Neuropeptide Y (13-36), amide, human, is primarily studied for its role in modulating physiological processes, particularly in the central and peripheral nervous systems. It is a fragment of the full Neuropeptide Y (NPY) and retains some biological activities, making it valuable in research focused on understanding NPY receptor interactions. This peptide is often used in studies investigating its effects on appetite regulation, anxiety, and stress responses, as it interacts with Y2 receptors, which are implicated in these processes. Additionally, it serves as a tool to explore the therapeutic potential of NPY-related compounds in treating conditions like obesity, mood disorders, and cardiovascular diseases. Its application in pharmacological research helps in developing targeted therapies by elucidating the mechanisms of NPY signaling pathways.
