神经激素肽类(调节肽类)是由内分泌/旁分泌(paracrine)细胞和在中枢及周围神经系统内的神经元产生,因为这些信息细胞参与调控周围组织的功能,曾认为它们构成了一个功能上联合的通讯网络,称之为神经内分泌系统。许多实验结果支持了这种一元化的观念,由此提示神经元及产生多肽的内分泌/旁分泌细胞具有共同的遗传编码。因此,几种调节肽类双重分布在内分泌细胞
Neurohormonal peptides (regulatory peptides) are produced by endocrine / paracrine cells and neurons in the central and peripheral nervous systems because these information cells are involved in the regulation of the function of the surrounding tissues and have been considered as constituting a function The joint communications network, called the neuroendocrine system. Many experimental results support this monolithic notion, suggesting that neurons and endocrine / paracrine cells that produce the polypeptide have a common genetic code. Therefore, several regulatory peptides are dually distributed in endocrine cells
