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 ]. WitrynaThe leptin receptor is turned on (activated) by a hormone called leptin that attaches (binds) to the receptor, fitting into it like a key into a lock. Normally, the body's fat cells …
