The PhoP-PhoQ two-component signal transduction system is an important signaling pathway in Shigella flexneri, which has been shown to control the virulence of Shigella flexneri. Therefore, this paper aims to study the mechanism of the PhoP-PhoQ two-component signal transduction system in regulating the virulence of Shigella flexneri.In this paper, we will first introduce and analyze the structure and function of the PhoP-PhoQ two-component signal transduction system. Then, we will discuss the role of the PhoP-PhoQ signal transduction pathway in regulating the virulence of Shigella flexneri. We will use a variety of experimental methods, including gene recombination, protein 精品文档---下载后可任意编辑purification, immunoblotting, fluorescent quantitative PCR, etc., to study the regulatory mechanism of the PhoP-PhoQ signal transduction pathway inside Shigella flexneri and its relationship with the virulence of Shigella flexneri.Due to the complexity and importance of the virulence regulation mechanism of Shigella flexneri, the results of this research have important theoretical and practical significance for understanding the pathophysiology of Shigella flexneri and the treatment and control of related diseases.Keywords: Shigella flexneri; PhoP-PhoQ two-component signal transduction system; virulence regulation; mechanism research
