摘要

发育过程中的轴突修剪受到促凋亡信号和抗凋亡信号之间谨慎平衡的控制，这些信号根据外部线索被激活，以形成成熟的神经元回路。在本期《科学信号》（Science Signaling）杂志上，亚伯拉罕等人定义了一种防止轴突修剪凋亡的保障措施，并说明Siah3能抑制Parkin介导的有丝分裂，从而控制激活修剪过程的轴突线粒体的可用性。

A Siah3 of relief: A role for mitophagy as a fail-safe during developmental axon pruning

Developmental axon pruning is controlled by a careful balance of pro- and anti-apoptotic signals, which are activated in response to external cues to sculpt mature neuronal circuitry. In this issue of Science Signaling, Abraham et al. define a safeguard against apoptotic axon pruning and illustrate that Siah3 represses Parkin-mediated mitophagy to control the availability of axonal mitochondria that activate the pruning process.
