Effects of NADPH Oxidase Isoform-2 (NOX2) Inhibition on Behavioral Responses and Neuroinflammation in a Mouse Model of Neuropathic Pain.

NADPH oxidase isoform-2 (NOX2) has been implicated in the pathophysiology of neuropathic pain (NP), mostly through the modulation of neuroinflammation. Since it is also accepted that some neuroimmune mechanisms underlying […]

The Constitutive Activity of Spinal 5-HT Receptors Contributes to Diabetic Neuropathic Pain in Rats.

Diabetic neuropathy is often associated with chronic pain. Serotonin type 6 (5-HT) receptor ligands, particularly inverse agonists, have strong analgesic potential and may be new candidates for treating diabetic neuropathic […]

Identification of Lipid Biomarkers for Chronic Joint Pain Associated with Different Joint Diseases.

Lipids, especially lysophosphatidylcholine LPC16:0, have been shown to be involved in chronic joint pain through the activation of acid-sensing ion channels (ASIC3). The aim of the present study was to […]

Ultramicronized -Palmitoylethanolamine Regulates Mast Cell-Astrocyte Crosstalk: A New Potential Mechanism Underlying the Inhibition of Morphine Tolerance.

Persistent pain can be managed with opioids, but their use is limited by the onset of tolerance. Ultramicronized -palmitoylethanolamine (PEA) in vivo delays morphine tolerance with mechanisms that are still […]

Hydrogen Sulfide Downregulates Oncostatin M Expression via PI3K/Akt/NF-κB Signaling Processes in Neutrophil-like Differentiated HL-60 Cells.

The cytokine oncostatin M (OSM) is regarded as a critical mediator in various inflammatory responses. While the gaseous signaling molecule hydrogen sulfide (HS) plays a role in a variety of […]

Analgesic Effect of Perineural Injection of BoNT/A on Neuropathic Pain Induced by Chronic Constriction Injury of Sciatic Nerve in Rats.

This study was designed to investigate the analgesic effect of perineural injection of BoNT/A on neuropathic pain induced by sciatic nerve chronic constriction injury (CCI) and possible mechanisms. SD rats […]

An analgesic pathway from parvocellular oxytocin neurons to the periaqueductal gray in rats.

The hypothalamic neuropeptide oxytocin (OT) exerts prominent analgesic effects via central and peripheral action. However, the precise analgesic pathways recruited by OT are largely elusive. Here we discovered a subset […]

Gut microbiota affects pancreatic fibrotic progression through immune modulation in chronic pancreatitis.

Chronic pancreatitis (CP) is characterized by chronic progressive pancreatic inflammation, which leads to the permanent damage of exocrine and endocrine cells. CP causes irreversible morphological and functional changes, and the […]

NAN-190, a 5-HT1A antagonist, alleviates inflammatory pain by targeting Nav1.7 sodium channels.

In the present study, NAN-190 [1-(2-methoxyphenyl)-4-[4-(2-phthalimido) butyl] piperazine] was identified as a Nav1.7 blocker. In the meantime, the compound could alleviate the Complete Freund’s Adjuvant (CFA)-induced inflammatory pain. To understand […]

ATF5 Attenuates the Secretion of Pro-Inflammatory Cytokines in Activated Microglia.

The highly dynamic changes in microglia necessary to achieve a rapid neuroinflammatory response require a supply of energy from mitochondrial respiration, which leads to the accumulation of unfolded mitochondrial proteins. […]
