Witryna22 cze 2012 · Introduction. Leptin is an important mediator of pathophysiological outcomes in obesity. 1 Centrally, leptin plays an important role in maintaining energy homeostasis; therefore, the presence of high leptin in obesity has been suggested as evidence of resistance to central leptin actions. However, what is not clear is whether … Witryna26 lis 2024 · Leptin is an adipokine secreted in fat cells [ 6 ]. After leptin is released from the fat cell, it reaches the central nervous system via the blood, binds to its receptor, and reduces food intake through this receptor [ 7, 8 ]. Leptin is produced by the obese (ob) gene in adipose cells by encoding it into mRNA [ 9, 10 ].
