Structura synapsis typicae

Neurotransmissor (-oris, m.) sive neurotransmittens[1] est substantia biochemica endogena quae signa ex neurono ad cellulam destinatam per synapsem transmittit.[2] Neurotransmissores in vesiculas synapticas colliguntur quae sub lateris praesynaptici membrana synaptica congregatae sunt, et in fissuram synapticam solvuntur, ubi ad receptoria alligantur quae in lateris postsynaptici membrana synaptica insunt.

Subclasses[recensere | fontem recensere]

Neurotransmissores in tria subclasses dividi possunt: acidorum aminicorum, peptidorum, monoaminorum. Magni transmissores sunt:

  • Acidi aminici: Glutamatum, Aspartatum, D-Serinum, γ-Aminobutyratum (GABA), Glycinum
  • Gasotransmissores: Nitrogenii oxidum (NO), Carbonii monoxidum, Hydrogenii sulphidum
  • Monoamini: Dopaminum (DA), Noradrenalinum (NA, NE), Adrenalinum, Histaminum, Serotoninum (5-HT)
  • Oligoamini[3]: Phenethylaminum, N-Methylphenethylaminum, Tyraminum, 3-Iodothyronaminum, Octopaminum, Synephrinum, Tryptaminum
  • Peptidi: Somatostatinum, Substantia P, CART[4], peptidi opioidi
  • Purini: Adenosini triphosphatum (ATP), Adenosinum
  • Alii: Acetylcholinum (ACh), Anandamidum
