项目摘要

Project Summary The ability to correct disease gene mutations in vivo has broad potential utility for both therapy and basic research. CRISPR/Cas9 is a powerful RNA-guided tool for genome editing. Our recent discovery that CRISPR/Cas9 delivery can cure genetic disease in adult mouse liver provided proof-of-concept of gene correction therapy in vivo. The main goal of this proposal is to establish innovative delivery technologies to maximize the efficiency of CRISPR delivery and gene correction in disease-relevant lung cell types. The impact of this project is a novel paradigm of lung-targeted delivery tools for CRISPR-mediated gene correction. The development of safe and effective delivery vehicles and genome editing tools will guide future studies for CRISPR-mediated gene therapy. This project has three aims that focus on different aspects of lung-directed somatic genome editing: Aim 1: Optimize NP+AAV combination for delivery and gene correction in mouse lung; Aim 2: Identify the best AAV capsid for lung delivery and optimize AAV genome as donor template for HDR; Aim 3: Characterize NP+AAV developed in the UG3 phase in macaque models. This project will develop innovative designs of adeno-associated virus and nanoparticles to significantly improve the efficiency, cell specificity, and safety of CRISPR delivery in vivo.

项目摘要体内纠正疾病基因突变的能力对于这两种疗法都具有广泛的潜在用途和基础研究。CRISPR/Cas9是一种强大的RNA指导的基因组编辑工具。我们最近发现CRISPR/Cas9递送可以治愈成年小鼠肝脏中的遗传疾病提供了体内基因校正疗法的概念验证。该提案的主要目标是建立创新的交付技术，以最大限度地提高CRISPR交付的效率，疾病相关肺细胞类型的基因校正。这个项目的影响是一部小说肺靶向递送工具的范例，用于CRISPR介导的基因校正。的开发安全有效的运载工具和基因组编辑工具将指导未来 CRISPR介导的基因治疗研究。该项目有三个目标，侧重于不同的目的1：优化NP+AAV组合，用于肺定向体细胞基因组编辑。目的2：鉴定用于肺的最佳AAV衣壳递送和优化AAV基因组作为HDR的供体模板;目标3：表征NP+AAV 在猕猴模型中的UG 3阶段开发。该项目将开发创新设计，腺相关病毒和纳米颗粒显著提高效率，细胞特异性，和CRISPR体内递送的安全性。
