Example text

The hydrophobic transmembrane segments (light color) are designated by Roman numerals (I–VII). The agonist (Ag) approaches the receptor from the extracellular fluid and binds to a site surrounded by the transmembrane regions of the receptor protein. G proteins interact with cytoplasmic regions of the receptor, especially with portions of the third cytoplasmic loop between transmembrane regions V and VI. The receptor’s cytoplasmic terminal tail contains numerous serine and threonine residues whose hydroxyl (-OH) groups can be phosphorylated.

This process effectively attenuates (rather than restores) cellular responsiveness, similar to the process of down-regulation described above for the epidermal growth factor receptor. Thus, depending on the particular receptor and duration of activation, endocytosis can contribute to either rapid recovery or prolonged attenuation of cellular responsiveness (Figure 2–12). Well-Established Second Messengers A. Cyclic Adenosine Monophosphate (cAMP) Acting as an intracellular second messenger, cAMP mediates such hormonal responses as the mobilization of stored energy (the breakdown of carbohydrates in liver or triglycerides in fat cells stimulated by β-adrenomimetic catecholamines), conservation of 2+ water by the kidney (mediated by vasopressin), Ca homeostasis (regulated by parathyroid hormone), and increased rate and contractile force of heart muscle (β-adrenomimetic catecholamines).

RELATION BETWEEN DRUG CONCENTRATION & RESPONSE The relation between dose of a drug and the clinically observed response may be complex. In carefully controlled in vitro systems, however, the relation between concentration of a drug and its effect is often simple and can be described with mathematical precision. This idealized relation underlies the more complex relations between dose and effect that occur when drugs are given to patients. Concentration-Effect Curves & Receptor Binding of Agonists Even in intact animals or patients, responses to low doses of a drug usually increase in direct proportion to dose.
