Frontiers Role of Leptin in Cardiovascular Diseases

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. WitrynaThis, therefore, suggests that augmented synthesis of NO is likely to be antagonistic to the hypertensive effects of leptin-induced sympathetic stimulation. 22 Obesity causes endothelial dysfunction and impaired NO release; consequently, obese women with hyperleptinemia are more likely to suffer from hypertensive disorders such as PE, …
