Obesity is a growing epidemic, causally associated with a number of serious medical conditions, including diabetes mellitus, coronary heart disease, and several cancers. The gut hormones ghrelin and peptide YY are secreted from the gut in response to changes to nutritional status. While food intake is stimulated by ghrelin, it is inhibited by peptide YY. The discovery, anatomy, and physiology of ghrelin and peptide YY are discussed, focusing on the adaptive changes in diseases such as obesity and anorexia nervosa. Ghrelin and PYY are important therapeutic targets in the quest to find an effective antiobesity treatment.
肥胖是一种日益普遍的流行病,与多种严重疾病存在因果关系,包括糖尿病、冠心病和几种癌症。肠道激素胃饥饿素和肽YY会根据营养状况的变化从肠道分泌出来。胃饥饿素会刺激食物摄入,而肽YY则会抑制食物摄入。本文讨论了胃饥饿素和肽YY的发现、解剖结构和生理学,重点关注肥胖症和神经性厌食症等疾病中的适应性变化。在寻找有效的抗肥胖治疗方法的过程中,胃饥饿素和肽YY是重要的治疗靶点。
