Potential role of Schwann cells in neuropathic pain.

Neuropathic pain (NPP) is a common syndrome associated with most forms of cancer, which poses a serious threat to human health. NPP may persist even after the nociceptive stimulation is […]

DRG afferents that mediate physiologic and pathologic mechanosensation from the distal colon.

The properties of dorsal root ganglia (DRG) neurons that innervate the distal colon are poorly defined, hindering our understanding of their roles in normal physiology and gastrointestinal (GI) disease. Here, […]

TissueGene-C induces long-term analgesic effects through regulation of pain mediators and neuronal sensitization in a rat monoiodoacetate-induced model of osteoarthritis pain.

TissueGene-C (TG-C), a combination of human allogeneic chondrocytes and irradiated GP2-293 cells engineered to overexpress transforming growth factor-β1 (TGF-β1), has been developed as a novel cell-based gene therapy and a […]

Sex-related correspondence between mechanical hypersensitivity and the discharge of medullary pain control neurons in neuropathic rats.

Here we studied whether the sex-related difference in mechanical hypersensitivity induced by neuropathy is associated with the discharge rate of medullary pain control neurons. We performed experiments in male and […]

Sex differences in peripheral immune cell activation: Implications for pain and pain resolution.

Decades of research into chronic pain has deepened our understanding of the cellular mechanisms behind this process. However, a failure to consider the biological variable of sex has limited the […]

Extracellular RNAs-TLR3 signaling contributes to cognitive impairment after chronic neuropathic pain in mice.

Chronic pain is often associated with cognitive decline, which could influence the quality of the patient’s life. Recent studies have suggested that Toll-like receptor 3 (TLR3) is crucial for memory […]

A common neuronal ensemble in nucleus accumbens regulates pain-like behaviour and sleep.

A comorbidity of chronic pain is sleep disturbance. Here, we identify a dual-functional ensemble that regulates both pain-like behaviour induced by chronic constrictive injury or complete Freund’s adjuvant, and sleep […]

A novel role for astrocytic fragmented mitochondria in regulating morphine addiction.

Chronic morphine exposure causes the development of addictive behaviors, accompanied by an increase in neuroinflammation in the central nervous system. While previous researches have shown that astrocytes contribute to brain […]

Menthol excites dural afferent neurons by inhibiting leak K conductance in rats.

Menthol-a natural organic compound-is widely used for relieving various pain conditions including migraine. However, a high dose of menthol reportedly decreases pain thresholds and enhances pain responses. Accordingly, in the […]

Proteomic Analysis of the Amygdala Reveals Dynamic Changes in Glutamate Transporter-1 During Progression of Complete Freund’s Adjuvant-Induced Pain Aversion.

Pain sufferer usually show an aversion to the environment associated with pain, identified as pain aversion. The amygdala, an almond-shaped limbic structure in the medial temporal lobe, exerts a critical […]
