Central nervous system (CNS) disorders present major therapeutic challenges due to the presence of the blood - brain barrier (BBB) and disease heterogeneity. The BBB impedes most therapeutic agents, which restricts conventional treatments. Focused ultrasound (FUS) -assisted delivery offers a novel solution by temporarily disrupting the BBB and thereby enhancing drug delivery to the CNS.
This review outlines the fundamental principles of FUS-assisted drug delivery technology, with an emphasis on its role in enhancing the spatial precision of therapeutic interventions and its molecular effects on the cellular composition of the BBB. Recent promising clinical studies are surveyed, and a comparative analysis of current US-assisted delivery system is provided. Additionally, the latest advancements and challenges of this technology are discussed.
FUS-mediated drug delivery shows promise, but the clinical translation of research findings is challenging. Key issues include safety, dosage optimization, and balancing efficacy with the risk of tissue damage. Continued research is crucial to address these challenges and bridge the gap between preclinical and clinical applications, and could transform treatments of CNS disorders.
由于血脑屏障(BBB)的存在和疾病异质性,中枢神经系统(CNS)疾病带来了重大的治疗挑战。血脑屏障阻碍了大多数治疗药物,限制了传统治疗方法。聚焦超声(FUS)辅助给药通过暂时破坏血脑屏障,从而增强药物向中枢神经系统的递送,提供了一种新的解决方案。
本综述概述了FUS辅助给药技术的基本原理,重点强调其在提高治疗干预的空间精度方面的作用及其对血脑屏障细胞组成的分子效应。调查了近期有前景的临床研究,并对当前的超声辅助给药系统进行了比较分析。此外,还讨论了该技术的最新进展和挑战。
FUS介导的药物递送显示出前景,但研究结果的临床转化具有挑战性。关键问题包括安全性、剂量优化以及在疗效与组织损伤风险之间取得平衡。持续的研究对于应对这些挑战以及弥合临床前和临床应用之间的差距至关重要,并且可能会改变中枢神经系统疾病的治疗方法。
