Lactoferrina
Sign in to saveAlso known as neutrophil lactoferrin, LTF, lactoferroxin, epididymis luminal protein 110, talalactoferrin, growth-inhibiting protein 12, kaliocin-1, lactoferrin
Lactoferrin (LF), also known as lactotransferrin (LTF), is a multifunctional protein of the transferrin family. Lactoferrin is a globular glycoprotein with a molecular mass of about 80 kDa that is widely represented in various secretory fluids, such as milk, saliva, tears, and nasal secretions. Lactoferrin is also present in secondary granules of PMNs and is secreted by some acinar cells. Lactoferrin can be purified from milk or produced recombinantly. Human colostrum ("first milk") has the highest concentration, followed by human milk, then cow milk (150 mg/L).

La lactoferrina, también conocida como lactotransferrina, es una proteína globular perteneciente a la familia de las transferrinas (transferrina, ovotransferrina, melanotransferrina, etc). Este grupo de proteínas muestra una gran afinidad por iones hierro. La lactoferrina es una proteína de defensa contra microorganismos presente en el lactosuero de la leche humana, donde se encuentra en una concentración relativamente elevada (1g/L), especialmente en la etapa calostral (hasta 7g/L). También se encuentra en la leche de yegua y en la de los rumiantes. En estos casos, es abundante en el calostro, pero solamente se mantienen concentraciones residuales bajas en la leche definitiva También está presente en otros fluidos corporales (lágrimas, semen, saliva, secreciones bronquiales, etc.). Es sintetizada por los neutrófilos de la sangre y por varios tipos de células incluyendo a algunas células acinares.
