后生动物生物体中许多不同细胞类型的发育和维持需要强大而多样的细胞间通讯机制。相对较少的这样的信号通路已被确定,导致这样一个广泛的多样性的输出是如何从相对简单的信号产生的问题。最近的研究揭示了整合时间和空间信息以产生信号通路输出多样性的复杂机制。我们回顾了一些信号通路的一般原则,重点是在果蝇的转录输出。我们认为不同的转导途径的空间和时间方面的作用,然后讨论最近开发的工具和方法是如何帮助解剖复杂的机制连接通路刺激输出。
The development and maintenance of the many different cell types in metazoan organisms requires robust and diverse intercellular communication mechanisms. Relatively few such signaling pathways have been identified, leading to the question of how such a broad diversity of output is generated from relatively simple signals. Recent studies have revealed complex mechanisms integrating temporal and spatial information to generate diversity in signaling pathway output. We review some general principles of signaling pathways, focusing on transcriptional outputs in Drosophila. We consider the role of spatial and temporal aspects of different transduction pathways and then discuss how recently developed tools and approaches are helping to dissect the complex mechanisms linking pathway stimulation to output.
