研究领域
大脑通过约1015个突触连接而成的巨大通讯网络来进行信息处理、行使功能。突触通过自身的可塑性,传递、转变和完善信号。突触细胞粘附因子,通过连接突触前、后细胞,调节突触传递信号,并且通过形成特异性的突触功能来决定神经网络的特性。家系分析发现,人类突触细胞粘附因子基因发生突变与孤独症、精神分裂症等关联;基因组水平研究显示,包括孤独症、精神分裂症等多种认知性疾病,均存在编码突触分子,如Caherins、Protocadherins、L1CAM、Neuroligin、Neurexin、CNTNAP2和Contactins等的基因异常,但其致病机制不清。本研究组以神经元表面蛋白分子为研究对象,应用遗传学、分子生物学等手段,结合模式生物,研究它们在突触发生、成熟、可塑性以及在学习记忆等高级神经活动与行为中的作用,探讨其在遗传和表观遗传水平上的调控机制,为阐明其在相关的认知障碍与疾病中的作用奠定基础。
