Beta-1 adrenergički receptor
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 | уреди извор]Dejstva
[уреди | уреди извор]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 | уреди извор]Izoprenalin ima veći afinitet za β1 od noradrenalina, koji se vezuje sa većim afinitetom od adrenalina. Selektivni agonisti beta-1 receptora su:
Antagonisti
[уреди | уреди извор]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 | уреди извор]Gs uzrokuje aktivaciju adenilat ciklaze, što dovodi do povećanja cAMP koncentracije.
Gen
[уреди | уреди извор]Ustanovljeno je da specifični polimorfizmi ovog gena utiču na brzinu rada srca i da mogu da imaju udela u srčanoj insuficijenciji.[1]
Interakcije
[уреди | уреди извор]Za beta-1 adrenergički receptor je pokazano da interaguje sa DLG4[6] i GIPC1.[7]
