Outline of Final Research Achievements

Glucagon-like peptide-1 (GLP-1) is one of gut hormones act as a satiety signal in the brain. However, circulating GLP-1 is unlikely to reach receptors in the brain because of its rapid metabolization in the blood. GLP-1 is also produced in a small population of cells in the brainstem. We propose that the GLP-1 releasing neurons play an important role in satiety and have started to characterize the relationship between satiety molecules (e.g. orexin, serotonin, and glucose), and the GLP-1 releasing neurons in the brainstem.
