Transient depletion of macrophages alters local inflammatory response at the site of disc herniation in a transgenic mouse model.

Macrophages are abundantly detected at sites of disc herniation, however, their function in the disease progression is unclear. We aim to investigate the functions of macrophages in acute disc herniation […]

Schwann cell-derived CXCL2 contributes to cancer pain by modulating macrophage infiltration in a mouse breast cancer model.

Pain is one of the most severe complications affecting the quality of life of cancer patients. Although substantial progress has been made in the diagnosis and treatment of cancer, the […]

Coordinated activity of a central pathway drives associative opioid analgesic tolerance.

Opioid analgesic tolerance, a root cause of opioid overdose and misuse, can develop through an associative learning. Despite intensive research, the locus and central pathway subserving the associative opioid analgesic […]

The C. elegans Innexin INX-20 Regulates Nociceptive Behavioral Sensitivity.

Organisms rely on chemical cues in their environment to indicate the presence or absence of food, reproductive partners, predators or other harmful stimuli. In the nematode Caenorhabditis elegans, the bilaterally […]

Phosphate NIMA-Related Kinase 2-Dependent Epigenetic Pathways in Dorsal Root Ganglion Neurons Mediates Paclitaxel-Induced Neuropathic Pain.

The microtubule-stabilizing drug paclitaxel (PTX) is an important chemotherapeutic agent for cancer treatment and causes peripheral neuropathy as a common side effect that substantially impacts the functional status and quality […]

Ubiquitin‑specific peptidase 53 promotes chronic constriction injury‑induced neuropathic pain through the RhoA/ROCK pathway.

Neuropathic pain is associated with nervous system injury and the production of pro‑inflammatory factors. Critical functions for ubiquitin‑specific peptidase 53 (USP53) have been demonstrated in various diseases. However, the role […]

The role of Ectopic P granules protein 5 homolog (EPG5) in DHPG-induced pain sensitization in mice.

Nociplastic pain is a severe health problem, while its mechanisms are still unclear. (R, S)-3,5-Dihydroxyphenylglycine (DHPG) is a group I metabotropic glutamate receptor (mGluR) agonist that can cause central sensitization, […]

Epidermal SIRT1 and BDNF modulate mechanical allodynia in mouse models of diabetic neuropathy.

Diabetic neuropathy (DN) is a debilitating disorder characterized by mechanical allodynia and sensory loss. It has traditionally been considered a small-fiber neuropathy, defined by the loss of free nerve endings […]

Endogenous inflammatory mediators produced by injury activate TRPV1 and TRPA1 nociceptors to induce sexually dimorphic cold pain that is dependent on TRPM8 and GFRα3.

The detection of environmental temperatures is critical for survival, yet inappropriate responses to thermal stimuli can have a negative impact on overall health. The physiological effect of cold is distinct […]

Electrical Stimulation of the Auricular Branch Vagus Nerve Using Random and Alternating Frequencies Triggers a Rapid Onset and Pronounced Antihyperalgesia via Peripheral Annexin A1-Formyl Peptide Receptor 2/ALX Pathway in a Mouse Model of Persistent Inflammatory Pain.

This study evaluated the antihyperalgesic and anti-inflammatory effects of percutaneous vagus nerve electrical stimulation (pVNS) by comparing the effects of alternating and random frequencies in an animal model of persistent […]
