While traumatic spinal cord injury (TSCI), caused by acute external forces, is well-researched, non-traumatic spinal cord injury (NTSCI), arising from chronic conditions like tumors and infections, is often underreported and misclassified. NTSCI is increasingly recognized as a major cause of SCI globally, particularly affecting the elderly and infants. Despite its prevalence, research on NTSCI remains limited, necessitating new models to understand its pathophysiology. This study introduces a novel, repeatable model for NTSCI in both neonatal (9 days post-partum) and adult rats (9 weeks post-partum), simulating chronic compression injuries. The model uses 3D-printed (PLA) spacers to induce mild–moderate compression in the lower thoracic vertebrae. Six weeks of spinal cord compression resulted in locomotor deficits and cellular changes consistent with hypoxic–ischemic injury due to disrupted blood flow, without significant long-term inflammation or astrogliosis. This versatile model can be easily adapted for different age groups, for graded injury severities, and for different injury durations. It offers a promising avenue for understanding and treating chronic compression NTSCI, addressing a critical gap in current research. This model can be used in future research to test and understand the effectiveness and pathophysiology of decompression and cellular interventions in response to chronic compression NTSCI.</p>\u0000 </div>","PeriodicalId":16490,"journal":{"name":"Journal of Neuroscience Research","volume":"103 11","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145431726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Axons subjected to this mechanical stretch injury exhibit diverse pathological changes, including disruption of axonal transport, neurofilament compaction and degradation, myelin sheath disruption, and loss of sodium channels required for action potential generation and propagation. These distinct forms of axonal pathology may evolve differentially over time and preferentially localize to specific white matter tracts. In this study, we employed the clinically relevant ferret model of concussion using the closed head impact model of engineered rotational acceleration (CHIMERA). 55 male ferrets were randomly allocated to sham or injury groups and then to either 24 h, 72 h, or 14d survival time points. We confirmed that axonal transport disruption and neurofilament pathology represent independent processes, with minimal colocalization but a shared peak of around 72 h following injury. Furthermore, we observed a persistent loss of ankyrin-G, a critical anchoring protein for sodium channels at the node of Ranvier, up to 14d postinjury, suggesting that the resultant impairment in axonal transmission may underlie many concussion symptoms. Indeed, injured ferrets displayed significant deficits in balance, working memory, spatial memory, and recognition memory. These findings demonstrate that the CHIMERA model in ferrets recapitulates key axonal pathologies and their associated clinical manifestations following concussion. This model offers a valuable platform for investigating the temporal evolution of axonal injury and developing targeted therapeutic interventions to mitigate concussion-related deficits.</p>\u0000 </div>","PeriodicalId":16490,"journal":{"name":"Journal of Neuroscience Research","volume":"103 11","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145385101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While post-mortem studies suggest abnormalities in SIDS infants' brainstems, there are no studies of these infants' brainstem function before death. One way to assess the function of the brainstem is with auditory brainstem response (ABR), a routine hearing-screening method that noninvasively measures the brainstem's response to sound.

As hypothesized, infants who died from SIDS were more likely than non-SIDS infants to have abnormal ABRs as newborns. Children who died of SIDS appeared to have shorter latencies to the trough that follows peak V in the left ear than children without SIDS. However, our expert-rated data failed to replicate this finding, suggesting it is unlikely to reflect a true effect.

This study was conducted to determine whether chronic moderate treadmill exercise prevents dopaminergic neuron loss and Lewy body-like inclusion burden in a preclinical model of PD. This study also sought to identify plasma exosome bound “exerkines” with potential to induce neuroprotective brain adaptations. Benefits of exercise are thought to be achieved in part through nucleic acids, lipids, and peptides termed exerkines abundant during exercise. These exerkines can induce cell-specific exercise adaptations culminating in neuroprotection. Membrane-free exerkines are subject to degradation in blood and may not effectively cross the blood-brain barrier to induce brain adaptations to exercise, limiting their inter-organ signaling potential. This led us to hypothesize that exerkines, bioactive RNAs in particular, may be selectively packaged into exosomes and released into plasma during exercise. Exosomes are small extracellular vesicles, selectively packaged and released by cells, with likely important differences in composition at rest, during injury and disease, and in response to exercise. Exosomes have been demonstrated to play a major role in inter-organ communication. Chronic exercise was found to provide neuroprotection to dopaminergic neurons in the substantia nigra pars compacta, without affecting Lewy body-like inclusion burden in the nigra or the striatum.

UVB hyperacceleration can result in injury independent of impact; however, a secondary impact injury can also occur. To date, translation of findings from rodent TBI models to improved patient outcomes has been unsuccessful, perhaps due to neuroanatomical differences between humans and rodents, including white-to-gray matter ratio and cortical gyrification. To address this modeling difference, a UVB model was developed in ferrets, the brains of which more closely resemble humans. Male ferrets underwent UVB-alone (Blast), controlled cortical impact (CCI)-alone, combined UVB + CCI (BCCI), or craniotomy (Sham) procedures. Neurobehavioral assays were optimized and used to assess mood, memory, and motor control. Blast and BCCI ferrets underwent neuroimaging at baseline and 7 days post-injury. All ferrets were euthanized by terminal perfusion with paraformaldehyde on day 7 for histologic analysis. Results indicate that UVB alters cortical metabolites and induces blood–brain barrier (BBB) disruption. CCI leads to BBB disruption and cortical diffuse axonal injury, but this is not exacerbated by combination with UVB. BCCI does result in several alterations in key cortical metabolites indicative of increased neuronal injury, oxidative stress, and glial activation as well as impaired neurotransmission and energy generation. Additionally, BCCI significantly increases hyperactivity and impairs spatial memory. Anxiety-like behavior, mood, and motor function approached statistical significance. Taken together, we provide a military-relevant model of UVB in a gyrencephalic animal, the ferret, that may be applied in future investigations into TBI pathophysiology and potential treatment.</p>","PeriodicalId":16490,"journal":{"name":"Journal of Neuroscience Research","volume":"103 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jnr.70081","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
