Regular walking exercise prior to knee osteoarthritis reduces joint pain in an animal model.

We investigated the effect of regular walking exercise prior to knee osteoarthritis (OA) on pain and synovitis in a rat monoiodoacetic acid (MIA)-induced knee OA model. Seventy-one male Wistar rats […]

PACAP/PAC1-R activation contributes to hyperalgesia in 6-OHDA-induced Parkinson’s disease model rats via promoting excitatory synaptic transmission of spinal dorsal horn neurons.

Pain is a common annoying non-motor symptom in Parkinson’s disease (PD) that causes distress to patients. Treatment for PD pain remains a big challenge, as its underlying mechanisms are elusive. […]

Mechanisms of initiation of cortical spreading depression.

There is increasing evidence from human and animal studies that cortical spreading depression (CSD) is the neurophysiological correlate of migraine aura and a trigger of migraine pain mechanisms. The mechanisms […]

The Anterior Insula and its Projection to the Prelimbic Cortex are Involved in the Regulation of 5-HT-Induced Itch.

Itch is an unpleasant sensation that urges people and animals to scratch. Neuroimaging studies on itch have yielded extensive correlations with diverse cortical and subcortical regions, including the insular lobe. […]

NPRC deletion mitigated atherosclerosis by inhibiting oxidative stress, inflammation and apoptosis in ApoE knockout mice.

Previous studies suggested a beneficial effect of natriuretic peptides in animal models of cardiovascular disease, but the role of natriuretic peptide receptor C (NPRC) in the pathogenesis of atherosclerosis (AS) […]

Eosinophil Phenotypes are Functionally Regulated by Resolvin D2 During Allergic Lung Inflammation.

Eosinophils (Eos) reside in multiple organs during homeostasis and respond rapidly to an inflammatory challenge. Although Eos share chemical staining properties, they also demonstrate phenotypic and functional plasticity that is […]

The clinically-approved compounds, pramipexole and dexpramipexole, reverse chronic allodynia from sciatic nerve damage in mice, and alter IL-1β and IL-10 expression from immune cell culture.

During the onset of neuropathic pain from a variety of etiologies, nociceptors become hypersensitized, releasing neurotransmitters and other factors from centrally-projecting nerve terminals within the dorsal spinal cord. Consequently, glial […]

Rutaecarpine alleviates migraine in nitroglycerin-induced mice by regulating PTEN/PGK1 signaling pathway to activate NRF2 antioxidant system.

Due to its widespread prevalence, migraine is a common neurovascular condition that has a major impact on people’s health and quality of life. Rutaecarpine (RUT) is one of the main […]

Establishing a new model of cancer neuropathic pain in rats.

To guide the treatment of malignant neuropathic pain (MNP) in clinical practice, by inoculating MADB-106 breast cancer cells into the right L4 nerve root in Sprague-Dawley rats, a rat model […]

Hydralazine Promotes Central Nervous System Recovery after Spinal Cord Injury by Suppressing Oxidative Stress and Inflammation through Macrophage Regulation.

This study aims to investigate the effects of hydralazine on inflammation induced by spinal cord injury (SCI) in the central nervous system (CNS) and its mechanism in promoting the structural […]
