Laktoferryna

Laktoferryna is a globular glycoprotein also known as lactotransferrin. It is found in milk of mammals, including human breast milk, as well as in other bodily secretions like tears, saliva, and bile. Its primary function is to bind iron, which is essential for the growth of many microorganisms. By sequestering iron, laktoferryna can inhibit the proliferation of these bacteria and other pathogens, thus playing a role in innate immunity.

Beyond its iron-binding capabilities, laktoferryna possesses other biological activities. It exhibits antimicrobial properties through mechanisms other than iron chelation, such as direct damage to bacterial cell membranes. It also has anti-inflammatory and antioxidant effects. Laktoferryna is thought to contribute to the overall health benefits associated with breastfeeding.

In addition to its natural presence, laktoferryna is also available as a dietary supplement. It is sometimes used to support immune function, manage iron deficiency, and for its purported antimicrobial benefits. Research into its therapeutic potential is ongoing, with studies exploring its use in various conditions. The human body produces laktoferryna in the exocrine glands and in polymorphonuclear leukocytes.
