抗生素耐药性的出现是细菌在所有环境中生存的令人难以置信的可塑性的一个例子。寻找对传统靶点有活性的新型抗生素更具挑战性,这不仅是因为缺乏新的天然产物来满足当前抗多药耐药(MDR)细菌的临床需求,而且还因为可能对人类微生物群产生“附带”影响。因此,提出了非传统的方法来对抗耐多药细菌。本文以肠球菌的三组分调控系统LiaFSR为模型,探讨了针对抗生素攻击的膜反应(细胞膜适应)作为一种可行策略的可能性,以增加当前抗菌剂的活性,增强先天免疫系统的活性,并在治疗过程中防止耐药性的发展。
Emergence of antibiotic resistance is an example of the incredible plasticity of bacteria to survive in all environments. The search for new antibiotics active against traditional targets is more challenging due not only to the lack of novel natural products to fulfill the current clinical needs against multidrug-resistant (MDR) bacteria, but also for the possible “collateral” effects on the human microbiota. Thus, non-traditional approaches to combat MDR bacteria have been proposed. Here, we discuss the possibility of targeting the membrane response to the antibiotic attack (cell membrane adaptation) as a viable strategy to increase the activity of current antimicrobials, enhance the activity of the innate immune system and prevent development of resistance during therapy using the three-component regulatory system LiaFSR of enterococci as a model.
