5-Alkoxy-1-aryl-3-polyfluoroalkylpyrazoles with Antinociceptive Activity: Partial Agonists of TRPV1 Ion Channels.

Chemoselective O-alkylation of 1-aryl-3-polyfluoroalkylpyrazol-5-oles under basic conditions resulted in a series of 5-alkoxypyrazoles (26 derivatives). They were showed to have an acceptable ADME profile (in silico). In experiments in vivo […]

Electrophysiological characterization of a Ca3.1 calcium channel mutation linked to trigeminal neuralgia.

Trigeminal neuralgia is a rare and debilitating disorder that affects one or more branches of the trigeminal nerve, leading to severe pain attacks and a poor quality of life. It […]

Melatonin attenuated chronic visceral pain by reducing Na1.8 expression and nociceptive neuronal sensitization.

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder, and its specific pathogenesis is still unclear. We have previously reported that TTX-resistant (TTX-R) sodium channels in colon-specific dorsal root […]

Sex differences in the role of parabrachial in nociception and pain in awake mice.

The parabrachial nuclear complex is a nexus for aversion, and for the sensory and affective components of pain perception. We have previously shown that, during chronic pain, parabrachial neurons in […]

Systematic identification of potential key microRNAs and circRNAs in the dorsal root ganglia of mice with sciatic nerve injury.

Neuropathic pain (NeP) is a pathological condition arising from a lesion or disease affecting the somatosensory system. Accumulating evidence has shown that circular RNAs (circRNAs) exert critical functions in neurodegenerative […]

Chemokine CCL7 mediates trigeminal neuropathic pain via CCR2/CCR3-ERK pathway in the trigeminal ganglion of mice.

Chemokine-mediated neuroinflammation plays an important role in the pathogenesis of neuropathic pain. The chemokine CC motif ligand 7 (CCL7) and its receptor CCR2 have been reported to contribute to neuropathic […]

Spinal dopaminergic D-and D-like receptors have a sex-dependent effect in an experimental model of fibromyalgia.

There is evidence about the importance of sex in pain. The purpose of this study was to investigate the effect of sex in the antiallodynic activity of spinal dopamine D-and […]

Itch receptor MRGPRX4 interacts with the receptor activity-modifying proteins (RAMPs).

Cholestatic itch is a severe and debilitating symptom in liver diseases with limited treatment options. The class A G protein-coupled receptor (GPCR) Mas-related GPCR subtype X4 (MRGPRX4) has been identified […]

Suberoylanilide Hydroxamic Acid Ameliorates Pain Sensitization in Central Neuropathic Pain After Spinal Cord Injury via the HDAC5/NEDD4/SCN9A Axis.

Pain sensitization in spinal cord injury (SCI)-induced central neuropathic pain has been a research target. Additionally, suberoylanilide hydroxamic acid (SAHA) has been reported to protect against pain hypersensitivity in central […]

Single-Soma Deep RNA sequencing of Human DRG Neurons Reveals Novel Molecular and Cellular Mechanisms Underlying Somatosensation.

The versatility of somatosensation arises from heterogenous human dorsal root ganglion (DRG) neurons. The critical information to decipher their functions, i.e., the soma transcriptome, is lacking due to technical difficulties. […]
