摘要: 随着畜牧业的飞速发展,集约化饲养、幼畜早期断奶策略应运而生,同时各种应激(如:热应激、冷应激、断奶应激、运输应激、氧化应激)增加,导致免疫系统还未完全建立的幼畜肠道损伤,严重时危及生命。miRNA是一类可调控基因表达的内源性非编码单链小分子RNA,是基因家族的重要成员,参与机体内部几乎所有的信号通路,能够调控肠上皮细胞的增殖与分化,介导肠黏膜屏障损伤。本文综述了应激对肠黏膜屏障功能的影响,miRNA对幼畜肠黏膜屏障功能的调控作用及可能作用途径。同时,综述了miRNA参与外源添加剂作用的模式,为营养素靶向干预调控幼畜肠道免疫功能提供理论依据,对提高幼畜培育具有重要意义。

Abstract: With the rapid development of animal husbandry, intensive feeding and early weaning strategy comes into being. At the same time, all kinds of stress (such as heat stress, cold stress, weaning stress, transport stress, oxidative stress) increase, resulting in intestine injury of young farm animals whose immune system has not been fully established, which is life-threatening in serious cases. miRNA is a kind of endogenous non-coding single-stranded small RNA, which can regulate gene expression. As an important member of the gene family, miRNA was involved in almost all the signaling pathways in the body. miRNA could regulate the proliferation and differentiation of intestinal epithelial cells and mediate intestinal mucosal barrier injury. This review summarized the effect of stress on intestinal mucosal barrier function, the regulatory role and possible pathways of miRNA on intestinal mucosal barrier function of young farm animals. At the same time, the mode of miRNA participating in the action of exogenous additives was reviewed to provide a theoretical basis for nutrients targeted intervention to regulate the intestinal immune function of young farm animals, and was of great significance to improve the breeding of young farm animals.

Key words: stress, miRNA, intestinal mucosal barrier
