Intraganglionic reactive oxygen species mediate inflammatory pain and hyperalgesia through TRPA1 in the rat.

Reactive oxygen species (ROS) are generated in nociceptive pathways in response to inflammation and injury. ROS are accumulated within the sensory ganglia following peripheral inflammation, but the functional role of […]

Dysfunction of inhibitory interneurons contributes to synaptic plasticity via GABABR-pNR2B signaling in a chronic migraine rat model.

According to our previous study, the loss of inhibitory interneuron function contributes to central sensitization in chronic migraine (CM). Synaptic plasticity is a vital basis for the occurrence of central […]

Mu opioid receptor expressing neurons in the rostral ventromedial medulla are the source of mechanical hypersensitivity induced by repeated restraint stress.

Repeated exposure to psychophysical stress often causes an increase in sensitivity and response to pain. This phenomenon is commonly called stress-induced hyperalgesia (SIH). Although psychophysical stress is a well-known risk […]

Opposing effects of 5-HT1A receptor agonist buspirone on supraspinal abdominal pain transmission in normal and visceral hypersensitive rats.

The serotonergic 5-HT1A receptors are implicated in the central mechanisms of visceral pain, but their role in these processes is controversial. Considering existing evidences for organic inflammation-triggered neuroplastic changes in […]

Conserved transcriptional programming across sex and species after peripheral nerve injury predicts treatments for neuropathic pain.

Chronic pain is a devastating problem affecting 1 in 5 individuals around the globe, with neuropathic pain the most debilitating and poorly treated type of chronic pain. Advances in transcriptomics […]

Design, synthesis, and analgesia evaluation of novel Transient Receptor Potential Vanilloid 1 (TRPV1) agonists modified from Cannabidiol (CBD).

Pain-relief is a long-term research hotspot with huge demand in clinical treatment. The analgesics currently used have several side effects, such as being addictive and causing gastrointestinal bleeding. Therefore, new […]

Is there an association between serum soluble interleukin-2 receptor levels and syndrome severity in persistent Complex Regional Pain Syndrome?

A potentially useful biomarker for Complex Regional Pain Syndrome (CRPS) is the serum soluble interleukin-2 receptor (sIL-2R) level, which is a marker for T-cell activation. Elevated serum sIL-2R levels have […]

Understanding the effects of mesenchymal stromal cell therapy for treating osteoarthritis using an in vitro co-culture model.

Osteoarthritis (OA) is a leading cause of chronic pain and disability, for which there is no cure. Mesenchymal stromal cells (MSCs) have been used in clinical trials for treating OA […]

Non-Coding RNAs Regulate Spinal Cord Injury-Related Neuropathic Pain via Neuroinflammation.

Secondary chronic neuropathic pain (NP) in addition to sensory, motor, or autonomic dysfunction can significantly reduce quality of life after spinal cord injury (SCI). The mechanisms of SCI-related NP have […]
