三部分突触是由神经胶质细胞与突触前和突触后成分的物理和功能相互作用定义的。虽然三方突触被认为在神经健康和疾病中具有广泛的重要性,但我们才刚刚开始了解神经胶质对突触功能的贡献。与神经元机制的研究相比,一个显著的限制是缺乏一个无脊椎动物遗传模型系统,在该模型系统中,可以通过大规模应用正向遗传学和全基因组遗传工具来研究三部分突触功能的保守机制。在这里,我们报道了一个果蝇三部分突触模型,它表现出与哺乳动物突触相似的形态和功能特性,包括细胞外谷氨酸的神经胶质调节,突触诱导的神经胶质钙瞬变以及突触与介导气体交换的气管结构的神经胶质偶联。结合果蝇的经典和细胞类型特异性遗传方法,该模型有望为三部分突触功能的分子和细胞机制提供新的见解。
Tripartite (three-part) synapses are defined by physical and functional interactions of glia with pre- and post-synaptic elements. Although tripartite synapses are thought to be of widespread importance in neurological health and disease, we are only beginning to develop an understanding of glial contributions to synaptic function. In contrast to studies of neuronal mechanisms, a significant limitation has been the lack of an invertebrate genetic model system in which conserved mechanisms of tripartite synapse function may be examined through large-scale application of forward genetics and genome-wide genetic tools. Here we report a Drosophila tripartite synapse model which exhibits morphological and functional properties similar to those of mammalian synapses, including glial regulation of extracellular glutamate, synaptically-induced glial calcium transients and glial coupling of synapses with tracheal structures mediating gas exchange. In combination with classical and cell-type specific genetic approaches in Drosophila, this model is expected to provide new insights into the molecular and cellular mechanisms of tripartite synapse function.
