Construction of RABV Infection-related Key Host Factor Screening Method Based on Genome-wide CRISPR/Cas9 Library
摘要
Abstract
Rabies virus(RABV)is a highly lethal neurotropic virus that infect humans and warm-blooded animals and causes rabies,which currently has no effective treatment target.In order to comprehensively and efficiently explore the key host targets that mediate RABV infection,a screening method for RABV infection-dependent host factors was established using the CRISPR/Cas9 genome-wide library.In this study,CRISPR/Cas9 genome-wide knockout lentivirus was used to infect RABV-susceptible cells HEK-293,and the lentivirus-infected cells were cultured with puromycin to obtain a genome-wide knockout cell pool.The recombinant strain CVS11-eGFP carrying the green fluorescent reporter gene was used to infect the knockout cell pool,and the cells with extremely weak green fluorescence intensity were sorted by flow cytometry 48 hours later.The gene-edited cell clones KL-4 and KL-14 that were not infected with RABV were obtained after cell monoclonal culture and secondary infection with different RABV strains.In this study,a method was established to systematically screen the key host factors that mediated RABV infection using the CRISPR/Cas9 genome-wide knockout library,which provided new technical support for the discovery of key targets for rabies treatment in the host genome.关键词
