Acetaldehyde via CGRP receptor and TRPA1 in Schwann cells mediates ethanol-evoked periorbital mechanical allodynia in mice: relevance for migraine.

Ingestion of alcoholic beverages is a known trigger of migraine attacks. However, whether and how ethanol exerts its pro-migraine action remains poorly known. Ethanol stimulates the transient receptor potential vanilloid […]

Periaqueductal grey and spinal cord pathology contribute to pain in Parkinson’s disease.

Pain is a key non-motor feature of Parkinson’s disease (PD) that significantly impacts on life quality. The mechanisms underlying chronic pain in PD are poorly understood, hence the lack of […]

Validation of σ R/TMEM97 as a neuropathic pain target: Specificity, human expression and mechanism of action.

The Sigma 2 receptor (σ R) was described pharmacologically more than three decades ago, but its molecular identity remained obscure until recently when it was identified as transmembrane protein 97 […]

PX and P2Y receptor antagonists reduce inflammation in ATP-induced microglia.

P2 receptors have been implicated in the release of neurotransmitter and pro-inflammatory cytokines due to their response to neuro-excitatory substances in the microglia. The P2X4, P2X7 and P2Y12 receptors are […]

βγ G-proteins, but not regulators of G-protein signaling 4, modulate opioid-induced respiratory rate depression.

Opioid medications are the mainstay of pain management but present substantial side-effects such as respiratory depression which can be lethal with overdose. Most opioid drugs, such as fentanyl, act on […]

Chronic corticosterone exposure evokes itch hypersensitivity and sexual dysfunction in male rats: relationship between the two distinct gastrin-releasing peptide systems in the spinal cord.

In today’s society, people are subjected to many social stressors, and excessive chronic stress causes functional disruption of the neuroendocrine system and many diseases. Although the exacerbation of atopic dermatitis […]

DHX9/DNA-tandem repeat-dependent downregulation of ciRNA-Fmn1 in the dorsal horn is required for neuropathic pain.

Circular RNAs (ciRNAs) are emerging as new players in the regulation of gene expression. However, how ciRNAs are involved in neuropathic pain is poorly understood. Here, we identify the nervous-tissue-specific […]

The natural sequence in which subclinically inflamed joint tissues subside or progress to rheumatoid arthritis: a study on serial MRIs in the TREAT EARLIER trial.

Clinical arthritis is the hallmark of rheumatoid arthritis (RA), yet the natural trajectory in which arthritis develops at tissue-level remains elusive. We hypothesized that subclinical inflammation in different joint tissues […]

Signs and symptoms of pediatric complex regional pain syndrome – type 1: A retrospective cohort study.

Complex regional pain syndrome (CRPS) presents with an array of symptoms that can vary from child to child, making it difficult to diagnose and differentiate from other pain conditions such […]
