Lactoferrin (Lf) is a protein with several functions of the transferrin family that is present in milk, saliva, tear and nasal secretions.

Lactoferrin is present in nature, purified from milk (human colostrum so called “first milk”, human milk and then cow milk) or produced in laboratory.

Lactoferrin is a components of the immune system and as such has many multiple physiological functions (anti-microbial, anti-inflammatory, and immunomodulatory): in particular it seems to block the entry of the virus into the cells: the union between the SARS-CoV-2 spike protein with its receptor (ACE-II receptors) would be prevented by Lf.

Thus, the treatment with Lf could be useful in this disease.
