Beta-1 adrenergički receptor (β₁ adrenoreceptor), ili ADRB1, je beta-adrenergički receptor. ADRB1 je takođe oznaka za ljudski gen koji ga kodira.^[1] On je G-protein spregnuti receptor koji vezuje Gs heterotrimerni G protein.

Receptor уреди

Dejstva уреди

Dejstva β₁ receptora obuhvataju:

stimuliše viskozne, amilazom-zasićene sekrecije pljuvačnih žlezda^[2]
Povećava srčani izlaz
- Povećava brzinu srca ^[3]
- Povećava kontraktilnost atrijalnog miokarda.
- Povećava kontraktilnost^[3] ventrikularnog miokarda.
- Povećava provođenje^[3] atrioventrikularnog čvora (AV čvor)
Oslobađanje renina iz jukstaglomerularnih ćelija^[3].
Lipoliza u adipoznom tkivu^[3].
Receptor je takođe prisutan u cerebralnom korteksu.

Agonisti уреди

Izoprenalin ima veći afinitet za β₁ od noradrenalina, koji se vezuje sa većim afinitetom od adrenalina. Selektivni agonisti beta-1 receptora su:

Antagonisti уреди

β1-selektivni antagonisti (Beta blokatori) su:

Acebutolol (u hipertenziji, angini pektoris i aritmijama)
Atenolol^[2] (u hipertenziji, koronarnoj arterijskoj bolesti, aritmijama i srčanom udaru)
Betaksolol (u hipertenziji i glaukomu)
Bisoprolol^[5] (u hipertenziji, koronarnoj arterijskoj bolesti, aritmijama, srčanom udaru i ishemijskom oboljenju srca)
Esmolol (aritmije)
Metoprolol^[2] (u hipertenziji, koronarnoj arterijskoj bolesti, srčanom udaru i srčanoj insuficijenciji)
Nebivolol (u hipertenziji)

Mehanizam уреди

G_s uzrokuje aktivaciju adenilat ciklaze, što dovodi do povećanja cAMP koncentracije.

Gen уреди

Ustanovljeno je da specifični polimorfizmi ovog gena utiču na brzinu rada srca i da mogu da imaju udela u srčanoj insuficijenciji.^[1]

Interakcije уреди

Za beta-1 adrenergički receptor je pokazano da interaguje sa DLG4^[6] i GIPC1.^[7]
