1595-基于合成蛋白组装的自下而上RNA转运载体

from 聊聊Sci

这些研究介绍了一种名为合成转移载体(STV)的创新型核糖核酸(RNA)递送系统,该系统利用生成式人工智能(AI)从头设计非天然蛋白质组装体。科研人员通过筛选超过100种具有独特对称结构的载体,成功研发出性能卓越的STV-C8,其在RNA转运效率上比传统的脂质纳米颗粒(LNP)和病毒样颗粒高出数个数量级。这种新型载体不仅能通过计算设计的肽结合剂实现细胞类型特异性的精准靶向,还具有极佳的安全性和更广的货物装载容量。实验证明,STV-C8能高效递送基因编辑工具和抗病毒药物,并已在治疗杜氏肌营养不良症(DMD)的猪模型和人类细胞实验中展现出显著的临床应用潜力。这项工作标志着人类能够超越自然进化的限制,利用人工智能辅助的蛋白质工程来定制化开发生物医学转运系统。References:Schuhmacher M K, Gruber C, Lang C M R, et al.
