Zinc (Zn) deficiency is a clinical consequence of brain injury that can result in neuropathological outcomes that are exacerbated with age. Here, we present laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) imaging data showing modulation of brain Zn levels by the disaccharide trehalose in aged mice following a controlled cortical impact model of traumatic brain injury. In this proof-of-concept study, trehalose induced an increase in brain zinc levels, providing important preliminary data for larger studies using this simple carbohydrate as a modulator of this essential micronutrient in traumatic brain injury. Our results may have further implications for the treatment of a variety of neurodegenerative diseases and other disorders of the nervous system.
锌(Zn)缺乏是脑损伤的临床后果,可能导致神经病理学结果随着年龄的增长而恶化。在这里,我们展示了激光烧蚀-电感耦合等离子体质谱(LA-ICP-MS)成像数据,这些数据显示在创伤性脑损伤的对照皮质撞击模型后,二糖海藻糖调节老年小鼠大脑 Zn 水平。在这项概念验证研究中,海藻糖诱导大脑锌水平升高,为使用这种简单碳水化合物作为创伤性脑损伤中这种必需微量元素调节剂的更大规模研究提供了重要的初步数据。我们的结果可能对治疗各种神经退行性疾病和其他神经系统疾病有进一步的影响。
