955-基于ProAPOBECs的高效体内RNA碱基编辑平台

from 聊聊Sci

这项研究介绍了一种名为ProAPOBECs的新型RNA碱基编辑平台,旨在实现更精确且高效的遗传疾病治疗。研究人员通过人工智能辅助设计与结构优化,将工程化的胞苷脱氨酶与PUF蛋白融合,克服了传统CRISPR系统在C-to-U编辑中的效率瓶颈与脱靶风险。实验证明,该系统能有效降低小鼠体内的胆固醇水平,并成功修复了自闭症模型小鼠脑部的基因突变,显著缓解了相关病理表型。这一进展不仅拓宽了碱基编辑的序列覆盖范围,更展示了in vivo(体内)RNA编辑在神经系统及代谢疾病中的巨大治疗潜力。References:Han W, Yuan B, Fan X, et al.
