摘要在家蚕食道下神经节（SOG）中，有三个已知的神经分泌细胞群，它们表达一种编码中间停顿激素（DH）的基因和四种相关肽。长期慢性记录来自轴突束（NCC-3）的一对细胞定位在唇（后）神经节的SOG在蛹成发育。滞育产卵者和非滞育产卵者的唇神经分泌细胞的放电活动模式存在显著差异：前者的唇细胞在整个蛹-成虫发育过程中都处于活跃状态，而后者的唇细胞通常保持不活跃状态，直到蛹-成虫发育的最后四分之一，此时DH的分泌似乎太迟而不能作用于发育中的卵巢以诱导滞育卵。这一观察结果有力地支持了这一观点，即唇细胞释放DH，并负责决定胚胎滞育在家蚕。
Abstract There are three known clusters of neurosecretory cells expressing a gene encoding dia-pause hormone (DH) and four related peptides in the suboesophageal ganglion (SOG) of Bombyx mori. Long-term chronic recordings were made from the axonal tract (NCC-3) of a pair of cells localized in the labial (posterior) neuromere of SOG during pupal-adult development. There was a significant difference in firing activity patterns of the labial neurosecretory cells between diapause-egg and non-diapause-egg producers: labial cells in the former were active throughout pupal-adult development, whereas the same cells in the latter usually maintained an inactive state until the last quarter of pupal-adult development, a time at which a secretion of DH seems to be too late to act on the developing ovary for the induction of dia-pausing eggs. This observation strongly supports the notion that labial cells release DH and are responsible for determination of embryonic diapause in the silkmoth.
