摘要
背景:在中枢神经系统(CNS)疾病中,缺血性和出血性中风等重要的医疗保健问题以及紧急入院的主要原因,主要影响神经血管结构。尽管死亡率高,发病率高,但迄今尚未建立起有效的治疗对象。目的:血液脑屏障(BBB)是临床研究和实验环境中检测到的主要影响的中风结构。 BBB由内皮,星形胶质细胞末端,周细胞和基底层组成。神经血管单位,周细胞和BBB形成的内皮在缺血性和出血性中风中起重要的病理生理作用。 讨论:在这个微型评论中,微循环和血脑屏障细胞在卒中病理生理学中的作用将以基于周细胞的特别重点为基础进行讨论。周细胞对于根据神经元组织的需要提供足够的微循环供应特别重要,并形成BBB的功能重要部分之一,并在神经血管耦合中发挥作用。了解神经血管单位元素在不同神经系统疾病中的作用和发病机制,为未来治疗提供新的靶点。

摘要: Background: Among the central nervous system (CNS) disorders, diseases like ischemic and hemorrhagic stroke which are important health care problems as well as leading causes for emergency admissions, primarily affect neurovascular structure. Despite their high rate of mortality and morbidity, very few efficient treatment targets have been established until now. Objective: Blood-brain barrier (BBB) is the mostly effected structure in stroke as detected in both clinical studies and experimental settings. BBB is composed of endothelia, astrocyte end-foot, pericytes and basal lamina. Neurovascular unit, pericytes and BBB forming endothelia play significant pathophysiological roles in both ischemic and hemorrhagic stroke.
Discussion: In this mini-review, the role of microcirculation and cells of blood-brain barrier in stroke pathophysiology will be discussed with a special emphasis based on pericytes. Pericytes are especially important for providing adequate microcirculatory supply according to needs of neuronal tissue and form one of the functionally important part of BBB and take role in neurovascular coupling. Understanding the role and disease producing mechanisms of neurovascular unit elements in different neurological conditions will provide novel targets for future treatments.Export Options
