Talk:Beta-2 adrenergic receptor

Effect on Arteries of Skeletal Muscle
It doesn't say "dilates". I'm assuming an omission. Can anyone confirm that activation of beta-2 receptors dilates arteries to skeletal muscle? Horus (talk) 04:54, 27 October 2008 (UTC)

Clean up the introduction
the introduction isn't easy to read, e.g. instead of "ligand synonym adrenaline" use "epinephrine(adrenaline)". I have made small changes to it, I would be grateful for feedback.CaffeineWitcher (talk) 13:42, 17 May 2020 (UTC)

Link with Potassium channels
I stumbled upon a link between β2-adrenergic receptors and potassium channels.





It is relevant that it has a link with some medication inducing hypokalemia. (see the edits I did on that page.)

I just had not the time yet to understand the exact channels that are affected. If someone has more time and speed, it would be nice to add this info to wikipedia. Otherwise I will dig into the articles later. —Arthurfragoso (talk) 02:34, 4 June 2022 (UTC)

Relation to pH
Another thing I stumbled upon: This article that uses as source. It mentions the procedure carboxytherapy, and it says that when CO2 is infused, it lowers the lowers the local pH, and by doing so it would stimulate β2-adrenergic receptors bringing a local vasodilation. I was then wondering about how valid those claims are, unfortunately I can't access the source they use. But I found that suggest this receptor has a higher agonist activation at lower pH.

I immediately thought it could have a whole in the blood acid–base homeostasis, but as there isn't much articles covering β2AR pH relation, then maybe it doesn't have much impact or relevance on the acid–base homeostasis.

 * There is no hole in the principle of acid–base homeostasis. Since tissue is perfused with serum which in turn is also buffered, infusing carbon dioxide into tissue is not likely to change pH signficantly. I am highly skeptical that this treatment could activate β2-adrenergic receptors by changing pH. Boghog (talk) 18:30, 29 May 2023 (UTC)
