Neurotransmitter Receptor Type Locatie/Functies Aanvullende informatie

Acetylcholine (ACh) Nicotinerge receptoren Ionotroop - Snelle synaptische Ligand-gated ionkanaal;
(nAChR) transmissie laat Na⁺ en K⁺ door

- neuromusculair Nm - Corticale activering en
- neuronaal Nn motoriek

Muscarinerge Metabotroop - Aandacht, geheugen, G-eiwit-gekoppelde
receptoren (mAChR) parasympathische regulatie receptor
5 subtypes (M1-M5) 2nd m: cAMP & IP3

Noradrenaline (NA) α1-adrenerge Metabotroop - Vasoconstrictie Activeren fosfolipase C via
receptoren Gq-eiwitten
- controle gladde spiercellen
postsynaptisch Daling K-concentratie

α2-adrenerge Metabotroop - vasoconstrictie Gi-eiwit-gekoppeld; remt
receptoren cAMP-productie Stijging K-
concentratie, daling Ca-
presynaptisch
concentratie

β1-adrenerge Metabotroop - Hartslagverhoging Gs-eiwit-gekoppeld;
receptoren verhoogt cAMP-productie

Daling K-concentratie

β2-adrenerge Metabotroop - Bronchodilatatie Gs-eiwit-gekoppeld
receptoren
- vasodilatatie

Dopamine (DA) D1-receptoren (D1&D5) Metabotroop - Excitatoire effecten Gs-eiwit-gekoppeld;
verhoogt cAMP-productie
- Regulatie beloning en
motoriek D1 in striatum

D2-receptoren Metabotroop - Inhibitoire effecten Gi-eiwit-gekoppeld;
(D2,D3&D4) verlaagt cAMP-productie
- Autoregulatie en
verslavingsgedrag D2 in striatum, D3 in
nucleus accumens

Serotonine (5-HT) 5-HT1-receptoren Metabotroop - Regulatie stemming, angst, Gi-eiwit-gekoppeld;
(Dia 3 voor subtypes) thermoregulatie verlaagt cAMP-productie

5-HT2-receptoren Metabotroop - Perceptie, hallucinaties Gq-eiwit-gekoppeld;
verhoogt intracellulaire
calcium

5-HT3-receptoren Ionotroop - Braakreflex- Misselijkheid Ligand-gated ionkanaal;
laat Na⁺ en K⁺ door

5-HT6/7-receptoren Metabotroop - limbisch systeem: gemoed Gi-eiwit-gekoppeld;
en stemming verhoogt cAMP-productie

Histamine (H) H1-receptoren Metabotroop - Regulatie waakzaamheid Gq-eiwit-gekoppeld;
en allergische reacties betrokken bij slaap-
waakcyclus en
- arousal
immuunreacties
- feeding/
Link met werkgeheugen
energiemetabolisme
