Descending serotonergic modulation from rostral ventromedial medulla to spinal trigeminal nucleus is involved in experimental occlusal interference-induced chronic orofacial hyperalgesia.

Dental treatment associated with unadaptable occlusal alteration can cause chronic primary myofascial orofacial pain. The serotonin (5-HT) pathway from the rostral ventromedial medulla (RVM) exerts descending modulation on nociceptive transmission […]

TRPV1 inhibition overcomes cisplatin resistance by blocking autophagy-mediated hyperactivation of EGFR signaling pathway.

Cisplatin resistance along with chemotherapy-induced neuropathic pain is an important cause of treatment failure for many cancer types and represents an unmet clinical need. Therefore, future studies should provide evidence […]

Sustained and potent analgesia with negligible side effects enabled by adaptive individualized granular stimulation in rat brainstem.

To clarify if an adaptive current stimulation protocol, in which current amplitude is modulated during continuous stimulation, provides better efficacy than constant current stimulation protocol with respect to analgesia caused […]

SARS-CoV-2 airway infection results in the development of somatosensory abnormalities in a hamster model.

Although largely confined to the airways, SARS-CoV-2 infection has been associated with sensory abnormalities that manifest in both acute and chronic phenotypes. To gain insight on the molecular basis of […]

Foramen lacerum impingement of trigeminal nerve root (FLIT) as a rodent model for trigeminal neuralgia.

Trigeminal neuralgia (TN) is a classical neuralgic pain condition with distinct clinical characteristics. Modeling TN in rodents proves challenging. Recently, we found that a foramen in rodent skull base, the […]

CXCL13 contributes to chronic pain of a mouse model of CRPS-I via CXCR5-mediated NF-κB activation and pro-inflammatory cytokine production in spinal cord dorsal horn.

Complex regional pain syndrome type-I (CRPS-I) causes excruciating pain that affect patients’ life quality. However, the mechanisms underlying CRPS-I are incompletely understood, which hampers the development of target specific therapeutics.

Trace amine-associated receptor 1 regulation of Kv1.4 channels in trigeminal ganglion neurons contributes to nociceptive behaviors.

Trace amines, such as tyramine, are endogenous amino acid metabolites that have been hypothesized to promote headache. However, the underlying cellular and molecular mechanisms remain unknown.

Time-dependent photobiomodulation management of neuropathic pain induced by spinal cord injury in male rats.

Neuropathic pain (NP) following spinal cord injury (SCI) often lasts for a long time and causes a range of problems that reduce the quality of life. Current treatments are not […]

Intrathecal Administration of Conditioned Serum from Different Species Resolves Chemotherapy-Induced Neuropathic Pain in Mice via Secretory Exosomes.

Chemotherapy-induced peripheral neuropathy (CIPN) is the most prevalent neurological complication of chemotherapy for cancer, and has limited effective treatment options. Autologous conditioned serum (ACS) is an effective biologic therapy used […]

Structure-based virtual screening for discovery of paederosidic acid from Paederia scandens as novel P2YR antagonist.

The activation of P2Y receptor (P2YR) promotes osteoclast formation and causes neuropathic pain, exhibiting possible link to osteoarthritis (OA). Given lack of P2YR antagonist, the present study aims to search […]
