Beta-3 adrenergički receptor

edit

Beta-3 adrenergički receptor3 adrenoreceptor), takođe poznat kao ADRB3, je beta-adrenergički receptor. ADRB3 je takođe oznaka za ljudski gen koji ga kodira.[1]

Funkcija uredi

Dejstva β3 receptora obuhvataju:

Ova receptor je lociran uglavnom u adipoznom tkivu i učestvuje u regulaciji lipolize i termogeneze. Za neki β3 agoniste je utvrđeno da imaju antistresno dejstvo u studijama na životinjama. To sugestira da ovaj receptor takođe ima ulogu u CNS. Beta3-receptori su nađeni u žučnoj kesi, mokraćnoj bešiki, i u moždanom adipoznom tkivu. Njihova uloga u fiziologiji žučne kese je nepoznata, mada se smatra da učestvuju u lipolizi i termogenezi u smeđoj masnoći. Smatra se da u mokraćnoj bešiki izazivaju relaksaciju bešike i sprečavaju mokrenje.[4]

Mehanizam akcije uredi

Beta adrenergički receptori učestvuju u epinefrinom i norepinefrinom indukovanoj aktivaciji adenilat ciklaze putem aktivacije G proteina Gs tipa.[5]

Agonisti uredi

  • L-796,568[9]
  • CL-316,243[10]
  • LY-368,842
  • Ro40-2148

Selektivni β3 agonisti mogu potencijalno da pospeše umanjenje telesne težine putem modulacije lipolize.[2]

Antagonisti uredi

Interakcije uredi

Za beta-3 adrenergički receptor je pokazano da interaguje sa Src.[13]
