The emergence and spread of the African swine fever virus (ASFV) posed a significant threat to the global swine breeding industry, calling for innovative approaches benefiting viral containment and control. A recent study (Z. Zheng, L. Xu, H. Dou, Y. Zhou, X., et al., Microbiol Spectr 12: e02164-23, 2024, https://doi.org/10.1128/spectrum.02164-23) established a multiplexed CRISPR-Cas system targeting the genome of ASFV and tested the consequent antiviral activity both and . Application of this system showed a significant reduction of viral replication , while the germline-edited pigs expressing this system exhibited normal growth with continuous guide RNA expression. Although no survival advantage was observed upon ASFV challenge compared with nonengineered pigs, this marks the first attempt of germline editing to pursue ASFV resistance and paves the way for future disease-resistant animal breeding approaches utilizing CRISPR-Cas technology.
非洲猪瘟病毒(ASFV)的出现和传播对全球养猪业构成了重大威胁,需要创新的方法来控制和遏制病毒。最近的一项研究(Z. Zheng, L. Xu, H. Dou, Y. Zhou, X., et al., Microbiol Spectr 12: e02164-23, 2024, https://doi.org/10.1128/spectrum.02164-23)建立了一个针对 ASFV 基因组的多重 CRISPR-Cas 系统,并在 和 中测试了其随后的抗病毒活性。该系统的应用显著降低了病毒复制,而表达该系统的种系编辑猪在持续表达向导 RNA 的情况下表现出正常的生长。尽管与未经过基因编辑的猪相比,在 ASFV 攻毒后没有观察到生存优势,但这标志着首次利用种系编辑来追求 ASFV 抗性,并为未来利用 CRISPR-Cas 技术进行抗病动物养殖方法铺平了道路。
