Participation of beta 2-receptors in the control of rabbit ciliary epithelial permeability

Current Eye Research
K Green, L Mayberry


The interaction between several adrenergic agonists (epinephrine, norepinephrine and isoproterenol) and relatively specific beta 1- and beta 2-antagonists has been examined on fluid permeability of the isolated rabbit ciliary epithelium. A specific beta 1-antagonist (metoprolol) had little effect on the permeability increase induced by the agonists, whereas butoxamine (a specific beta 2-antagonist) caused an inhibition of the normal agonist-induced permeability increase. The data suggest that these three adrenergic agonists primarily affect the beta 2-receptor in the ciliary epithelium in order to induce their effects on fluid permeability.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
