中文摘要

在此期间，合作团队开发了模拟外切体组成的脂泡的生产方法。这些小泡被用来包裹小的荧光分子，而在这些小泡中加入功能化的磷脂使点击化学的使用成为可能。这种方法将允许连接能够促进跨细胞穿越血脑屏障的配体。该团队目前正在验证修剪和修改抗体Fc区域的多糖的方法，以促进点击化学，目的是点击这些抗体到脂质囊泡。
英文摘要
During this period, the collaborative team developed methods to produce lipidic vesicles mimicking the composition of exosomes. These vesicles were used to encapsulate small fluorescent molecules, and incorporation of functionalized phospholipids within these vesicles enabled the use of click chemistry. This approach will allow the attachment of ligands able to promote transcytosis across the blood-brain barrier. The team is currently validating methods to trim and modify the glycan of the Fc domain of antibodies to facilitate click chemistry, with the aim of clicking these antibodies to lipidic vesicles.
