| Medications that can reduce androgen levels include estrogen, gonadotropin-releasing hormone agonists, and glucocorticoids. |
| Serotonin is a vasoconstrictor and uses agonists, such as ADP, epinephrine, and norepinephrine, to promote platelet aggregation. |
| The triptans are specific and selective serotonin agonists that block serotonin receptors and the resultant neurogenic inflammation. |
| These observations provide support for the model that glucose and structurally related sugars are agonists of the Gpr1 receptor. |
| The G-protein-coupled receptors sense various agonists such as photons, odorants, neurotransmitters, pheromones, and sugars. |
| Opioid receptor agonists act at sites that are distributed throughout this circuit to produce analgesia. |
