However, it lacks specificity for individual tissue microstructural features, such as neurite density, orientation dispersions, and extracellular edema. Neurite orientation dispersion and density imaging (NODDI), a novel diffusion magnetic resonance imaging (MRI) technique, can provide these distinct indices. We characterized brain microstructural alterations in patients with unilateral TN using NODDI and compared the difference between left- and right-side TN (LTN and RTN, respectively). Diffusion-weighted imaging was performed on 39 patients with LTN, 37 patients with RTN, and 37 healthy controls. Neurite orientation dispersion and density imaging-related indices, including the intracellular volume fraction (Vic), orientation dispersion index (ODI), and isotropic volume fraction (Fiso), were estimated and compared using tract-based spatial statistics and voxel-based region-of-interest analysis. The LTN and RTN groups exhibited microstructural abnormalities in white and gray matter as measured by decreased fractional anisotropy and Vic and elevated Fiso, respectively. These alterations were associated with clinical features and were mainly located in the frontal lobe, corona radiata, internal capsule, and thalamus. The angular variation of neurites, characterized by ODI, exhibited no significant changes between TN and control groups. Patients with classical TN of either side exhibited reduced Vic and increased Fiso, which indicated decreased density of axons and dendrites and neuroinflammatory edema in bilateral hemispheres. Neurite orientation dispersion and density imaging is a useful technique for in vivo diffusion MRI of white and gray matter in the brain, which provides additional metrics and information closely related to the tissue microstructure that merits further study of TN pathogenesis.","PeriodicalId":19921,"journal":{"name":"PAIN®","volume":"26 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about the neurobiological phenotype of pain experiences in adolescents, particularly outside of a clinical setting. A better neurobiological understanding of pain experiences in community youth may shed light on potential vulnerabilities present before clinical diagnoses of chronic pain. This study utilized an exploratory region-of-interest approach, in a large community sample (n = 7332) of youth (ages 11-12), to examine the association between white matter microstructure, fractional anisotropy (FA) and mean diffusivity (MD), and pain experiences. Bayesian multilevel modeling was used to explore group differences (between those reporting past-month pain and those who did not), and continuous associations between pain experiences (average pain intensity, worst pain intensity, and pain-related limitations) and FA and MD. Sex differences in these effects were also explored. Analyses revealed widespread associations between pain-related limitations and lower FA and greater MD in male but not female youth. Furthermore, average pain intensity was associated with greater superior corticostriate and superior longitudinal fasciculus MD in all youth, and worst pain intensity was associated with lower inferior fronto-occipital fasciculus FA in male youth. There were no group differences in FA or MD between those with or without past-month pain. These findings suggest that white matter microstructural alterations in youth may be more related to the severity of the pain experience than to the presence or absence of pain itself, with male youth showing stronger neurobiological associations with pain-related outcomes.","PeriodicalId":19921,"journal":{"name":"PAIN®","volume":"18 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A local, long-lasting approach is desirable, yet local anesthetics are neither specific nor long-lasting. In lieu of a pore blocker approach, we show a pharmacological method targeting the scaffolding and degradation of Na V 1.8 channels, which attenuated neuropathic pain behavior in mice. Na V 1.8 channels interact with the WW domain-containing scaffold protein called Magi-1. WW domains are typically found in ubiquitin ligases, and Na V 1.8 channels are susceptible to degradation by ubiquitin ligases. Here, we show Na V 1.8 and MAGI-1 colocalized in human tissues. We demonstrate that a lipidated peptide derived from the Na V 1.8 WW binding domain, at sub-micromolar concentrations, inhibited rodent dorsal root ganglion neuronal firing. The peptide reduced Na V 1.8 channel immunoreactivity and tetrodotoxin-resistant currents in human dorsal root ganglion neurons.
