| 摘 要： | 【摘要】 群体感应系统是一种依赖于群体密度变化的细胞间通讯方式,与皮肤菌群的变化及致病性密切相关。金黄色葡萄球菌致病毒力因子的合成受辅助基因调节（Agr）群体感应系统调控。各类皮肤共生菌如凝固酶阴性葡萄球菌、棒状杆菌属可通过抑制金黄色葡萄球菌的Agr群体感应系统,抑制毒力因子合成,减轻皮肤炎症。本文综述微生物群体感应系统在皮肤炎症中的作用机制及各类群体感应抑制剂。

| Abstract: | 【Abstract】 Quorum-sensing system is a way of communication between cells that depends on changes in population density of microorganisms, and is closely associated with variety and pathogenicity of skin microbiota. The synthesis of virulence factors of Staphylococcus aureus （S. aureus） is regulated by the accessory gene regulator （Agr） quorum-sensing system. Various skin commensals such as coagulase-negative Staphylococcus and Corynebacterium can inhibit the Agr quorum-sensing system of S. aureus, thus decrease the synthesis of virulence factors and attenuate skin inflammation. This review summarizes the mechanism of action of microbial quorum-sensing system in skin inflammation and various quorum-sensing inhibitors. |
