大脑的生理屏障损害了治疗许多神经系统疾病的药物输送。基于rna的适体是一种尚未研究其穿透大脑能力的递送方法。这些分子可以传递给外周组织和循环免疫细胞,在那里它们充当配体模拟物或可以修饰以携带有效载荷。我们开发了一个适体库和一个体内进化方案,以确定是否可以识别特定的适体,这些适体在注射到外周血管系统后会回到大脑。与重组噬菌体文库的生物筛选不同,我们发现这里使用的适体文库需要超过15轮的体内选择才能收敛到特定序列。通过这种方法鉴定出的适体结合到脑毛细血管内皮并渗透到薄壁组织中。所描述的方法可能会发现针对大脑的各种有效载荷的通用效用。
The physiological barriers of the brain impair drug delivery for treatment of many neurological disorders. One delivery approach that has not been investigated for their ability to penetrate the brain is RNA-based aptamers. These molecules can impart delivery to peripheral tissues and circulating immune cells, where they act as ligand mimics or can be modified to carry payloads. We developed a library of aptamers and an in vivo evolution protocol to determine whether specific aptamers could be identified that would home to the brain after injection into the peripheral vasculature. Unlike biopanning with recombinant bacteriophage libraries, we found that the aptamer library employed here required more than 15 rounds of in vivo selection for convergence to specific sequences. The aptamer species identified through this approach bound to brain capillary endothelia and penetrated into the parenchyma. The methods described may find general utility for targeting various payloads to the brain.
