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 […]

Effectiveness of exercise interventions in animal models of multiple sclerosis.

Multiple sclerosis (MS) is associated with an impaired immune system that severely affects the spinal cord and brain, and which is marked by progressive inflammatory demyelination. Patients with MS may […]

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 […]

Lupeol alleviates atopic dermatitis-like skin inflammation in 2,4-dinitrochlorobenzene/Dermatophagoides farinae extract-induced mice.

Atopic dermatitis (AD) is a chronic inflammatory skin disease that affects from children to adults widely, presenting symptoms such as pruritus, erythema, scaling, and dryness. Lupeol, a pentacyclic triterpenoid, has […]

Design, synthesis, and anti-inflammatory activity characterization of novel brain-permeable HDAC6 inhibitors.

Targeting histone deacetylase 6 (HDAC6) has emerged as a promising therapeutic approach for anti-inflammation and related biological pathways, including inflammatory events associated with the brain. In this study, in order […]

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 […]
