翻译后修饰与结核分枝杆菌耐药调控网络

Post-translational modification and regulatory network of Mycobacterium tuberculosis antibiotic resistance

目前对于结核分枝杆菌(Mycobacterium tuberculosis,Mtb)耐药产生机制研究得较多,但对其调控机制的研究较少。翻译后修饰(Post-translational modifications,PTMs)在结核菌多种生理途径(如代谢、应激反应等)中发挥重要调控作用,而它们和结核菌耐药之间的关系逐渐引起了研究者的关注。文中介绍了结核菌抗生素耐受机制以及存在的一些PTMs,重点讨论了PTMs在调控结核杆菌耐药机制中的潜在作用,以期为新型抗结核药物研发提供新的切入点。

Currently, there are many studies on the mechanism of antibiotic resistance in Mycobacterium tuberculosis（Mtb）, but there are few studies on its regulatory mechanism. Post-translational modifications（PTMs） have been recognized for their important role in controlling cellular dynamics such as metabolism and stress response, but the relationship between PTMs and antibiotic resistance gradually attracted the attention of researchers. Here, we summarize the definition of PTMs, and the mechanisms of antibiotic resistance in M. tuberculosis and discuss how PTMs are involved in antibiotic resistance, in order to provide a new breakthrough for the development of new anti-Ttb drugs.
