Impaired leptin release
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 … WitrynaLeptin has emerged as a major regulator of adiposity. Leptin is released into the blood from fatcells and circulates to the brain where it crosses the bloodbrain barrier (BBB) to act at receptors within the central nervous system to affect appetite, thermogenesis, and a number of other actions.
