Gut instinct: Sex differences in the gut microbiome are associated with changes in adolescent nociception following maternal separation in rats.

Adolescent chronic pain is a growing public health epidemic. Our understanding of its etiology is limited; however, several factors can increase susceptibility, often developing in response to an acute pain […]

Pharmacological and Physicochemical Properties Optimization for Dual-Target Dopamine D (DR) and μ-Opioid (MOR) Receptor Ligands as Potentially Safer Analgesics.

A new generation of dual-target μ opioid receptor (MOR) agonist/dopamine D receptor (DR) antagonist/partial agonists with optimized physicochemical properties was designed and synthesized. Combining in vitro cell-based on-target/off-target affinity screening, […]

Urolithin A alleviates neuropathic pain and activates mitophagy.

Neuropathic pain (NP) occurs frequently in the general population and has a negative impact on the quality of life. There is no effective therapy available yet owing to the complex […]

Photobiomodulation reduces neuropathic pain after spinal cord injury by downregulating CXCL10 expression.

Many studies have recently highlighted the role of photobiomodulation (PBM) in neuropathic pain (NP) relief after spinal cord injury (SCI), suggesting that it may be an effective way to relieve […]

PPARα and PPARγ are expressed in midbrain dopamine neurons and modulate dopamine- and cannabinoid-mediated behavior in mice.

Peroxisome proliferator-activated receptors (PPARs) are a family of nuclear receptors that regulate gene expression. Δ-tetrahydrocannabinol (Δ-THC) is a PPARγ agonist and some endocannabinoids are natural activators of PPARα and PPARγ. […]

Preclinical characterization of the efficacy and safety of biologic N-001 as a novel pain analgesic for post-operative acute pain treatment.

Inhibition of actin remodeling in nerves modulates action potential propagation and therefore could be used to treat acute pain. N-001 is a novel protein analgesic engineered from several C. Botulinum […]

Soluble Nogo-Receptor-Fc decoy (AXER-204) in patients with chronic cervical spinal cord injury in the USA: a first-in-human and randomised clinical trial.

Spinal cord injury (SCI) causes neural disconnection and persistent neurological deficits, so axon sprouting and plasticity might promote recovery. Soluble Nogo-Receptor-Fc decoy (AXER-204) blocks inhibitors of axon growth and promotes […]

SIX1 induced HULC modulates neuropathic pain and Schwann cell Oxidative stress after sciatic nerve injury.

Neuropathic pain is a severe and debilitating condition caused by damage to the peripheral nerve or central nervous system. Although several mechanisms have been identified, the underlying pathophysiology of neuropathic […]

Anti-proliferative and anti-inflammatory effects of the application of baclofen cream, a GABA receptor agonist, on skin inflammation in mice.

Previous studies have demonstrated the role of γ-aminobutyric acid type B (GABA) receptors in skin-related conditions and pain. However, most studies have focused on the main effects of GABA on […]

Pain and itch processing in aged mice.

Most reports agree that aging negatively impacts pain processing and that the prevalence of chronic pain increases significantly with age. To improve current therapies, it is critical that aged animals […]
