Increasing evidence implicates neurotransmission deficits in the pathophysiology of SMA. In particular, alterations in neuroactive amino acids involved in glutamatergic neurotransmission have recently been identified in both the cerebrospinal fluid (CSF) of SMApatients and the spinal cord of SMNΔ7 mouse models. L-arginine, a precursor of nitric oxide, plays a critical role in glutamatergic receptor signalling, influencing neurotransmitter release, synaptic plasticity, and neuroprotection. However, it remains unclear whether SMN deficiency affects L-arginine metabolism in SMA. To address this, we used high-performance liquid chromatography to investigate whether SMN deficiency alters L-arginine homeostasis in the central nervous system of SMNΔ7 mice and in the CSF of SMA patients with varying disease severity, both before and after treatment with the SMN-inducing therapy Nusinersen. Notably, we observed significantly reduced L-arginine levels in the brainstem and spinal cord of symptomatic SMA mice compared to age-matched wild-type littermates. Consistent with these findings, we revealed lower L-arginine levels in severe SMA1 patients compared to milder SMA2 and SMA3 patients and healthy controls, enhancing the translational strength of our findings. Importantly, Nusinersen-mediated SMN upregulation fully restored L-arginine homeostasis in the CSF of severe SMA1 patients. In conclusion, our results demonstrate a dysregulation of L-arginine in SMA and highlight a role for SMN-enhancing therapies in restoring neurochemical alterations observed in patients with this neurodegenerative disease.</div></div>","PeriodicalId":19097,"journal":{"name":"Neurobiology of Disease","volume":"214 ","pages":"Article 107046"},"PeriodicalIF":5.6,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144768803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using electrophysiological mapping, we investigated in rats the time-course of cutaneous map remodeling in the intact hemisphere following unilateral focal damage to the forepaw area in S1 along with behavioral assessment of sensorimotor deficits. Cortical maps showed a representational dedifferentiation inducing a degradation of the somatotopic organization, starting immediately after the lesion and worsening until the end of the 14th day post-injury. These changes were underpinned by a dramatic enlargement of cutaneous receptive fields accompanied by an increase in neuronal sensitivity. Strong impairment of tactile sensitivity and sensorimotor adjustments was shown for the forepaw contralateral to the injured hemisphere, that gradually abated from the 2nd to the 7th week. Interestingly, deficits of fine sensorimotor adjustments were also observed in the “non-paretic” forepaw. They were less pronounced than in the “paretic” limb but evolved with a similar time course of recovery. A substantial restoration of somatotopic organization occurred gradually, in parallel with the functional recovery. Immediate post-lesion effects suggest an altered interhemispheric interplay and highlight the critical role of hemispheric cross influences in maintaining fine somatotopic organization of cutaneous maps in each hemisphere. S1 map normalization in intact cortex paralleling functional recovery may reflect compensatory mechanisms reorganizing interhemispheric communication and shaping cortical neurons' responses.</div></div>","PeriodicalId":19097,"journal":{"name":"Neurobiology of Disease","volume":"214 ","pages":"Article 107043"},"PeriodicalIF":5.6,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144753889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cuproptosis, which was first systematically described in 2022 as a novel form of programmed cell death, involves molecular mechanisms characterized by oxidative stress activation, inhibition of the ubiquitin-proteasome system, and aggregation of lipoacylated proteins. This cascade can compromise mitochondrial function and ultimately result in cell death.
