ABSTRACT
Aim To explore the effect of GSK-3β (glycogen synthase kinase-3 beta) inhibitor TDZD-8 on the neuropathic pain induced by side effects of chemotherapeutic drug oxaliplatin and the underlying mechanism. Methods The rat model of oxaliplatin-induced neuropathic pain was established by intraperitoneal injection of oxaliplatin for five consecutive days; the anti-nociception effect was detected by intrathecal injection of TDZD-8. The spontaneous flinches and mechanical pain threshold were used to detect the changes of pain behavior of rats; immunofluorescence and Western blot analysis were used to detect the changes of spinal inflammation and protein levels of rats. Results Intrathecally injection of TDZD-8 significantly alleviated oxaliplatin induced hyperalgesia in rats. TDZD-8 injection obviously inhibited the activation spinal microglia and the inflammatory reaction. TDZD-8 administration significantly inhibited GSK-3β activation. Conclusion TDZD-8 blocks GSK-3β activation, decreases NLRP3 (NOD-, LRR-, and pyrin domain-containing protein 3) inflammasome mediated spinal inflammation and alleviates neuropathic pain.
