3)研究领域:
细菌的群体行为及耐受性:自然状态的细菌常形成紧密聚集的群落,以生物被膜的形态存在。生物被膜广泛存在于我们生活中,并与人体健康息息相关。很多细菌感染都涉及到生物被膜。此外,生物被膜还常附着于医疗器械的表面,为公共健康带来极大的隐患。在群体状态下,细菌对药物及人体免疫系统有很强的耐受性。因此,生物被膜常导致持续性感染并难以根除。刘锦涛实验室运用多学科的理论和定量的研究方法,聚焦于对生物被膜的群体行为及其动态特性进行深入的研究,探索细菌群体中的新规律及其与人体健康的关系。
4)科学贡献:
首次发现了细菌间的相互合作与竞争导致生物被膜周期性减缓生长的新现象及其机制(Nature 2015, Science 2017);开发了定量研究细菌群体的新方法(Small Science 2022, Nature Chemical Biology 2023);揭示了细菌群体跨区域代谢交互的新模式(Nature Chemical Biology 2023);发现了细菌对抗生素以及噬菌体耐受性的新机制(Nature Chemical Biology 2024, Nature Communications 2024, Science Advances 2024)。
