包括5-羟色胺和谷氨酸在内的几种神经递质已被证明参与神经发育的许多方面,除了它们在神经元通信中的公认作用之外,还参与神经突生长、神经元形态的调节、生长锥运动性和树突棘形状和密度。本文综述了近年来神经递质引起神经元形态学改变的分子机制的研究进展。在第一部分的审查,我们介绍了Rho家族的小GTP酶在神经元的形态发生信号的作用,并讨论信号通路,这可能会连接血清素,作为一个可溶性的指导因素,和Rho GTPases机械,控制神经元的形态和运动。在第二部分的审查,我们专注于谷氨酸诱导的神经可塑性和讨论的证据参与Rho和Ras GTP酶在功能和结构的突触可塑性谷氨酸受体激活触发。
Several neurotransmitters including serotonin and glutamate have been shown to be involved in many aspects of neural development, such as neurite outgrowth, regulation of neuronal morphology, growth cone motility and dendritic spine shape and density, in addition to their well-established role in neuronal communication. This review focuses on recent advances in our understanding of the molecular mechanisms underlying neurotransmitter-induced changes in neuronal morphology. In the first part of the review, we introduce the roles of small GTPases of the Rho family in morphogenic signaling in neurons and discuss signaling pathways, which may link serotonin, operating as a soluble guidance factor, and the Rho GTPase machinery, controlling neuronal morphology and motility. In the second part of the review, we focus on glutamate-induced neuroplasticity and discuss the evidence on involvement of Rho and Ras GTPases in functional and structural synaptic plasticity triggered by the activation of glutamate receptors.
