Targeting Inflammatory Cell Death: A Strategy for Discogenic Pain Relief

Area of Science:

• Biomedical Science
• Cell Biology
• Pain Research

Background:

• Low back pain from intervertebral disc degeneration (IVDD) is a significant clinical issue.
• Mechanisms of IVDD and associated pain are not fully understood.
• Inflammatory programmed cell death pathways, including pyroptosis, ferroptosis, and necroptosis, are implicated in IVDD progression.

Purpose of the Study:

• To systematically review the mechanisms of pyroptosis, ferroptosis, and necroptosis in IVDD.
• To explain the activation of these cell death pathways in different intervertebral disc regions.
• To summarize therapeutic strategies targeting these pathways for discogenic pain.

Main Methods:

• Literature review of programmed cell death mechanisms in IVDD.
• Analysis of how pyroptosis, ferroptosis, and necroptosis contribute to pain.
• Summary of potential therapeutic interventions targeting these cell death pathways.

Main Results:

• Pyroptosis, ferroptosis, and necroptosis contribute to IVDD and pain by altering the disc microenvironment.
• These pathways release inflammatory factors and disrupt tissue structure.
• Targeting these specific cell death mechanisms shows promise for pain alleviation.

Conclusions:

• Novel cell death mechanisms are key drivers of IVDD-related pain.
• Therapeutic strategies modulating pyroptosis, ferroptosis, and necroptosis offer potential for managing discogenic pain.
• This review provides insights for future clinical management of IVDD pain.
