chemically modifying their cell-wall precursors. A synthetic cell-wall analogue was developed to hijack the biosynthetic rewiring of drug-resistant cells in response to antibiotics. Our study provides the first in vivo VanX reporter agent that responds to cell-wall alteration in drug-resistant bacteria. Cellular reporters that reveal mechanisms related to antibiotic resistance can potentially have a significant
耐药细菌感染的激增威胁着全世界医疗系统的负担。细菌细胞壁是细菌必不可少的,因此使其成为开发抗生素的独特靶标。我们描述了一个细胞记者,可以直接监测具有时间分辨率的耐药细菌中的表型转换。耐万古霉素的肠球菌(VRE)通过化学修饰其细胞壁前体来逃避万古霉素的杀菌作用。开发了一种合成的细胞壁类似物,以劫持耐药性细胞对抗生素的生物合成。我们的研究提供了第一种体内VanX报告剂,可对耐药菌中的细胞壁变化作出反应。
