Muskarinski acetilholinski receptor M4 (muskarinski holinergijski receptor 4, CHRM4), je protein koji je kod ljudi kodiran CHRM4 genom.[1][2]

Funkcije

Muskarinski acetilholinski receptori pripadaju velikoj familiji G protein spregnutih receptora. Funkcionalna raznovrsnost ovih receptora je definisana vezivanjem acetilholina, i obuhvata ćelijske odgovore poput inhibicije adenilat ciklaze, fosfoinozitidne degeneracije i modulacije kalijumovih kanala. Muskarinski receptori posreduju mnoge efekte acetilholina u centralnom i perifernom nervnom sistemu. Klinički značaj ovoj receptora nije poznat; međutim, studije na miševima su ustanovile vezu između njegovog dejstva i inhibicije adenilil ciklaze.[1]

M4 muskarinski receptori deluju kao inhibitorni autoreceptori za acetilholin. Aktivacija M4 receptora inhibira oslobađanje acetilholina u striatumu. M2 podtip acetilholinksog receptora deluje na sličan način, kao inhibitorni autoreceptor acetilholinskog otpuštanja, mada taj receptor deluje prvenstveno u hipokampusu i cerebralnom korteksu.

Muskarinski acetilholinski receptori imaju regulatorno dejstvo na dopaminergijsku neurotransmisiju. Aktivacija M4 receptora u striatumu inhibira D1-indukovanu lokomotornu stimulaciju kod miševa. Miševi koji su deficitarni u M4 receptorima ispoljavaju povećanu lokomotornu stimulaciju u odgovoru na D1 agoniste, amfetamin i kokain.[3][4][5] Neurotransmisija u striatumu utiče na ekstrapiramidalnu motornu kontrolu, tako da alteracije M4 aktivnosti mogu da doprinosu oboljenjima poput Parkinsonove bolesti.[6][7][8]
