FGF15 is a protein that belongs to the fibroblast growth factor family. It plays a crucial role in regulating various biological processes, including metabolism and cell growth. FGF15 is primarily produced in the intestines and is involved in signaling pathways that influence energy balance and fat metabolism. Research has shown that FGF15 can impact the body's response to dietary changes and may be linked to conditions such as obesity and diabetes. By understanding how FGF15 functions, scientists hope to develop new treatments for metabolic disorders and improve overall health.
