摘要:

胰高血糖素样肽-2(GLP-2)是一条由33个氨基酸残基组成的短肽,主要由位于小肠的边缘和结肠中的L内分泌细胞分泌,与其受体(GLP-2R)结合激活一系列下游的反应来实现其功能。GLP-2具有促进肠道生长发育,修复受损伤肠道,加快营养物质转运与吸收,增强肠黏膜屏障功能等生理作用,目前GLP-2及GLP-2类似物([Gly-2]GLP-2)已被批准用于治疗短肠综合征等人类肠黏膜损伤性疾病。此外,由于GLP-2功能具有多样性,在畜牧生产上也有广阔的应用前景。如GLP-2可以用于家畜常见的一些肠胃炎的治疗,可用来缓解牛败血症引起的肺脏损伤,在维持肝脏健康方面也可发挥重要作用,还可作为一种厌食信号肽来增加食物在家畜中的转化率,以及用于缓解周围环境改变而引起的家畜不良应激反应,如热应激、缺水应激、氟中毒、饮食转换期间肠功能受损等问题。作者就GLP-2的最新研究进展及其在畜牧生产中的应用进行阐述。

Abstract:

Glucagon-like peptide-2(GLP-2) is a short peptide consisting of 33 amino acid residues and mainly secreted by L endocrine cells located in the small intestine edge and colon.GLP-2 can binds to its receptor GLP-2R to activate a series of downstream reactions to achieve its functions.It can promote intestinal growth and development,repair of damaged intestine,accelerate nutrient transport and absorption,and enhance intestinal mucosal barrier function.At present,GLP-2 and[Gly-2] GLP-2 have been approved for the treatment of human intestinal mucosal injury diseases such as short bowel syndrome.In addition,GLP-2 has a wide range of applications in livestock production because of its many functions.For example,GLP-2 can be used in the treatment of some common gastrointestinal inflammatory diseases in livestock.It can also alleviate lung injury caused by bovine sepsis and play an important role in maintaining liver health.Besides,as an anorexia signal peptide,GLP-2 can increases the conversion rate of food in livestock.GLP-2 is also used to relieve adverse environmental stress caused by changes in the surrounding environment,such as heat stress,water deficiency stress,fluorosis and intestinal dysfunction during diet switching and so on,In this paper,the latest research progress of GLP-2 and its application in animal production are discussed.
