中风是一种危及生命的疾病,导致死亡,幸存者遭受长期残疾。微血管损伤是脑卒中的一个重要病理特征,也是治疗的靶点。在这篇综述中,我们提出的证据详细说明了亚急性神经联系不能在局灶性缺血性中风大鼠模型的重点是血脑屏障(BBB)的完整性和相关的致病过程中对侧脑区。此外,我们讨论了BBB能力在慢性神经机能不能在一个类似的大鼠中风模型,突出对侧脑区的病理变化,表明渐进的形态脑功能障碍后,中风发作的时间。由于神经功能不能与卒中的发作和进展密切相关,因此它是卒中的一种治疗方法。事实上,已经研究了干细胞移植用于修复微血管损伤的用途,证明了静脉内移植到中风后48小时的大鼠中的骨髓干细胞存活并整合到微血管中。移植的中风脑的超微结构分析显示,微血管显示内皮细胞及其线粒体的接近正常的形态。基于细胞的治疗代表了脑卒中BBB和微血管修复的新机制。
Stroke is a life-threatening disease that leads to mortality, with survivors subjected to long-term disability. Microvascular damage is implicated as a key pathological feature, as well as a therapeutic target for stroke. In this review, we present evidence detailing subacute diaschisis in a focal ischemic stroke rat model with a focus on blood–brain barrier (BBB) integrity and related pathogenic processes in contralateral brain areas. Additionally, we discuss BBB competence in chronic diaschisis in a similar rat stroke model, highlighting the pathological changes in contralateral brain areas that indicate progressive morphological brain disturbances overtime after stroke onset. With diaschisis closely approximating stroke onset and progression, it stands as a treatment of interest for stroke. Indeed, the use of stem cell transplantation for the repair of microvascular damage has been investigated, demonstrating that bone marrow stem cells intravenously transplanted into rats 48 h post-stroke survive and integrate into the microvasculature. Ultrastructural analysis of transplanted stroke brains reveals that microvessels display a near-normal morphology of endothelial cells and their mitochondria. Cell-based therapeutics represent a new mechanism in BBB and microvascular repair for stroke.
