Genome and proteome data from Hydra magnipapillata have opened the way for the molecular analysis of an ancient nervous system, which includes stinging cells, an unusual neurosensory and neurosecretory cell type. They hold some surprises for the mechanisms and evolution of sensory transduction that could not have been anticipated from what has been learned from flies and vertebrates. Research in BMC Biology now implicates the ancient opsin-mediated transduction pathway in the neuronal control of stinging cell discharge.
水螅巨肠藻的基因组和蛋白质组数据为古老神经系统的分子分析开辟了道路，其中包括刺细胞、一种不寻常的神经感觉和神经分泌细胞类型。它们为感觉转导的机制和进化提供了一些惊喜，这些惊喜是无法从从苍蝇和脊椎动物中学到的知识中预测到的。BMC 生物学的研究现在表明，古老的视蛋白介导的转导途径参与了神经元对刺细胞放电的控制。
