Ghrelin
Ghrelin is a hormone produced in the human body. It is produced and secreted by the P/D1 cells lining the fundus of the stomach. Ghrelin is classified as a peptide hormone.
Secretion and Production
Ghrelin is produced and secreted by the P/D1 cells lining the fundus of the stomach. The fundus of the stomach is responsible for stimulating appetite, and ghrelin seems to have a role in appetite control. In fact, ghrelin levels are higher in individuals of average weight than in obese individuals. Additionally, ghrelin stimulates the secretion of somatotropin from the anterior pituitary gland.
Pharmacological Uses
Ghrelin was first discovered in 1999. While a synthetic human form of ghrelin is not yet available, it is being researched, and its effects are being tested. Some of the potential medical uses of a ghrelin drug include obesity treatment and use as substitute for somatropin, the synthetic form of somatotropin. Additionally, some studies have shown that ghrelin may have some effect on learning and memory.
