研究方向:
主要来源于造血干细胞的免疫系统是维持机体健康的重要组成部分。相反,它的紊乱也是许多疾病过程的致病因素。我们实验室致力于进一步挖掘免疫系统特殊的调控机制、尝试人工改造免疫系统的新方法,期望可以对免疫相关疾病的治疗产生积极影响。实验室目前的工作主要可以分成两块:
- 针对免疫细胞的代谢学研究。机体在应激的状态下,会发生能量代谢的重排,旨在支持机体应对环境改变。作为机体应激的重要组成部分,免疫系统的功能必然与能量代谢有密切的联系。我们在这个逐渐兴起的领域开展了系列研究。我们的阶段性成果首次揭示了在抗病毒先天免疫激活条件下,巨噬细胞特异性的糖代谢重编程及其重要性(Jiang H et al., J Immunol 2016)。该研究带动了目前实验室中正在进行的一系列相关研究:如免疫代谢与自身免疫性疾病,以及与宏观代谢综合症(如II型糖尿病)的关联。
- 新一代顺式调控元件靶向技术在免疫学研究及细胞治疗中的应用。人类基因组中蕴藏着远远大于基因数目的顺式调控序列。这些序列在很大程度上决定各个基因在生理及病理条件下的表达,是基因之外控制生命活动的关键因素。最近,我们实验室与黄行许教授课题组合作,基于改造后的基因编辑平台(dCas9/sgRNA),率先在人源细胞中建立了高效、非突变型的顺式调控元件靶向技术(Du Y et al., Cell Res 2015)。我们正在进一步扩展顺式元件靶向技术在免疫系统中的应用。此外,我们在尝试利用类似的技术平台搭建人工转录调控回路,重新‘编排’细胞的免疫响应,为研发更加‘智能化’的细胞治疗提供基础。
