摘要 神经型钙粘素(N-cadherin)作为经典钙粘素家族的一员,是钙离子依赖的细胞连接中的一种重要跨膜成分,而其作为神经突触的粘附受体不仅为跨突触的细胞骨架提供了形式上的连接,还成为了功能上沟通突触前后膜的桥梁,传递粘附信号并调节突触的发育和成熟突触的可塑性。本文主要就后者讨论N-cadherin参与的成熟突触形态和功能的变化及调节中的新近进展,并试从粘附作用与信号传递两方面,分别从粘附作用的建立和调节,跨膜、跨突触,以及胞内信号传递,来分析N-cadherin对成熟突触的作用。可以看出,粘附是基础,信号传递是建立在其上的功能,并受粘附的调节。二者相互联系,协调作用。粘附的建立需通过信号传递与细胞骨架沟通,而粘附反过来又成为信号传递通路的起始信号,从而共同介导突触的形态和功能的变化及重塑。
