In the pathogenesis of major depressive disorder, chronic stress-related neuroinflammation hinders favorable prognosis and antidepressant response. Mitochondrial DNA may be an inflammatory trigger, after its release from stress-induced dysfunctional central nervous system mitochondria into peripheral circulation. This evidence supports the potential use of peripheral mitochondrial DNA as a neuroinflammatory biomarker for the diagnosis and treatment of major depressive disorder. Herein, we critically review the neuroinflammation theory in major depressive disorder, providing compelling evidence that mitochondrial DNA release acts as a critical biological substrate, and that it constitutes the neuroinflammatory disease pathway. After its release, mitochondrial DNA can be carried in the exosomes and transported to extracellular spaces in the central nervous system and peripheral circulation. Detectable exosomes render encaged mitochondrial DNA relatively stable. This mitochondrial DNA in peripheral circulation can thus be directly detected in clinical practice. These characteristics illustrate the potential for mitochondrial DNA to serve as an innovative clinical biomarker and molecular treatment target for major depressive disorder. This review also highlights the future potential value of clinical applications combining mitochondrial DNA with a panel of other biomarkers, to improve diagnostic precision in major depressive disorder.

华北克拉通和巴西圣弗朗西斯科-刚果克拉通新元古代早期的岩墙和岩床及玄武岩(ca.940~890Ma)岩浆活动时间对比和古地磁研究结果表明,上述克拉通在新元古代可能相邻。这些阶段性岩浆作用的演化趋势和源区特征及其所反映的地质过程与构造背景对进一步开展大陆重建有重要意义。本文系统总结和对比分析了两个克拉通新元古代镁铁质岩石的岩相学、地球化学和同位素年代学数据。研究发现,这些岩石大致可分为两类多期:(1)年龄较老(ca.940~920Ma)且演化的高Ti岩石(MgO2%),负Eu异常明显(Eu/Eu^(*)=0.7~1.0);(2)年龄较年轻(ca.915~890Ma)且较为原始的低Ti岩石(MgO>6.5%,TiO_(2)<2%),具有正Eu异常(Eu/Eu^(*)=1~1.2)或者没有Eu异常(Eu/Eu=1)。早期高Ti岩浆源区类似于EMⅠ型地幔端元(ε_(Nd)(t)=-8~+3),Sr-Nd同位素特征表明其可能是软流圈上涌熔融产生的岩浆与岩石圈地幔相互作用的结果;而晚期低Ti岩石Nd同位素与球粒陨石值类似(ε_(Nd)(t)=-2~+3),可能来源于软流圈地幔。这两类岩石在华北克拉通和巴西圣弗朗西斯科-刚果克拉通几乎同时出现,且可类比。岩浆演化趋势、微量元素和Sr-Nd同位素等特征及单斜辉石-熔体平衡深度计算表明,早期高Ti岩浆产生于大陆岩石圈破裂初期,经历了较高程度的结晶分异作用;而晚期低Ti岩浆的持续作用(~30Myr)可能与岩石圈破裂过程中不断增强的软流圈岩浆活动相关。该裂谷演化进程在Sr同位素特征变化上也有体现,即与早期高Ti岩石相比,晚期低Ti岩石的Sr同位素更为富集但Nd同位素保持不变,表明该类岩石的产生可能在大陆裂谷发育过程中受到海水蚀变的影响。以上证据表明,华北克拉通和巴西圣弗朗西斯科-刚果克拉通在新元古代早期具有可类比的岩石圈应力演化状态,且经历了相似的地幔地球化学动力学过程,支持两个克拉通在该时期相邻。
