异常的氧化还原信号是许多慢性代谢疾病(包括 2 型糖尿病 (T2D))病理生理学的基础。旨在重新平衡全身氧化还原稳态的方法取得的成功有限。无创、持续的方法将能够长期控制氧化还原信号传导以治疗 T2D。我们报告说,静磁场和电场(sBE)无创地调节系统性 GSH-to-GSSG 氧化还原对,以促进更健康的系统性氧化还原环境。引人注目的是,当应用于 T2D 小鼠模型时,sBE 在短短三天内迅速改善胰岛素抵抗和葡萄糖耐受不良,并且没有观察到不良反应。在肝线粒体中用 SOD2 清除氧代谢的顺磁性副产物可以完全消除这些胰岛素增敏作用,表明线粒体超氧化物介导这些治疗变化的诱导。我们的研究结果引入了一种显着的氧化还原调节现象,该现象利用内源性电磁接收机制来无创治疗 T2D 以及其他潜在的氧化还原相关疾病。
Aberrant redox signaling underlies the pathophysiology of many chronic metabolic diseases, including type 2 diabetes (T2D). Methodologies aimed at rebalancing systemic redox homeostasis have had limited success. A noninvasive, sustained approach would enable the long-term control of redox signaling for the treatment of T2D. We report that static magnetic and electric fields (sBE) noninvasively modulate the systemic GSH-to-GSSG redox couple to promote a healthier systemic redox environment that is reducing. Strikingly, when applied to mouse models of T2D, sBE rapidly ameliorates insulin resistance and glucose intolerance in as few as three days with no observed adverse effects. Scavenging paramagnetic byproducts of oxygen metabolism with SOD2 in hepatic mitochondria fully abolishes these insulin sensitizing effects, demonstrating that mitochondrial superoxide mediates induction of these therapeutic changes. Our findings introduce a remarkable redox-modulating phenomenon that exploits endogenous electromagneto-receptive mechanisms for the noninvasive treatment of T2D, and potentially other redox-related diseases.
