The wiring of the nervous system requires a complex orchestration of developmental events. Emerging evidence suggests that transient cell-cell interactions often serve as positional cues for axon guidance and synaptogenesis during the assembly of neural circuits. In contrast to the relatively stable cellular interactions between synaptic partners in mature circuits, these transient interactions involve cells that are not destined to be pre- or postsynaptic cells. Here we review the roles of these transient cell-cell interactions in a variety of developmental contexts and describe the mechanisms through which they organize neural connections.
神经系统的布线需要对发育事件进行复杂的协调。新出现的证据表明,在神经回路组装过程中,短暂的细胞间相互作用通常作为轴突导向和突触形成的位置线索。与成熟回路中突触伙伴之间相对稳定的细胞间相互作用不同,这些短暂的相互作用涉及并非注定成为突触前或突触后细胞的细胞。在这里,我们综述了这些短暂细胞间相互作用在各种发育背景下的作用,并描述了它们组织神经连接的机制。
