Neuropathic pain is associated with diverse etiologies, including sciatica, diabetes, and the use of chemotherapeutic agents. Despite the varied origins, mitochondrial dysfunction, oxidative stress, and inflammatory cytokines are recognized as key contributing factors in both the initiation and maintenance of neuropathic pain. The effects of the mitochondrial-derived peptide humanin on neuropathic pain, however, remain unclear, despite its demonstrated influence on these mechanisms in numerous disease models.
