摘要:

细菌双组分系统(two-component system,TCS)是普遍存在于生物体内的信号转导通路,能够感知和响应细胞内外的物理、化学和生物刺激,通过耦合传感和调节机制引起一系列的细胞反应。TCS是细菌感知和响应环境信号、调节生理行为最主要的机制,在细菌耐药性、致病性、生物被膜形成、毒力因子调控等方面均发挥着重要作用。TCS通过两个组分(传感器和效应器)的相互作用来调控基因表达和细胞行为,从而应对不利环境对细菌的影响,以达到增殖和入侵宿主的目的。本文综述了双组分系统的结构、功能、耐药性和致病性研究进展及双组分系统抑制剂,以期为新型抗菌药物研发及细菌防控提供参考。

关键词: 双组分系统, 结构, 功能, 耐药性, 致病性

Abstract:

The bacterial two-component system (TCS) is a widespread signaling transduction pathway in organisms, which can sense and respond to physical, chemical, and biological stimuli inside and outside the cell, and induce a series of cellular responses through coupled sensing and regulatory mechanisms.TCS is the principal mechanism for bacteria to sense and respond to environmental signals and regulate physiological behaviors, which plays a crucial role in bacterial drug resistance, pathogenicity, biofilm formation, virulence factor regulation, etc.TCS regulates gene expression and cellular behaviors through the interactions of the two components (sensors and effectors) to handle the impact of adverse environment on bacteria, therefore achieving the goal of proliferation and invasion of the host.This paper reviews the research advances in the structure, function, drug resistance regulation and pathogenicity, and inhibitors of the two-component system, providing a reference for the development of novel antimicrobial drugs and bacterial prevention and control.

Key words: two-component system, structure, function, drug resistance, pathogenicity
