Abstract

The blood-brain barrier (BBB) is one of the most selective endothelial barriers that protect the brain and maintains homeostasis in neural microenvironments. This barrier restricts the passage of molecules into the brain, except for gaseous or extremely small hydrophobic molecules. Thus, the BBB hinders the delivery of drugs with large molecular weights for the treatment of brain cancers. Various methods have been used to deliver drugs to the brain by circumventing the BBB; however, they have limitations such as drug diversity and low delivery efficiency. To overcome this challenge, microbubbles (MBs)-based drug delivery systems have garnered a lot of interest in recent years. MBs are widely used as contrast agents and are recently being researched as a vehicle for delivering drugs, proteins, and gene complexes. The MBs are 1-10 μm in size and consist of a gas core and an organic shell, which cause physical changes, such as bubble expansion, contraction, vibration, and collapse, in response to ultrasound. The physical changes in the MBs and the resulting energy lead to biological changes in the BBB and cause the drug to penetrate it, thus enhancing the therapeutic effect. Particularly, this review describes a state-of-the-art strategy for fabricating MB-based delivery platforms and their use with ultrasound in brain cancer therapy.

摘要

血脑屏障(BBB)是最具选择性的内皮屏障之一,可保护大脑并维持神经微环境中的稳态。除气态或极小的疏水分子外,该屏障限制分子进入大脑。因此,血脑屏障阻碍了用于治疗脑癌的大分子药物的递送。人们已采用各种方法绕过血脑屏障将药物递送至大脑;然而,它们存在诸如药物多样性和递送效率低等局限性。为克服这一挑战,近年来基于微泡(MBs)的药物递送系统引起了广泛关注。微泡被广泛用作造影剂,最近正被研究作为递送药物、蛋白质和基因复合物的载体。微泡大小为1 - 10μm,由气体核心和有机外壳组成,响应超声会引起诸如气泡膨胀、收缩、振动和塌陷等物理变化。微泡的物理变化及其产生的能量会导致血脑屏障发生生物学变化,并使药物穿透血脑屏障,从而增强治疗效果。特别是,本综述描述了一种用于制造基于微泡的递送平台及其在脑癌治疗中与超声联合使用的先进策略。
