Remifentanil is an ultra-short-acting mu-opioid receptor agonist, which is widely used in general anesthesia. However, comparing with other opioids, remifentanil often induces hyperalgesia. Accumulating evidence suggests that the transient receptor potential (TRP) channels and glial cells activation were involved in the development of neuropathic pain and hyperalgesia. However, whether the TRP channels and glial cells contribute to remifentanil-induced hyperalgesia is still unknown. In this study, we used the hot-plate and Von Frey tests to evaluate the thermal and mechanical hyperalgesia. Protein expressions of TRPV1 and protein kinase C (PKC) in dorsal root ganglion were assayed by western blotting and mRNA level of Trpv1, Trpa1, Trpv4, and Trpm8 were assayed by real-time PCR. TNF-alpha, IL-1 beta, and IL-6 levels in spinal cord were measured by ELISA. Immunofluorescence assay was applied to analyze the activation of astrocyte in spinal cord. Continuing infusion of remifentanil induced thermal hyperalgesia and mechanical allodynia, which were accompanied by upregulation of TRPV1 and PKC protein in dorsal root ganglion. Moreover, remifentanil also increased the TNF-alpha, IL-1 beta, and IL-6 levels and activates the astrocyte in spinal cord. Our findings suggested that TRPV1 is involved in the TRPV1-PKC signaling pathway, which contributes to the persistence of remifentanil-induced postoperative hyperalgesia. In addition, the spinal astrocyte activation and inflammatory reaction are involved in the remifentanil-induced postoperative hyperalgesia.
