发现细菌细胞膜上锚定的酶能在病毒基因组注入细胞时直接拦截并切割病毒DNA,揭示了细菌天然免疫系统的新防御机制

📝 英文原版摘要

<p>Nature, Published online: 18 March 2026; <a href="https://www.nature.com/articles/d41586-026-00732-4">doi:10.1038/d41586-026-00732-4</a></p>When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane intercepts and cleaves viral DNA during injection, providing a powerful form of antiviral defence.
