Cilia grow by assembling structural precursors delivered to their tips by intraflagellar transport. New work on ciliary length control indicates that, during ciliary growth, cilia send a length signal to the cytoplasm that regulates cargo loading onto the constitutively trafficking intraflagellar transport machinery.
纤毛通过组装由鞭毛内运输递送到其尖端的结构前体来生长。关于纤毛长度控制的新工作表明,在纤毛生长过程中,纤毛向细胞质发送长度信号,调节货物加载到组成型运输的鞭毛内运输机器上。
