The current knowledge about heat nociception is mainly confined to the thermosensors, including the transient receptor potential cation channel V1 expressed in the nociceptive neurons of dorsal root ganglion (DRG). However, the loss of thermosensors only partially impairs heat nociception, suggesting the existence of undiscovered mechanisms. We found that the loss of an intracellular fibroblast...
G-protein-gated potassium (K+) channels are found throughout the CNS in which they contribute to the inhibitory effects of neurotransmitters and drugs of abuse. Recent studies have implicated G-protein-gated K+ channels in thermal nociception and the analgesic action of morphine and other agents. Because nociception is subject to complex spinal and supraspinal modulation, however, the relevant ...
In healthy individuals, emotions modulate pain and spinal nociception according to a valence linear trend (ie, pain/nociception is highest during negative emotions and lowest during positive emotions). However, emerging evidence suggests that emotional modulation of pain (but not spinal nociception) is disrupted in fibromyalgia and disorders associated with chronic pain risk (eg, major depressi...
Background Experimental osteoarthritis entails neuropathic-like changes in dorsal root ganglia (DRG) neurons. Since glial activation has emerged as a key player in nociception, being reported in numerous models of neuropathic pain, we aimed at evaluating if glial cell activation may also occur in the DRG and spinal cord of rats with osteoarthritis induced by intra-articular injection of collage...
Nociceptin/orphanin FQ (N/OFQ), nocistatin, and prepro-N/OFQ 160-187 (C-peptide) are all derived from the same precursor protein. We examine the pharmacological mechanisms of nocistatin- and C-peptide-induced pronociceptive responses in a novel algogenic-induced nociceptive flexion test in mice. The intraplantar (i.pl.) injection of nocistatin- and C-peptide induced pronociceptive responses in ...
