上个月段树民组在国际顶级期刊《NEURON》上发表封面文章:突触前Cdc42信号通路介导的沉默突触快速成熟机制研究,刚过去不到一个月的时间,又在《SCIENCE》上发表了胶质领域的有重要影响的文章。 英文摘要: Interactions between neurons and glial cells in the brain may serve important functions in the development, maintenance, and plasticity of neural circuits. Fast neuron-glia synaptic transmission has been found between hippocampal neurons and NG2 cells, a distinct population of macroglia-like cells widely distributed in the brain. We report that these neuron-glia synapses undergo activity-dependent modifications analogous to long-term potentiation (LTP) at excitatory synapses, a hallmark of neuronal plasticity. However, unlike the induction of LTP at many neuron-neuron synapses, both induction and expression of LTP at neuron-NG2 synapses involve Ca2+-permeable AMPA receptors on NG2 cells
