Resilience to Pain-Related Depression in σ Receptor Knockout Mice Is Associated with the Reversal of Pain-Induced Brain Changes in Affect-Related Genes.

Mice lacking the σ receptor chaperone (σR) are resilient to depressive-like behaviors secondary to neuropathic pain. Examining the resilience’s brain mechanisms could help develop conceptually novel therapeutic strategies. We explored […]

Widespread pain with nociplastic features is an independent predictor of low physical activity in people with multiple sclerosis.

Exploring the relationship between underlying pain mechanism and physical activity could inform interventions to optimize physical activity in persons with multiple sclerosis (PwMS). This cross-sectional nationwide survey examined whether pain […]

Sensitivity and specificity of a neuropathic screening tool (Self-report Leeds Assessment of Neuropathic Symptoms and Signs, S-LANSS) in adolescents with moderate-severe chronic pain.

Neuropathic screening tools improve recognition of neuropathic pain in adults. Although utilized in pediatric populations, the sensitivity, specificity and methodology of screening tool delivery have not been compared in children. […]

Sensory neuron-specific long noncoding RNA in small non-peptidergic dorsal root ganglion neurons selectively impairs nerve injury-induced mechanical hypersensitivity.

Nerve injury-induced mechanical hypersensitivity is one of major clinical symptoms in neuropathic pain patients. Understanding molecular mechanisms underlying this symptom is crucial for developing effective therapies. The present study was […]

Cognitive rehabilitation and aerobic exercise for cognitive impairment in people with progressive multiple sclerosis (CogEx): a randomised, blinded, sham-controlled trial.

Cognitive dysfunction in people with relapsing-remitting multiple sclerosis can improve with cognitive rehabilitation or exercise. Similar effects have not been clearly shown in people with progressive multiple sclerosis. We aimed […]

Wnt signaling is involved in crotalphine-induced analgesia in a rat model of neuropathic pain.

The aberrant activation of Wnt/β-catenin and atypical Wnt/Ryk signaling pathways in the spinal cord is critical for the development and maintenance of neuropathic pain. Crotalphine is a structural analog to […]

Brain-computer interface relieves chronic chemotherapy-induced peripheral neuropathy: A randomized, double-blind, placebo-controlled trial.

Chemotherapy-induced peripheral neuropathy (CIPN) includes negative sensations that remain a major chronic problem for cancer survivors. Previous research demonstrated that neurofeedback (a closed-loop brain-computer interface [BCI]) was effective at treating […]

Evaluation of trans- and cis-4-[18F]fluorogabapentin for brain PET imaging.

Gabapentin, a selective ligand for the α2δ subunit of voltage-dependent calcium channels, is an anticonvulsant medication used in the treatment of neuropathic pain, focal epilepsy and other neurological conditions. We […]

Disruption of Ordered Membrane Domains as a Mechanism Underlying Neuropathic Pain.

Cell membranes consist of heterogeneous lipid domains that influence key cellular processes, including signal transduction, endocytosis, and electrical excitability. The goal of this study was to assess the size of […]
