Analgesia is an important effect of volatile anaesthetics, for which the spinal cord is a critical neural target. However, how supraspinal mechanisms modulate analgesic potency of volatile anaesthetics is not clear. We investigated the contribution of the central amygdala (CeA) to the analgesic effects of isoflurane and sevoflurane. ⋯ The analgesic potencies of volatile anaesthetics are partially mediated by modulation of NALCN in CeAGABA neurones.

Nerve injury-induced changes in gene expression in the dorsal root ganglion (DRG) contribute to the genesis of neuropathic pain. SYNCRIP, an RNA-binding protein, is critical for the stabilisation of gene expression. Whether SYNCRIP participates in nerve injury-induced alterations in DRG gene expression and nociceptive hypersensitivity is unknown. ⋯ SYNCRIP contributes to the induction and maintenance of neuropathic pain likely through stabilising expression of CCR2 in injured DRG. SYNCRIP may be a potential target for treating this disorder.
