Abstract

Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), constitutes a major global health challenge. The pathogenesis of Mtb can be largely attributed to its sophisticated survival strategies within host macrophages. Methylglyoxal (MGO), a ubiquitous reactive dicarbonyl metabolite that spontaneously reacts with biopolymers forming advanced glycation end products (AGEs), togethers with reactive oxygen species (ROS) damage cellular events. The glyoxalase system serves as the primary metabolic pathway for MGO detoxification, mitigating carbonyl stress induced by excess MGO. The mycobacterial glyoxalase system likely functions as a vital defense mechanism against glycation and oxidative stress generated during pathogenic infection. Although extensive research has been conducted on the host glyoxalase system against diabetes, little is known about the mechanisms behind MGO detoxification in Mtb. This review aims at exploring the impact of MGO and its product AGEs on TB treatment and discussing the key molecular components, functions, and regulatory roles of the glyoxalase system in Mtb. Finally, we propose the utilization of mycobacterial glyoxalases as therapeutic targets for the development of anti-tuberculosis drugs.

甲基乙二醛解毒在结核分枝杆菌适应性和发病机制中的作用。
由结核分枝杆菌(Mtb)引起的结核病构成了一项重大的全球卫生挑战。结核分枝杆菌的发病机制很大程度上归因于其在宿主巨噬细胞内复杂的生存策略。甲基乙二醛(MGO)是一种普遍存在的活性二羰基代谢物,可与生物聚合物自发反应形成晚期糖基化终产物(AGEs),并与活性氧(ROS)一起损伤细胞事件。乙二醛酶系统作为MGO解毒的主要代谢途径,减轻过量MGO引起的羰基应激。分枝杆菌乙醛酶系统可能是一种重要的防御机制,可以抵抗致病性感染过程中产生的糖基化和氧化应激。尽管对宿主抗糖尿病的乙二醛酶系统进行了广泛的研究,但对Mtb中MGO解毒的机制知之甚少。本文旨在探讨MGO及其产物AGEs对结核治疗的影响,并讨论乙醛酶系统在结核中的关键分子成分、功能和调控作用。最后,我们提出利用分枝杆菌乙二醛酶作为抗结核药物的治疗靶点。
