海胆早期血清素能神经系统的发育及功能研究进展

摘要

Sea urchin embryo is an ideal model for studying the neurodevelopment biology. Serotonergic nervous system (SNS) is the earliest one formed during the early development of sea urchin, which is comprised of the apical ganglion and serotonin receptor network. SNS is involved in regulating the swimming behavior of sea urchin larvae. In this study, we introduced the development process of apical ganglion and serotonin receptor network. The function of this nervous system was also summarized.%海胆胚胎是研究神经发育生物学的理想生物模型.血清素能神经系统在海胆早期胚胎发育过程中形成最早,主要由血清素能顶端神经节和受体细胞网络构成,对海胆幼虫的游泳行为具有调控功能.本文对海胆幼虫血清素能顶端神经节和受体细胞网络的发育过程,以及血清素能神经系统的功能等方面进行了综述.
