乳铁蛋白是哺乳动物体内具有多种生理功能的铁结合性糖蛋白。乳铁蛋白作用的靶细胞及细胞表面的特异性受体是其发挥多种生物功能的基础。本文主要介绍哺乳动物小肠乳铁蛋白受体的结构、结合特性和生理功能;阐述人和小鼠小肠乳铁蛋白受体的特性,及其促进铁离子吸收和调节机体免疫的功能。 相似文献

乳铁蛋白(Lactoferrin)是一种具有多种生理功能的天然多糖蛋白,由转铁蛋白转变而来,属于转铁蛋白家族,又称为乳转铁蛋白(Lactotransferrin)。1939年首次从牛乳中被分离发现,1960年首次从母乳中分离得到乳铁蛋白,随后科学家们在其它外分泌液中发现乳铁蛋白为主要的一种铁绑定蛋白质, 相似文献

Twenty-one Holstein calves (12 bulls, 9 heifers) were used to evaluate the effects of supplemental lactoferrin (0, 1, and 10 g/d) added to colostrum, milk, and milk replacer in a 56-d study. Calves fed lactoferrin (LF) weighed more during wk 2, 3, 4, 5, and 6 than control calves. Calves fed LF had increased preweaning daily weight gains and heart girth gains compared with calves not fed lactoferrin. Calves fed 1 g/d LF had a greater preweaning average daily gain than calves fed 10 g/d of lactoferrin. Hematocrit and serum Fe were unaffected by treatments. Calves were weaned when they had consumed 0.7 kg of calf starter grain for 2 consecutive d and were at least 28 d of age. All calves were weaned by 35 d of age, regardless of starter intake. Calves fed LF consumed more calf starter grain during the preweaning period and met weaning criteria at a younger age. This study indicates that supplementing calf diets with LF is advantageous to calf performance. 相似文献
