研究方向:

 

免疫学的中心问题之一是识别“我”和“非我”。作为适应性免疫重要的一部分,B细胞通过形成庞大的抗体库,以及在生发中心T细胞的帮助下,激发独有的体细胞超突变(somatic hypermutation),产生特异性抗体以识别和清除不断进化的病原微生物;另一方面,机体通过负向选择与自身抗原结合的B细胞保持对自身的耐受。通过长效抗体和记忆型B细胞形成的免疫记忆,机体可快速识别病原微生物的再次侵袭。

 

在感染性疾病或疫苗接种中,机体如何形成长效而广谱识别的抗体以应对不断进化的病原体?在自身免疫病中,致病性的自身抗体是如何形成的?可修饰的环境因素(如共生微生物)是否及如何影响免疫反应?围绕这些问题,我们实验室以B细胞介导的免疫学为中心,基于小鼠模型和人体纵向队列,结合分子生物学,生物化学,活体成像,细胞谱系追踪和生物信息学,对以下4个方面的研究特别有兴趣:

 

1. 感染或疫苗接种后机体的保护性免疫学机制

2. 自身免疫病中致病性自身抗体的形成机制

3. 共生微生物对免疫系统的调节

4. 中医药对免疫系统的调节
