刺胞动物是真核生物生命树中早期分支的动物。刺胞动物门分为五个纲：Scyphozoa（真水母），Cubozoa（箱水母），Hydrozoa（水螅和Hydractinia），Anthozoa（海葵，珊瑚和海笔）和Staurozoa（有柄水母）。多肽作为信号分子在刺胞动物的发育和分化中起着重要的作用。例如，刺胞动物利用肽进行细胞间通讯。最近的发现表明水螅神经肽控制几个生物过程，包括肌肉收缩，神经元分化和变态。在这里，我描述了水螅和其他刺胞动物的神经肽的结构和功能。本文还讨论了所谓的九头蛇原始神经系统比一般认为的要复杂得多。我还讨论了刺胞动物如何利用肽进行细胞间的通讯，而不是在高等动物。
Cnidarians are early-branching animals in the eukaryotic tree of life. The phylum Cnidaria are divided into five classes: Scyphozoa (true jellyfish), Cubozoa (box jellyfish), Hydrozoa (species, Hydra and Hydractinia), Anthozoa (sea anemone, corals, and sea pen), and Staurozoa (stalked jellyfish). Peptides play important roles as signaling molecules in development and differentiation in cnidaria. For example, cnidaria use peptides for cell-to cell communication. Recent discoveries show that Hydra neuropeptides control several biological processes including muscle contraction, neuron differentiation, and metamorphosis. Here, I describe the structure and functions of neuropeptides in Hydra and other cnidarian species. I also discuss that so-called primitive nervous system of Hydra is in more complex than generally believed. I also discuss how cnidaria use peptides for communication among cells rather than in higher animals.
