摘要:

脉络丛上皮细胞被认为是存在于心室壁谱系的室管膜终末分化细胞,血-脑脊液屏障既由脉络丛上皮细胞单层形成。与此相反的血-脑屏障,是由内皮细胞在脑毛细血管水平形成的,脉络丛上皮细胞被定位于有孔毛细管并存在于交界相邻脉络丛上皮细胞分子顶部,限制病原体从血液入口进入大脑。血-脑脊液屏障中的脉络丛上皮以内皮细胞都与血-脑屏障密切相关。文章中表示脉络丛上皮已建立起几个功能:它保护因机械性脑外伤造成的血压变化,并允许不同的分子通过整个中枢神经系统进行运输,进而利于除去毒素和废物。因此,脉络丛-脉络丛上皮系统在生理过程中起到了积极作用,如发育、修复和维护大脑的动态平衡。脉络丛在脑稳态中发挥关键作用。由于其结构,功能和位置的特性,脉络丛-脉络丛上皮系统对中枢神经系统功能生理和病理都有显著影响。脉络丛上皮细胞紧密连接,从而防止不受控制的血液泄漏进入脉络丛上皮,并且脉络丛可以控制炎性细胞流入大脑。脉络丛上皮细胞含有大量的运转因子,并且能够分泌积极分子,从而向大脑传播炎症反应。另外,脉络丛上皮细胞在清除毒性分子,例如Aβ也发挥显著作用。在老化和阿尔茨海默病中,脉络丛上皮细胞功能通过结构完整性和分泌活性损失反映衰老的影响,从而对疾病的进展产生负面作用。因此通过靶向脉络丛-脉络丛上皮系统是很有前景的治疗神经退行性疾病策略。

Abstract:

The choroid plexus is a complex structure which hangs inside the ventricles of the brain and consists
mainly of choroid plexus epithelial (CPE) cells surrounding fenestrated capillaries. These CPE cells not
only form an anatomical barrier, called the blood-cerebrospinal fluid barrier (BCSFB), but also present an
active interface between blood and cerebrospinal fluid (CSF). CPE cells perform indispensable functions
for the development, maintenance and functioning of the brain. Indeed, the primary role of the choroid
plexus in the brain is to maintain homeostasis by secreting CSF which contains different molecules, such as
nutrients, neurotrophins, and growth factors, as well as by clearing toxic and undesirable molecules from
CSF. The choroid plexus also acts as a selective entry gate for leukocytes into the brain. Recent findings have
revealed distinct changes in CPE cells that are associated with aging and Alzheimer’s disease. In this review,
we review some recent findings that highlight the importance of the CPE-CSF system in Alzheimer’s disease
and we summarize the recent advances in the regeneration of brain tissue through use of CPE cells as a
new therapeutic strategy.
