Studies on peptides mediated gelatin-siloxane nanoparticles for crossing the blood-brain barrier

Abstract

脑毛细血管内皮细胞及其之间丰富的紧密连接在血脑屏障的构成起了关键作用,并在中枢神经系统内环境稳定的维持中极为重要,但是,血脑屏障的存在也阻止了许多诊断、治疗制剂转运入中枢神经系统组织内,成为入脑转运难以克服的障碍。据研究,有98%的小分子及全部的大分子诊断、治疗制剂被限制转运到脑实质组织内。因此,近年来研究者使用了各种各样的方法尝试去克服这一难题,特别是多功能药物递送系统备受瞩目。纳米粒子在脑部药物递送系统的应用中具有广阔的前景,已在肿瘤诊断、药物转运及靶向治疗方面显示出巨大优势。无机明胶-硅氧烷纳米粒子已被验证具有良好的包载及释放DNA的性能。 本研究,首先通过两步溶胶-凝胶法,合成了明胶...The blood–brain barrier (BBB) is primarily formed by specialized brain endothelial cells that are interconnected by well-developed tight junctions and provides a significantly important for maintaining the stability of the CNS inner environment, but the barrier is also represents an insurmountable obstacle for the delivery of many important diagnostic and therapeutic agents entering into the centr...学位:医学硕士院系专业:医学院临床医学系_外科学学号:2452008115346
