Adrenergic Receptor #

Noradrenaline binds to them, idk when it gets methylated to Adrenaline

  • α1: Gq
    • Smooth muscle contraction of blood vessels, ureter, ductus deferens, and internal urethral sphincter.
    • Liver: glycogenolysis
    • Adipose tissue: Gluconeogenesis
    • Sweat gland secretion
    • α1A
    • α1B
    • α1C
    • α1D
  • α2 Adrenergic Receptor: Gi
  • β1: Gs. Anxiolytic. Expressed in the heart.
  • β2: Gs and Gi. Relaxation of the bladder. Lipolysis/thermogenesis in Brown Adipose. Found in muscle tissue moreso than the other β receptors.
  • β3 Adrenegic Receptor: Gs and Gi. Shit’s complicated. Expressed in the bladder.
    • β3 agonism = relaxation of the bladder = peeing less, but a lot when you do.
