五种经典神经递质在软体动物中的研究现状

通过对已有的研究资料分析发现，除了乙酰胆碱、谷氨酸、多巴胺、五羟色胺、1-氨基丁酸等一些经典神经递质之外，高等动物体内广泛存在的肾上腺素、去甲。肾上腺素等单胺类神经递质在软体动物体中却很少有研究资料报道；而软体动物神经系统中广泛存在的一些神经递质如章鱼胺、FMRF等在其他高等脊椎动物神经系统中也很少有报道。因此推测，在神经系统进化过程中，有些递质在后来的进化过程中一直保存下来，有些则被其他的类似物质替代。同时也有一些新型的神经递质形成而广泛存在于高等的脊椎动物中。本文对五种神经递质在软体动物中研究现状和发展趋势进行了讨论。

Research on the five neurotransmitter of the mollusk

Through analysis of existing research found that, in addition to acetylcholine, glutamate, dopamine, 5-hydroxytryplamine, γ-aminobutyric acid and other classical neurotransmitters, the adrenalin and noradrenalin were widely existence in vertebrate but not in the mollusc. By contrast, the octopamine and FMRF were widely existence in mollusk but not found in vertebrate CNS. Presume some transmitter was reserve in invertebrate and vertebrate, some was replaced with other analogue and generated some new transmitter in vertebrate in the last evolution of nervous system. The results suggested that the research of the five transmitter in the mollusk.
