棘皮动物神经肽的研究进展

Research Advances in Neuropeptides of Echinoderm

神经肽是神经系统最大、最多样化的一类信息分子,可调节动物的各种生理过程和行为。相较于脊椎动物和原口无脊椎动物,棘皮动物神经肽的研究起步较晚,而棘皮动物关键的分类地位和独特的生物学特征为其神经肽信号系统功能的研究提供了特殊背景。本文从神经肽分子的自身特性出发,对棘皮动物神经肽的作用方式、鉴定方法、功能调节及受体发掘等相关研究成果进行了综述,并对其未来的研究进行了展望。以期进一步解析神经肽在棘皮动物特殊生理行为调控中的作用机制,为棘皮动物中经济物种的高效绿色增养殖提供理论支撑。

Neuropeptides are the largest and the most diverse signaling molecules in the nerve system,which engage in regulating diverse physiological functions and behaviors of animals.Compared with well characterized vertebrates and protostomian invertebrates,studies on echinoderm neuropeptides are very limited.Key taxonomic status and unique biological characteristics of echinoderms provide particular insights for neuropeptide function resesrch.Here,based on the essence characteristics of neuropeptide,we discussed and looked forward to the relevant studies on the action mode,identification method,functional regulation and receptors discovery of echinoderm neuropeptides,hoping to inspire furture studies on regulation mechanism of neuropeptides in echinoderms'special physiological behaviors and provide theoretical support for the efficient and green aquiculture of economic species in echinoderms.
