Despite heterogeneous aetiologies, chronic pain states converge on shared pathophysiological mechanisms: peripheral and central sensitisation. These dysfunctions reflect long-term functional and structural plasticity within the peripheral and central nociceptive pathways, resulting in amplified signal transmission and pain chronification. Historically, research and drug development prioritised peripheral targets to suppress nociceptive inputs, often neglecting central sensitisation, a core mechanism of treatment-resistant pain. Sensitisation of dorsal horn (DH) circuits underlies network hyperexcitability associated with disrupted excitation-inhibition balance, synaptic potentiation, and circuit reorganisation. This review summarises recent advances in delineating synaptic, cellular, and DH network-level adaptations underlying chronic pain. We discuss emerging mechanism-based strategies to restore circuit balance by targeting cell-type-specific maladaptive plasticity rather than globally suppressing neural activity.

ARS selectively increased the activity of dmPFC projection neurons (PNs) at 2 h, but not 24 h post-stress, with minimal ventromedial prefrontal cortex engagement.

We observed that different anesthesia modalities induced distinct changes in cortical arteriovenous microvascular hemodynamics, suggesting a potential association between metabolic alterations and cerebrovascular regulation.

For decades, a central paradox has challenged the field: how can PHOX2B's seemingly restricted expression in the brainstem account for the broad, multi-system clinical phenotypes observed in patients? Here, we elucidate how this paradox has been resolved by recent methodological advances. We synthesize evidence from multiple complementary methodologies, including single-cell transcriptomics, spatial transcriptomics, and viral circuit tracing, which have revealed a vastly expanded PHOX2B anatomical landscape. These advances uncover previously unrecognized expression in caudal midbrain and higher brainstem regions, supportive glial populations, and peripheral components, extending far beyond classical autonomic nuclei. Furthermore, while mapping evidence predominantly derives from murine models, insights from human disease models, such as pluripotent stem cell-derived brainstem organoids, suggest that PHOX2B orchestrates integrated neuro-glial networks rather than isolated functions. Consequently, we propose reconceptualizing CCHS and related conditions as a class of multi-system network disorders termed PHOX2B circuitopathies. This circuitopathy framework critically differentiates primary circuit disruptions from secondary systemic cascades (such as hypoxia-induced cognitive deficits), providing a cohesive mechanistic basis for the constellation of cardiovascular, metabolic, and neurobehavioral symptoms. Crucially, it advances the field beyond the reactive, symptomatic management predominantly outlined in current clinical guidelines. By shifting the focus toward proactive, precision drug discovery and circuit-targeted strategies, this paradigm establishes a roadmap for developing network-based biomarkers and exploring novel disease-modifying interventions beyond conventional ventilatory support.</p>","PeriodicalId":19314,"journal":{"name":"Neuroscience bulletin","volume":" ","pages":"2381-2392"},"PeriodicalIF":6.8,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13642860/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148252529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
