Macrophage epigenetic memories of early life injury drive neonatal nociceptive priming.

The developing peripheral nervous and immune systems are functionally distinct from adults. These systems are vulnerable to effects of early life injury which can influence outcomes related to nociception following […]

Chronic morphine induces adaptations in opioid receptor signaling in a thalamo-cortico-striatal circuit that are projection-dependent, sex-specific and regulated by mu opioid receptor phosphorylation.

Chronic opioid exposure induces tolerance to the pain-relieving effects of opioids but sensitization to some other effects. While the occurrence of these adaptations is well-understood, the underlying cellular mechanisms are […]

The Role of IL-6 and TMEM100 in Lumbar Discogenic Pain and the Mechanism of the Glycine-Serine-Threonine Metabolic Axis: A Metabolomic and Molecular Biology Study.

It is well established that discogenic low back pain (DLBP) is often caused by the inflammatory response during intervertebral disc degeneration (IDD). However, it remains unclear how inflammatory mediators such […]

CYP1B1-derived epoxides modulate the TRPA1 channel in chronic pain.

Pain is often debilitating, and current treatments are neither universally efficacious nor without risks. Transient receptor potential (TRP) ion channels offer alternative targets for pain relief, but little is known […]

Bispecific sigma-1 receptor antagonism and mu-opioid receptor partial agonism: WLB-73502, an analgesic with improved efficacy and safety profile compared to strong opioids.

Opioids are the most effective painkillers, but their benefit-risk balance often hinder their therapeutic use. WLB-73502 is a dual, bispecific compound that binds sigma-1 (S1R) and mu-opioid (MOR) receptors. WLB-73502 […]

Satellite glial cells drive the transition from acute to chronic pain in a rat model of hyperalgesic priming.

Chronic pain is one of the most common clinical syndromes affecting patients’ quality of life. Regulating the transition from acute to chronic pain is a novel therapeutic strategy for chronic […]

Modulating the activity of human nociceptors with a SCN10A promoter-specific viral vector tool.

Despite the high prevalence of chronic pain as a disease in our society, there is a lack of effective treatment options for patients living with this condition. Gene therapies using […]

P2X7 receptor-activated microglia in cortex is critical for sleep disorder under neuropathic pain.

Neuropathic pain (NP) is associated with sleep disturbances, which may substantially influence the quality of life. Clinical and animal studies demonstrated that neurotransmitter is one of the main contributors to […]

BRD9 Inhibition Attenuates Matrix Degradation and Pyroptosis in Nucleus Pulposus by Modulating the NOX1/ROS/NF-κB axis.

Intervertebral disc degeneration (IDD) is considered to be the leading cause of low back pain (LBP). The progression of IDD is closely related to the inflammatory microenvironment, which results in […]

Blocking SphK/S1P/S1PR1 axis Signaling Pathway Alleviates Remifentanil- induced Hyperalgesia in Rats.

Recent research shows a correlation between altered sphingolipid metabolism and nociceptive processing. Activation of the sphingosine-1-phosphate receptor 1 subtype (S1PR1) by its ligand, sphingosine-1-phosphate (S1P), causes neuropathic pain. However, its […]
