5-HT6 receptor je tip 5-HT receptora za koji se vezuje endogeni neurotransmiter serotonin (5-hidroksitriptamin, 5-HT).[1] On je G protein-spregnuti receptor koji deluje kroz Gs/Go i posreduje ekscitatornu neurotransmisiju.[1] HTR6 je i oznaka za humani gen koji kodira ovaj receptor.[2]

Distribucija[уреди]

5-HT6 receptor je skoro isključivo izražen u mozgu.[3] On je distribuiran u više oblasti, među kojima su mirisne tuberkule, cerebralni korteks (frontalni i entorinalni regioni), nucleus accumbens, striatum, caudate nucleus, hipokampus, i mali mozak.[4][5][6] Usled njegove zastupljenosti u ekstrapiramidalnim, limbičnim, i korteksnim regionima smatra se da 5-HT6 receptor učestvuje u motornoj kontroli, emocionalnosti, kogniciji, i memoriji.[3][6][7]

Funkcija[уреди]

Za blokadu centralnih 5-HT6 receptora je pokazano da povišava glutamatergičku i holinergičku neurotransmisiju u više oblasti mozga,[8][9][10][11] dok aktivacija uvećava opštu GABA signalizaciju.[12] Antagonizam 5-HT6 receptora takođe omogućava otpuštanje dopamina i norepinefrina frontalnom korteksu,[11][13] dok stimulacija ima suprotni efekat.[12]

Ligandi[уреди]

Velik broj selektivnih 5-HT6 liganda je razvijen.[14][15][16][17][18][19][20]
