Leptin -alerts the brain to turn off the hunger center and activates the satiety center when consuming a meal. Serotonin - affects motility and communicates with the brain for satiety. Cholecystokinin (CCK) - slows down stomach emptying to give a feeling of fullness (also increases bile production and release from gallbladder). A pharmaceutical company is interested in designing a drug to combat obesity. First, list 2 hormones involved in the regulation of hunger and satiety and state their function. Then, explain why the pharmaceutical would target these to treat obesity - Leptin alerts the brain to turn off the hunger center and activates the satiety center when consuming a meal. By sensitizing the patient to leptin or triggering it's activity in the brain, the patient would feel fuller and eat less. Ghrelin stimulates the hunger center as it deactivates the satiety center.
