乳铁蛋白(Lf)是一种在大多数生物体液中表达的铁结合糖蛋白,是哺乳动物先天免疫系统的主要组成部分。Lf的多种活性不仅依赖于其结合铁的能力,而且还与宿主和病原体的分子和细胞成分相互作用。Lf可以结合并隔离脂多糖(LPS),从而防止促炎途径激活、脓毒症和组织损伤。然而,LF结合的LPS可以保留通过Toll样受体4依赖性和非依赖性机制诱导细胞活化的能力。本文综述了Lf和LPS之间复杂的相互作用及其在免疫反应调节中的相关性。
Lactoferrin (Lf), an iron-binding glycoprotein expressed in most biological fluids, represents a major component of the mammalian innate immune system. Lf’s multiple activities rely not only on its capacity to bind iron, but also to interact with molecular and cellular components of both host and pathogens. Lf can bind and sequester lipopolysaccharide (LPS), thus preventing pro-inflammatory pathway activation, sepsis and tissue damage. However, Lf-bound LPS may retain the capacity to induce cell activation via Toll-like receptor 4-dependent and -independent mechanisms. This review discusses the complex interplay between Lf and LPS and its relevance in the regulation of the immune response.
