Application
使用乳铁蛋白在铁限制培养基中培养变形链球菌。 用于测试乳铁蛋白在体外是否阻碍上皮细胞黏附 。 同时用于测试血液细胞因子浓度对急性肺炎的诊断价值。
Biochem/physiol Actions
乳铁蛋白是一种铁结合蛋白。在结构上与血浆铁转运蛋白转铁蛋白相似；但是乳铁蛋白对铁的亲和力要高得多（250 倍）。在初乳中含量非常丰富，少量也可见于泪液、唾液、粘液分泌物和中性粒细胞的次级颗粒中。由粘膜上皮和中性粒细胞组成，在炎症刺激下由这些细胞释放。细菌的生长被其隔离铁的能力所抑制，也通过其 N 端与脂多糖结合使细菌细胞壁通透性增加。乳铁蛋白可以通过与病毒包膜蛋白紧密结合来抑制病毒感染。这通过阻断结合域阻止了细胞与病毒的融合。乳铁蛋白似乎部分通过刺激中性粒细胞激活剂白细胞介素-8 的释放来激活宿主防御系统。还可能参与抗体和白细胞介素合成、淋巴细胞增殖和补体激活。

Lactoferrin (Lf), an iron-binding glycoprotein, has been shown to possess antioxidant and anti-inflammatory properties and exert modulatory effects on lipid homeostasis and non-alcoholic fatty liver disease (NAFLD), but our understanding of its regulatory mechanisms is limited and inconsistent. We used

Cancer cell-derived extracellular vesicles (EVs) are promising biomarkers for cancer diagnosis and prognosis. However, the lack of rapid and sensitive isolation techniques to obtain EVs from clinical samples at a sufficiently high yield limits their practicability. Chimeric nanocomposites of lactoferrin

The metalloprotease lethal factor (LF) from Bacillus anthracis plays a vital role in anthrax toxin action, and thus becomes a target for anti-anthrax therapy. Following the guidelines based on existing metalloprotease inhibitors, we designed a 'first-generation' LF inhibitor R9LF-1. This

The role of cytokines in the pathogenesis of pneumonia is still poorly understood. In a previous study the diagnostic value of measuring blood concentrations of interleukin 6 and interferon gamma was established. In the present study the value of blood

Melioidosis is an often-severe tropical infection caused by Burkholderia pseudomallei (Bp) with high associated morbidity and mortality. Burkholderia thailandensis (Bt) is a closely related surrogate that does not require BSL-3 conditions for study. Lactoferrin is an iron-binding glycoprotein that can
