Chronic pain syndromes represent a significant global health burden, characterized by persistent pain that extends beyond normal tissue healing. Once considered a purely neuronal phenomenon, chronic pain is now recognized as a complex neuroimmune disorder involving bidirectional communication between the nervous system and immune components. Glial cells particularly microglia and astrocytes have emerged as key modulators of nociceptive signaling through their production of pro-inflammatory and anti-inflammatory cytokines. These cells, activated in response to peripheral nerve injury, infection, or inflammation, contribute to central sensitization by altering synaptic transmission and increasing neuronal excitability. Cytokines such as TNF-α, IL-1β, and IL-6 amplify pain signals, while regulatory cytokines including IL-10 can exert protective effects. This review synthesizes current evidence on the roles of glial activation and cytokine signaling in chronic pain pathophysiology, with an emphasis on neuropathic, inflammatory, and cancer-related pain. We also discuss novel therapeutic strategies targeting neuroimmune interactions, including glial inhibitors, cytokine blockers, and neuromodulatory approaches. Understanding neuroimmune crosstalk provides promising avenues for more precise and effective treatment strategies in chronic pain management.

Keywords: chronic pain, neuroimmune interaction, glial cells, cytokines, central sensitization, microglia, astrocytes.
