项目摘要

Abstract: Genome editing technologies have significant potential to treat a variety of devastating human diseases and disorders. However, there are a number of challenges that genome editing therapies must overcome to reach their full promise. Specifically, there are many possible adverse consequences that are unique to genome editing tools, such as genome integrity, immune responses, and loss of therapeutic efficacy due to cell turnover, for which there are currently are no optimal systems for rigorous assessment. Moreover, these consequences are unique to human physiology, genome sequence, and immune systems, and therefore typical animal models are not completely informative. To address this unmet need, we have assembled a team of collaborative investigators that have developed advanced genome editing strategies and methods for engineering human microphysiological tissue systems that recapitulate human physiology and function, with an emphasis on skeletal and cardiac muscle. We will combine these technologies in this proposal to systemically evaluate tissue physiology, genomic alterations, tissue regeneration, and immune response in response to various genome editing strategies and delivery methods. Specifically, this will include comprehensive and unbiased mapping of unintended modifications to human genome sequences, including at on-target and off-target sites. We will also determine the role of resident tissue stem cells, cell turnover, and tissue injury and regeneration in the stability of genome editing. Finally, we can incorporate immune cells into these microphysiological tissues to understand the consequences of immunity to bacteria-derived genome editing components. Collectively, this proposal will develop a platform to systematically address the most significant challenges to realizing the transformative potential of genome editing therapies in human tissues.

抽象的：基因组编辑技术具有处理各种毁灭性人类疾病的巨大潜力和疾病。但是，基因组编辑疗法必须克服的许多挑战才能达到他们的全部诺言。具体而言，基因组编辑独有的可能不良后果工具，例如基因组完整性，免疫反应以及由于细胞更新引起的治疗功效的丧失，用于目前没有进行严格评估的最佳系统。而且，这些后果是人类生理学，基因组序列和免疫系统独有，因此是典型的动物模型不完全有用。为了满足这种未满足的需求，我们组建了一个协作团队开发了高级基因组编辑策略和工程人工的方法的研究者概括人类生理学和功能的微生物生理组织系统，重点是骨骼和心肌。我们将将这些技术结合在该建议中以系统地评估组织生理学，基因组改变，组织再生和免疫反应对各种基因组的反应编辑策略和交付方法。具体而言，这将包括全面和公正的映射对人类基因组序列的意外修改，包括在目标和靶向位点。我们也会确定居民组织干细胞，细胞更新和组织损伤以及再生在稳定性中的作用基因组编辑。最后，我们可以将免疫细胞掺入这些微生物生理组织中以了解免疫对细菌衍生的基因组编辑成分的后果。总的来说，该提议将开发一个平台，以系统地解决实现变革性的最重大挑战基因组编辑疗法在人体组织中的潜力。
