乳铁蛋白(Iactoferrin)是一种存在于正常泪液中含铁的复合蛋白质,具有抑菌和杀菌二种特性,这就决定了它是患者外眼非特异性防御系统中的一个重要成份。最近Kijlstra等人证实,乳铁蛋白通过阻断补体C_3转化酶的形成对传统补体系统的激活有很强的抑制作用。这种能力表明,乳铁蛋白除了具有抗微生物的特性外,在抗炎症中亦有作用。
Lactoferrin, a complex iron-containing protein found in normal tear fluid, has two properties, bacteriostasis and bacteriostasis, which determine that it is an important component of the patient’s nonspecific defensive system. Recently Kijlstra et al. Demonstrated that lactoferrin strongly inhibits the activation of the traditional complement system by blocking the formation of the complement C_3 convertase. This ability suggests that lactoferrin has an anti-inflammatory effect in addition to its antimicrobial properties.
