朱永群课题组以结构生物学为主要研究手段,结合生物化学、细胞生物学等实验方法,研究致病菌与宿主细胞相互作用以及基因组稳定性维持的分子机制。研究以革兰氏阴性致病菌如痢疾杆菌、致病性大肠杆菌和军团菌等为主要对象。革兰氏阴性致病菌通过特殊的分泌系统将毒性蛋白(又称效应蛋白)分泌到人宿主细胞中,分泌的效应蛋白作用于宿主细胞内特异的关键分子,从而调节宿主细胞的信号通路,达到有利于致病菌的侵染与繁殖的目的。因此,效应蛋白在致病菌致病过程中扮演着关键的角色。对效应蛋白及其作用机制进行深入的研究,将会促进人们对病原菌致病机理的了解,并且有可能为治疗相关传染疾病提供线索。另一方面,课题组也关注细胞如何维持基因组稳定性,以及由基因组不稳定性诱发的人类癌症发生的分子机制。当基因组DNA遭受由环境和化学因素引发的损伤时,细胞将启动DNA损伤反应机制,激活DNA damage checkpoint信号通路,停止细胞分裂,以及解开核小体的结构和募集下游DNA修复蛋白,对损伤的DNA进行识别与修复。DNA损伤反应机制的任何功能缺陷将会引起基因组的不稳定性,从而导致癌症的发生。课题组将研究DNA损伤与修复过程中核小体的变化过程以及DNA修复蛋白识别和修复损伤的DNA的分子机制,这将帮助我们找到相关癌症发生的原因。期望通过研究能够促进人们对威胁人类健康的两大威胁——传染性疾病与癌症的认识,并为相关的临床治疗提供宝贵的知识积累。
