我们回顾了关于发育中的小脑颗粒极性的研究,表明中心体定位于挤压新生轴突的神经元的极点,Rho GTPase Cdc42(细胞分裂周期42)激活mPar6alpha/Par3 (Par为分裂缺陷)复合体来协调生长锥中的肌动蛋白动力学。随后,mPar6alpha信号控制未成熟颗粒神经元沿伯格曼胶质纤维迁移到内部颗粒细胞层,并在其中建立突触连接。
We review studies on the polarity of developing cerebellar granule, showing that the centrosome localizes to the pole of the neuron that extrudes the nascent axon, and the Rho GTPase Cdc42 (cell division cycle 42) activates the mPar6alpha/Par3 (Par for partitioning defective) complex to coordinate actin dynamics in the growth cone. Subsequently, mPar6alpha signaling controls the migration of immature granule neurons down the Bergmann glial fibers into the internal granule cell layer in which they establish synaptic connections.
