How does adrenergic agonist work
Webβ adrenergic receptors are coupled to a stimulatory G protein of adenylyl cyclase. This enzyme produces the second messenger cyclic adenosine monophosphate (cAMP). In the lung, cAMP decreases calcium concentrations within cells and activates protein kinase A. WebJun 10, 2024 · As you might already know, THC binds directly to the brain’s CB1 receptors, thereby triggering a “high” sensation. However, if you keep using high-THC strains within a short time, the body will try to reestablish homeostasis by blocking these THC molecules. Not only will CB1 receptors become “desensitized,” they may literally retreat.
