mGluR5 from primary sensory neurons promotes opioid-induced hyperalgesia and tolerance by interacting with and potentiating synaptic NMDA receptors.

Aberrant activation of presynaptic NMDA receptors (NMDARs) in the spinal dorsal horn is integral to opioid-induced hyperalgesia and analgesic tolerance. However, the signaling mechanisms responsible for opioid-induced NMDAR hyperactivity remain […]

Parabrachial nucleus activity in nociception and pain in awake mice.

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

Assessment of Pain and Inflammation in Domestic Animals Using Infrared Thermography: A Narrative Review.

Pain assessment in domestic animals has gained importance in recent years due to the recognition of the physiological, behavioral, and endocrine consequences of acute pain on animal production, welfare, and […]

Translation of Experimental Findings from Animal to Human Biology: Identification of Neuronal Mineralocorticoid and Glucocorticoid Receptors in a Sectioned Main Nerve Trunk of the Leg.

The activation of the mineralocorticoid (MR) and glucocorticoid (GR) receptors on peripheral sensory neurons seems to modify pain perception through both direct non-genomic and indirect genomic pathways. These distinct subpopulations […]

GLP-1R agonist liraglutide attenuates pain hypersensitivity by stimulating IL-10 release in a nitroglycerin-induced chronic migraine mouse model.

Glucagon-like peptide-1 receptor (GLP-1R) has been indicated to involve in chronic pain, however, the mechanism by which GLP-1R alleviates the central sensitization of chronic migraine (CM) remains unclear. Treatment with […]

Combination gene delivery reduces spinal cord pathology in rats with peripheral neuropathic pain.

Although peripheral neuropathic pain (NP) is caused by peripheral nerve injury, it is not simply a peripheral nervous system disease. It causes abnormalities in both the central and peripheral nervous […]

Ropivacaine microsphere-loaded electroconductive nerve dressings for long-acting analgesia and functional recovery following diabetic peripheral nerve injury.

In recent years, electroconductive hydrogels (ECHs) have shown great potential in promoting nerve regeneration and motor function recovery following diabetic peripheral nerve injury (PNI), attributed to their similar electrical and […]

The Anti-Arthritic Activity of Diclofenac Lipid-Core Nanocapsules: Stereological Analysis Showing More Protection of Deep Joint Components.

Diclofenac is the most prescribed nonsteroidal anti-inflammatory drug worldwide and is used to relieve pain and inflammation in inflammatory arthritis. Diclofenac is associated with serious adverse effects, even in regular-dose […]

Influence of Inflammatory Pain and Dopamine on Synaptic Transmission in the Mouse ACC.

Dopamine (DA) inhibits excitatory synaptic transmission in the anterior cingulate cortex (ACC), a brain region involved in the sensory and affective processing of pain. However, the DA modulation of inhibitory […]
