Triptolide is a potent immunosuppressive drug capable of inhibiting T cell activation and proliferation. Recent studies show that T cells play an important role in neuropathic pain following nerve injury in rats. In this study, we investigated the effect of triptolide on T cell activation and development of neuropathic pain. ⋯ In the present study, we demonstrated the suppressive effect of triptolide on the development of neuropathic pain. Therefore, triptolide could be a promising immunosuppressive agent in the treatment of neuropathic pain. Further studies are required to examine the safety of intrathecal triptolide for clinical application.
