本文讨论了低浓度环丙沙星促进大肠杆菌分化出两个亚群,通过膜囊泡转移蛋白质和信号分子,增加受体细胞存活率的研究。
原文开头
Low concentrations of the antibiotic ciprofloxacin promote the differentiation of two subpopulations of Escherichia coli bacteria within a population of cells with the same genes. The two subpopulations are characterized by differential expression of HipA, which is regulated by HipB. Cells with low HipA concentrations express PspA, which promotes the formation of membrane vesicles that carry proteins and signaling molecules. The recipient cells are characterized by high HipA and low PspA concentrations. Uptake of membrane vesicles increases the survival of recipient cells. bolic enzymes, ribosomal proteins, DNA repair proteins, and inner and outer membrane proteins. Which of these factors contribute to antibiotic survival after transfer into recipient cells and how they do so remain to be determined. …
