甘丙肽是新近发现的一种神经肽,根据其分子结构分析来看,甘丙肽可能是区别

甘丙肽(galanin- GAL)是一种由29个氨基酸组成的神经肽,是神经肽的新成员,
是Tatomo
1 GAL 在神经系统的分布及其作用
1.1 GAL在中枢神经系统的分布及其作用
GAL广泛分布在中枢神经系统各个脑区.有人运用免疫组织化学和放射免疫测定法已经得到甘丙肽样免疫
1.2 GAL在周围神经和组织中的分布及其作用
有研究
2 GAL在消化中的分布及其作用
胃肠道含有GAL-LI的神经元,其胞体主要位于胃、十二指肠、回肠、结肠的肌层和粘膜下
2.1 食管: 有人在负鼠食管活体上进行研究发现,GA
2.2 胃: GAL对基础和刺激后的胃酸分泌均有抑制作
2.3 肠道: 含有GAL-LI的细胞主要位于小肠上段的
2.4 胰腺: Ch'ng首先报道,在猪和大鼠的胰腺内存
总之,GAL无论是对食管、胃、肠道平滑肌的收缩、胰腺分泌,还是对传入兴奋传导、垂体
