Publication number: 20230193256Abstract: A system and method for gene editing by using an engineered cell are provided. The system includes the engineered cell embedded with a synthetic protein receptor and a target cell. The engineered cell contains a CRISPR/CasRx system and a sgRNA gene sequence. The synthetic protein receptor includes an extracellular target cell recognition domain, a native Notch core domain, an intramembranous hydrolyzable polypeptide and effectors. The extracellular target cell recognition domain can recognize antigen molecules on the target cell surface; and the effectors act as transcription factors for CasRx enzyme and sgRNAs. CasRx and gRNA are expressed in the engineered cell for gene editing to edit mRNA of the target cell. In this way, the application range of the engineered cell is expanded, the pertinence and specificity of gene editing are improved, the off-target effect is reduced, the collective non-specific reaction is reduced, and the safety of gene editing is improved.Type: ApplicationFiled: August 22, 2022Publication date: June 22, 2023Applicants: Huashan Hospital, Fudan UniversityInventors: Jianhong ZHU, Tianwen LI, Kezhu CHEN
