革兰氏阴性细菌的细胞膜是一个复杂的结构,其动态平衡对细菌的生存至关重要。包膜应激反应(ESRS)是一种信号转导通路,在正常生长过程中监控包膜组装的保真度,并检测和修复由外部攻击(包括免疫因子、蛋白质毒素和抗生素)造成的包膜损伤。在这篇综述中,我们重点介绍了三个研究最深入的ESRS,并讨论了ESRS检测包膜组装和完整性的各种扰动并调节包膜重塑以促进细菌生存的机制。我们将强调ESRS与包膜生物发生途径的复杂关系,并讨论该领域在绘制全球包膜动态平衡监管网络的道路上面临的一些挑战。
The Gram-negative bacterial cell envelope is a complex structure and its homeostasis is essential for bacterial survival. Envelope stress responses (ESRs) are signal transduction pathways that monitor the fidelity of envelope assembly during normal growth and also detect and repair envelope damage caused by external assaults, including immune factors, protein toxins, and antibiotics. In this review, we focus on three best-studied ESRs and discuss the mechanisms by which ESRs detect various perturbations of envelope assembly and integrity and regulate envelope remodeling to promote bacterial survival. We will highlight the complex relationship of ESRs with envelope biogenesis pathways and discuss some of the challenges in this field on the road to mapping the global regulatory network of envelope homeostasis.
