Effects of Duloxetine on the Toll-Like Receptor 4 Signaling Pathway in Spinal Dorsal Horn in a Rat Model of Diabetic Neuropathic Pain

摘要

Objective. Although duloxetine has been approved for clinical therapy for diabetic peripheral neuropathic pain, the exact mechanism underlying the anti-allodynic effects in rat models of diabetes mellitus remains obscure. We attempted to identify whether duloxetine exerts anti-allodynic effects via inhibition of the TLR4-Myd88-dependent pathway in diabetic neuropathic pain (DNP) rats.
