Tumor necrosis factor-alpha (TNF-α), a key pro-inflammatory cytokine, has been implicated in modulating both peripheral and central pain pathways.

This narrative review explores the mechanistic pathways through which TNF-α contributes to pain sensitization and highlights the role of TNF-α inhibitors in disrupting these pathways. Evidence suggests that these biologics not only reduce synovial inflammation but also modulate neuroinflammatory circuits, altering pain perception at the spinal and supraspinal levels. Despite their clinical success, variability in patient response and concerns regarding long-term safety necessitate further research into personalized therapeutic strategies.
