ShortBiography:

Dahai Yang obtained his Ph.D. from East China University of Science and Technology (ECUST) in 2015. Prior to returning to China to assume an Assistant Professor at ECUST, he was a joint PhD student with Dr. Gabriel Núñez from the University of Michigan (2013-2015). In 2018, he was promoted to become an Associate Professor at ECUST. He awards the Young Elite Scientists Sponsorship Program, Shanghai Pujiang Program and Shanghai Chenguang Program. Dr. Yang’s research spans from bacterial pathogenesis to pyroptotic cell death and to septic-organ dysfunction. In mouse model, he has identified the Pannexin-1 and P2x7 receptor axis as the key substrates downstream of Caspase-11 during cytosolic LPSinfection in macrophages. In zebrafish model, he has uncovered the role of bacterial haemolysin in promoting outer membrane vesicles (OMV)-contained LPS releasing into cytosol to activate pyroptotic‐like cell death in non-phagocyte cells,and identified the zebrafish Caspy2 as the cytosolic pattern recognition receptor for LPS. His research is supported by grants from the National Natural Science Foundation of China and China Association for Science and Technology. 

Research Interests:

Dr. Dahai Yang’s group is interested in fundamental research in microbial-host interactions, innate immune responses, the pathogenesis of inflammatory disease. Specifically, the research focuses on mechanistic studies to understand the role of bacterial infection-induced pyroptosis in regulating multi-organ dysfunction during sepsis. Several approaches that include biochemical reconstitution, cell biology, analysis of genetically modified mutant mice, and zebrafish genetics to identify new components in pathogen-induced inflammasome activation and to further reveal the underlying biochemical mechanism involved in the interaction between microbial/endogenous molecules and sepsis.

研究概述:

  我们的研究兴趣集中在细菌感染激活细胞焦亡与脓毒症发生分子机制。以小鼠/斑马鱼为模型,从宿主抗感染天然免疫信号通路入手,致力于解析感染性多器官损伤/脓毒症的关键免疫机制,取得了一系列创新性进展:(1)鉴定了内毒素诱导巨噬细胞炎症性坏死信号通路的关键分子。采用内毒素转染巨噬细胞,建立了非经典炎症小体激活模型,阐明了炎症性Caspase底物Pannexin-1 和P2x7 受体信号在调控细胞焦亡过程中发挥的作用,为治疗革兰氏阴性细菌引发的脓毒症休克提供了新的理论支撑(Immunity 2015, 43: 923)。研究成果受到了Immunity的亮点评述和推荐,并在发表后受到了Nat Rev Immunol、Cell、F1000Research 等领域内重要综述引用报道130余次。(2)解析了细菌溶血素促进内毒素释放并激活非经典炎症小体分子机制。发现了溶血素促进细菌外膜囊泡携带LPS进入细胞质,激活非免疫细胞焦亡的分子机制(Cellular Microbiology 2019, e13010)。(3)以斑马鱼为模型,确定了模式识别演变中的关键事件。鉴定了细菌内毒素在斑马鱼中的胞内天然免疫受体Caspy2,解析了先天免疫中死亡结构域超家族介导细胞内LPS感应途径(Nature Communications 2018, 9: 3052)。(4)建立了斑马鱼脓毒症发生究模型。阐明了调控细胞焦亡信号调控脓毒症急性肾损伤发生的分子机制,为该疾病的靶向药物筛选提供了新的研究平台。上述研究工作对理解革兰氏阴性细菌感染的致病机理有极大的促进作用,获得的功能分子或病害防治靶标为感染引发的系统性疾病的免疫防控提供了新思路。

目前,我们对细菌感染激活细胞焦亡信号如何调控脓毒症多器官损伤的分子机制感兴趣,将结合流行病学、病原微生物学、生物化学、细胞生物学、以及小鼠和斑马鱼遗传学等多种手段来研究和解析细菌感染激活炎症小体引发细胞焦亡的分子机制,阐明其调控器官功能损伤、诱导感染性疾病发生的病理生理机制。\
