Shared and independent roles of CGRP and PACAP in migraine pathophysiology.

The neuropeptides calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating polypeptide (PACAP) have emerged as mediators of migraine pathogenesis. Both are vasodilatory peptides that can cause migraine-like attacks when infused […]

Factors affecting the prevalence, severity, and characteristics of ocular surface pain.

Ocular surface pain has been traditionally lumped under the umbrella term “dry eye” (DE) but is now understood as its own entity and can occur in the absence or presence […]

Sex differences in the role of parabrachial in nociception and pain in awake mice.

The parabrachial nuclear complex is a nexus for aversion, and for the sensory and affective components of pain perception. We have previously shown that, during chronic pain, parabrachial neurons in […]

An Observational Study on Chronic Pain Biomarkers in Fibromyalgia and Osteoarthritis Patients: Which Role for Mu Opioid Receptor’s Expression on NK Cells?

The evaluation of chronic pain is challenging because of the lack of specific biomarkers. We identified the Mu opioid receptor-positive (Mu+) B cell percentage of expression, named Mu-Lympho-Marker (MLM), as […]

Novel Insights into the Role of Keratinocytes-Expressed TRPV3 in the Skin.

TRPV3 is a non-selective cation channel that is highly expressed in keratinocytes in the skin. Traditionally, keratinocytes-expressed TRPV3 is involved in multiple physiological and pathological functions of the skin, such […]

Chemokine CCL7 mediates trigeminal neuropathic pain via CCR2/CCR3-ERK pathway in the trigeminal ganglion of mice.

Chemokine-mediated neuroinflammation plays an important role in the pathogenesis of neuropathic pain. The chemokine CC motif ligand 7 (CCL7) and its receptor CCR2 have been reported to contribute to neuropathic […]

Spinal dopaminergic D-and D-like receptors have a sex-dependent effect in an experimental model of fibromyalgia.

There is evidence about the importance of sex in pain. The purpose of this study was to investigate the effect of sex in the antiallodynic activity of spinal dopamine D-and […]

Itch receptor MRGPRX4 interacts with the receptor activity-modifying proteins (RAMPs).

Cholestatic itch is a severe and debilitating symptom in liver diseases with limited treatment options. The class A G protein-coupled receptor (GPCR) Mas-related GPCR subtype X4 (MRGPRX4) has been identified […]

Suberoylanilide Hydroxamic Acid Ameliorates Pain Sensitization in Central Neuropathic Pain After Spinal Cord Injury via the HDAC5/NEDD4/SCN9A Axis.

Pain sensitization in spinal cord injury (SCI)-induced central neuropathic pain has been a research target. Additionally, suberoylanilide hydroxamic acid (SAHA) has been reported to protect against pain hypersensitivity in central […]

Prevalence of chronic pain in hemodialysis patients and its correlation with C-reactive protein: a cross-sectional study.

End-stage renal disease (ESRD) is a common chronic disease worldwide that requires hemodialysis. Patients may face chronic pain and poor quality of life. Therefore, a better understanding of these variables […]
