Leptin, the product the ob gene, is secreted by adipocytes to regulate energy homeostasis. This hormone may have an important influence on blood pressure, leading to hypertension. Leptin, acting in the hypothalamic melanocortin system, can activate or inactivate neuropeptides and produce hypertension, mainly by renal, adrenal, and muscular sympathoactivation. The role of leptin in regulating cardiovascular function in obesity is presented based on contemporary literature. Both intracellular signaling pathways activated by leptin and the role of leptin receptors are also discussed. The roles of endogens, neuropeptides in food intake, and energy expenditure are also presented.
瘦素是肥胖基因的产物,由脂肪细胞分泌以调节能量平衡。这种激素可能对血压产生重要影响,导致高血压。瘦素作用于下丘脑黑素皮质素系统,可激活或失活神经肽并主要通过肾、肾上腺和肌肉交感神经激活产生高血压。基于当代文献阐述了瘦素在肥胖中调节心血管功能的作用。还讨论了瘦素激活的细胞内信号通路以及瘦素受体的作用。也介绍了内源性物质、神经肽在食物摄入和能量消耗中的作用。
