Cytokines, specifically tumor necrosis factor (TNF) and interleukins (IL), are key mediators in the initiation and maintenance of chronic pain states. Sensory neurons expressing receptors for cytokines like TNF, IL-1, and IL-6 are implicated in peripheral sensitization, contributing to increased signaling of painful sensations. The potential of targeting TNF and IL for therapeutic intervention in chronic pain states is the focus of this review, with preclinical and clinical evidence supporting the use of TNF and IL modulators for pain management. The physiological and pathological roles of TNF in neuropathic pain is complex. Experimental evidence highlights the effectiveness of TNF modulation in mitigating pain symptoms in animal models and displays promising outcomes of clinical trials with TNF inhibitors, such as infliximab and etanercept. ILs, a diverse group of cytokines, including IL-1, IL-6, and IL-17, are discussed for their contributions to chronic pain through inflammation and peripheral sensitization. Specific IL modulators, such as secukinumab and tocilizumab, have shown potential in managing chronic neuropathic pain, as demonstrated in various studies and clinical trials. The pharmacokinetics, safety profiles, and challenges associated with TNF and IL modulators highlight the need for cautious medication monitoring in clinical practice. Comparative evaluations have revealed distinct efficacy and safety profiles among different cytokine modulators, emphasizing the need for personalized approaches based on the specific underlying causes of pain. Further research is necessary to elucidate the intricate mechanisms by which cytokines contribute to chronic pain, as well as to understand why they may affect pain differently in various contexts.
