A Critical Involvement of Glutamatergic Neurons in the Anterior Insular Cortex for Subdiaphragmatic Vagotomy-induced Analgesia.

Subdiaphragmatic vagotomy (SDV) is known to produce analgesic effect in various pain conditions including not only visceral pain but also somatic pain. We aimed to determine brain mechanisms by which […]

A Gain-of-function Mutation in the Gating Domain of ITPR1 Impairs Motor Movement and Increases Thermal and Mechanical Sensitivity.

Inositol 1,4,5-trisphosphate receptor type 1 (ITPR1) is an intracellular Ca release channel important for a number of fundamental cellular functions. Consistent with its critical physiological significance, mutations in ITPR1 are […]

Folic acid relieves bone cancer pain by downregulating P2X2/3 receptors in rats.

Bone cancer pain (BCP) remains a clinical challenge due to the limited and side effects of therapeutic methods. Folic acid has been known as an FDA approved dietary supplement and […]

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 […]

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 […]

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.
