个人简介

巴钊庆博士北京生命科学研究所研究员教育经历 2013年北京生命科学研究所与北京师范大学联合培养生物化学与分子生物学博士 Ph.D. in Biochemistry and Molecular Biology, National Institute of Biological Science (NIBS), Beijing & Beijing Normal University, Beijing, China 2008年江南大学生物工程基地班学士 B.S. in Biotechnology (National Base of Life Science & Biotechnology Education Program), Jiangnan University, Wuxi, Jiangsu, China 2021年- 北京生命科学研究所研究员 Assistant Investigator, National Institute of Biological Sciences, Beijing, China 2019-2021年哈佛医学院/波士顿儿童医院讲师/副研究员 Instructor/Research Associate, Harvard Medical School/Boston Children’s Hospital, Boston, USA 2014-2019 年哈佛医学院/波士顿儿童医院博士后 Postdoctoral Research Fellow, Harvard Medical School/Boston Children’s Hospital, Boston, USA 2013-2014 年清华大学生命科学学院博士后 Postdoctoral Research Fellow, Tsinghua University, Beijing, China B 淋巴细胞作为适应性免疫系统关键组分之一对机体抵御病原体感染和疾病侵袭至关重要。B 细胞在分化和抗原激活过程中受到精细调控从而在特定时空以“特异性”和“多样性”方式生成抗体,从而使机体能够“适应性”应对纷繁复杂的抗原世界。此外,B 细胞还具有形成高级淋巴结构、重塑T细胞反应、呈递抗原和分泌细胞因子等功能而广泛参与慢性感染、自身免疫、异体移植、组织稳态及肿瘤免疫等过程。B细胞异常导致诸多免疫相关和肿瘤疾病。因此，深入研究B细胞分化和功能调控具有多方面重要意义。然而,囿于B 细胞调控的复杂性和研究手段的局限性,我们对其理解仍不清楚。我们前期通过开发和利用一系列基于高通量测序的新方法系统揭示了小鼠抗体编码基因多样化重排的分子机制,为领域内长期存在的问题提供了新的见解;我们还开发了快速生成 B 淋巴癌小鼠模型的新技术,提供了一种快速生成包括肿瘤免疫研究必需的小鼠疾病模型的通用新方法。未来，我们将继续通过开发和利用新技术在个体、器官组织、细胞、分子多尺度下深入研究 B 细胞分化和功能调控、抗体特异性和多样性塑造机制以及 B 细胞缺陷相关免疫疾病和肿瘤的病理。我们期望通过这些研究最终建立新型高效的疫苗和治疗性抗体的开发平台以及研发能够治疗相关免疫疾病和肿瘤的创新性药物。 Invited Review and Book Chapter 1.
