohistochemistry(IHC), and enzyme-linked immuno-sorbent assay(ELISA). In the IVDD mouse model, X-ray images, Safranin O-fast green staining(SO-FG), IHC, and WB were conducted to assess the therapeutic effects of CXCL8 on IVDD. Reactive oxygen species (ROS) production, apoptosis of nucleus pulposus cells (NPCs), and the involvement of the NF-κB pathway were evaluated through WB, flow c
