Camphor Attenuates Hyperalgesia in Neuropathic Pain Models in Mice.

The treatment of neuropathic pain is still a major troublesome clinical problem. The existing therapeutic drugs have limited analgesic effect and obvious adverse reactions, which presents opportunities and challenges for the development of […]

Kinin B and B receptors mediate cancer pain associated with both the tumor and oncology therapy using aromatase inhibitors.

Pain caused by the tumor or aromatase inhibitors (AIs) is a disabling symptom in breast cancer survivors. Their mechanisms are unclear, but pro-algesic and inflammatory mediators seem to be involved. […]

K Channel Prodrugs Reduce Inflammatory and Neuropathic Hypersensitivity, Morphine Induced Hypersensitivity, and Precipitated Withdrawal in Mice.

Previous studies show ATP-sensitive potassium (K) channel openers can reduce hypersensitivity associated with chronic pain models in rodents, and reduce morphine tolerance. Many agonists of K channels are not soluble […]

Spinal Astrocytic MeCP2 Regulates Kir4.1 for the Maintenance of Chronic Hyperalgesia in Neuropathic Pain.

Astrocyte activation in the spinal dorsal horn may play an important role in the development of chronic neuropathic pain, but the mechanisms involved in astrocyte activation and their modulatory effects […]

Duloxetine and Amitriptyline Reduce Neuropathic Pain by Inhibiting Primary Sensory Input to Spinal Dorsal Horn Neurons via α1- and α2-Adrenergic Receptors.

Antidepressants, such as duloxetine and amitriptyline, are effective for treating patients with chronic neuropathic pain. Inhibiting norepinephrine and serotonin transporters at presynaptic terminals raises extracellular concentrations of norepinephrine. The α1- […]

P2X7-NLRP3-Caspase-1 signaling mediates activity-induced muscle pain in male but not female mice.

We developed an animal model of activity-induced muscle pain that is dependent on local macrophage activation and release of interleukin-1β (IL-1β). Activation of purinergic type 2X (P2X) 7 receptors recruits […]

Exosomes-loaded electroconductive nerve dressing for nerve regeneration and pain relief against diabetic peripheral nerve injury.

Over the years, electroconductive hydrogels (ECHs) have been extensively applied for stimulating nerve regeneration and restoring locomotor function after peripheral nerve injury (PNI) with diabetes, given their favorable mechanical and […]

Switching anti-CGRP(R) monoclonal antibodies in multi-assessed non-responder patients and implications for ineffectiveness criteria: A retrospective cohort study.

A pharmacological class effect was initially proposed for monoclonal antibodies against the calcitonin gene related peptide pathway. However, preliminary evidence shows that switching patients who were non-responding to one monoclonal […]

Covalently Binding Adenosine A Receptor Agonist ICBM Irreversibly Reduces Voltage-Gated Ca Currents in Dorsal Root Ganglion Neurons.

Interest has been focused in recent years on the analgesic effects exerted by adenosine and its receptors, A, A, A, and A adenosine receptor (AR) subtypes, in different in vivo […]

Phenelzine-based probes reveal Secernin-3 is involved in thermal nociception.

Chemical platforms that facilitate both the identification and elucidation of new areas for therapeutic development are necessary but lacking. Activity-based protein profiling (ABPP) leverages active site-directed chemical probes as target […]
