【摘要】 5-羟色胺(5-HT)和多巴胺(DA)是两种神经递质,可与众多不同类型的受体结合发挥多种重要的生理功能。现已证明其广泛分布于多种动物的不同组织中,在动物的打斗行为活动中起着重要的调节作用。目前,在虾蟹中已被报道的5-HT受体主要有5种,分别是5-HT1A、5-HT1B、5HT2A、5HT2B和5-HT7; DA受体主要为DA1A、DA1B、DA2和DA4。5-HT和DA及其受体分布存在明显的种属和组织特异性。5-HT和DA参于了虾蟹打斗行为的调节过程并有不同的调节机理。5-HT可以调节环磷酸腺苷(cAMP)或高血糖激素(CHH)的释放,促进或抑制虾蟹打斗行为;而DA同样能够通过调节cAMP及COMT等物质的释放来调节虾蟹打斗行为。更多还原

【Abstract】 Serotonin( 5-HT) and dopamine( DA) as neurotransmitters are important for many physiological functions by combining with different types of receptors. Both of them are widely distributed in different tissues of many animals,which play important role in agonistic behavior.There are five major 5-HT receptors( including 5-HT1 A,5-HT1 B,5 HT2 A,5 HT2 B and 5-HT7)and four receptors of dopamine( DA1 A,DA1 B,DA2 and DA4) in crustaceans. The distributions of 5-HT,DA and their receptors are species-and tissue-specific. In addition,5-HT and DA participate in the regulation of agonistic behavior of decapods crustaceans by different regulation mechanisms. 5-HT can regulate the release of cyclic adenosine monophosphate( cAMP) or hyperglycemic hormone( CHH),which can promote or inhibit the agonistic behavior in crustaceans. In contrast,dopamine could affect the agonistic behavior by mediating the release of cAMP and COMT.更多还原
