作为一名神经学家和微血管学专业的学生,我很高兴能介绍这篇论文。本文从血脑屏障(BBB)的角度对脑病理生理学和治疗进行了综述。几乎所有影响大脑的疾病过程--创伤性、肿瘤性、感染性、炎症性、毒性、代谢性、退行性、血管和癫痫--都会影响血脑屏障。这种动态平衡系统的破坏通常会导致脑液成分和容量的破坏,从而导致神经症状和病理。此外,在屏障的完整性没有被破坏的障碍中,其正常的限制性性质可能会限制治疗方法。例如,帕金森病患者的脑组织屏障似乎功能正常,但其弥补纹状体多巴胺耗竭的能力部分取决于脑微血管系统中的转运蛋白和酶的活性。抗生素、抗惊厥药、抗肿瘤药和神经麻风药的选择同样需要注意这些药物与血脑屏障的相互作用。因此,这一障碍几乎与所有神经系统疾病和治疗方法都有关联。未来使用调节肽、免疫介体和基因组件进行大脑治疗将需要有选择的方法将这些药物输送到特定的大脑区域。这篇文章的第二卷成功地对血脑屏障在各种临床情况下的功能和衰竭进行了彻底的回顾。“
As a neurologist and student of the microvasculature, I find great pleasure in introducing this treatise. Presented here is a view of brain pathophysiology and therapy from the perspective of the blood-brain barrier (BBB). Virtually every disease process that affects the brain-traumatic, neoplastic, infectious, inflammatory, toxic, metabolic, degenera tive, vascular, and epileptic-affects the BBB. Damage to this homeostatic system often leads to disruption of the composition and volume of brain fluid compartments, thereby contributing to neurologic symptoms and pathology. Furthermore, in disorders in which the integrity of the barrier is not breached, its normal restrictive nature may limit therapeu tic approaches. For example, the barrier appears to function normally in Parkinson dis ease, but its ability to compensate for striatal dopamine depletion is in part determined by the activity of transporters and enzymes operative in the brain microvasculature. of antibiotics, anticonvulsants, antineoplastic agents, and neurolep Similarly, the choice tics requires attention to these drugs' interaction with the BBB. Thus, the barrier inter faces with virtually all nervous system diseases and therapies. Future brain treatments with regulatory peptides, immune mediators, and gene components will require selective methods to deliver these agents to specific brain regions. The second volume of this text successfully provides a thorough review of BBB function and failure in a variety of clinical situations."
