Neuropeptides and their Possible Role as Auxiliary Messengers

摘要: The communication by Elliott published in 1905 [1] dealing with the action of adrenaline peripheral tissues has often been considered to represent first evidence that neurons communicate effector cells periphery and other via chemical messengers [see book edited Stjarne et al. (2)]. With regard compounds involved transmission, focus since then on a fairly small number compounds, including catecholamines such as dopamine, noradrenaline adrenaline, well 5-hydroxytryptamine (5-HT), acetylcholine, more recently group amino acids, for example glutamate y-aminobutyric acid (GABA). More recent suggests also certain peptides may be present may, fact, transmission processes at synapses 3 4], inclusion peptides, putative transmitters nervous system increased dramatically 4].
