Bacteria have evolved anti-viral defenses, but the mechanisms of sensing and stopping infection are still under investigation. In this issue of Cell Host & Microbe, Mets, Kurata, Ernits et al. describe how direct sensing of a phage protein by a bacterial toxin-antitoxin-associated chaperone unleashes toxin activity to prevent infection.

伴侣帮助应对噬菌体感染

细菌已经进化出了抗病毒防御能力，但感知和阻止感染的机制仍在研究中。在本期《细胞宿主与微生物》中，Mets、Kurata、Ernits 等人。描述细菌毒素-抗毒素相关伴侣直接感知噬菌体蛋白如何释放毒素活性以预防感染。
