Participants (n = 233) were assessed at <1, 3, 6, and 12 months after whiplash injury. Outcomes were cold pain detection threshold (CPT at neck), pressure pain detection thresholds (PPT, neck C5, and tibialis anterior), and the Neck Disability Index. We used group-based trajectory models to identify postinjury recovery trajectories and multinominal logistic regression to explore associations between baseline characteristics and trajectory membership. We identified the following trajectory groups: CPT (low [50.0%], moderate [29.7%], and high [20.4%] sensitivity); PPT C5 (low [10.8%] and high [89.2%] sensitivity); and PPT tibialis anterior (low [23.9%], moderate [39.0%], and high [37.1%] sensitivity); all were stable over the 12 months. There was good correspondence between disability and cold sensitivity trajectory groups but not for mechanical sensitivity; cold and mechanical sensitivity trajectories were not well associated. Higher baseline pain predicted membership of the high cold sensitivity trajectory (RR 1.27, 95% CI 1.01-1.59) and hyperarousal symptoms predicted membership of the moderate cold sensitivity trajectory (RR 1.17, 95% CI 1.01-1.36). We found no associations between baseline characteristics and mechanical sensitivity. There is an interplay between cold allodynia, pain, and hyperarousal symptoms in development of ongoing disability after whiplash injury.

Likewise, the pannexin 1 (Panx1) channel has been described as necessary for initiating and maintaining neuropathic pain, driving nociceptive signals dependent on spinal NMDAR through several possible mechanisms. Through behavioral, pharmacological, and molecular approaches, our study in male rats has revealed several key findings: (1) neurons located in spinal cord laminae I and II express functional Panx1 channels in both neuropathic and sham rats. These channels can open (indicated by YOPRO-1 uptake) through the stimulation of NMDARs with intrathecal NMDA; (2) intrathecal NMDA leads to increased expression of pSrc and pPanx1 in dorsal horn neurons. This elevation exacerbates existing mechanical hyperalgesia in nerve-injured rats; (3) inhibition of Src with intrathecal PP2 or blockade of Panx1 with intrathecal 10 Panx effectively mitigates NMDA-induced effects and reduces the spontaneous mechanical hyperalgesia of nerve-injured rats. Notably, while 10 Panx successfully alleviates hyperalgesia, it does not alter pSrc expression; and (4) NMDA-stimulated YOPRO-1 uptake in neurons of laminae I-II of spinal cord slices were prevented by the NMDAR antagonist D-AP5, the Src inhibitor PP2 (but not PP3), as well as with the 10 Panx and carbenoxolone. Therefore, NMDAR activation in dorsal horn neurons triggers an NMDAR-Src-Panx1 signaling pathway, where Panx1 acts as an enhancing effector in neuropathic pain. This implies that disrupting the NMDAR-Panx1 communication (eg, through Src inhibitors and/or Panx1 blockers) may offer a valuable strategy for managing some forms of chronic pain.</p>","PeriodicalId":19921,"journal":{"name":"PAIN®","volume":" ","pages":"1369-1381"},"PeriodicalIF":5.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12067615/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142771234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
