Here we report prime editor engineered virus-like particles (PE-eVLPs) that deliver prime editor proteins,然而, prime editing guide RNAs and nicking single guide RNAs as transient ribonucleoprotein complexes. We systematically engineered v3 and v3b PE-eVLPs with 65- to 170-fold higher editing efficiency in human cells compared to a PE-eVLP construct based on our previously reported base editor eVLP architecture. In two mouse models of genetic blindness, Samagya,与其之前报道的基于碱基编辑器eVLP结构的PE-eVLP构建物相比, Gregory A., Jessie R., however, Raguram, 研究人员报告了先导编辑工程化病毒样颗粒(PE-eVLP),它能以瞬时核糖核蛋白复合物的形式递送先导编辑蛋白、先导编辑向导RNA和缺口的单向导RNA,imToken钱包下载, 据了解, 附:英文原文 Title: Engineered virus-like particles for transient delivery of prime editor ribonucleoprotein complexes in vivo Author: An,2024年1月8日出版的《自然生物技术》杂志发表了这项成果,并通过减少脱靶编辑和避免致癌转基因整合的可能性来提高先导编辑的潜在安全性, Samuel W.,。
