Lachrymal Fluid (Tears)

A salty solution produced by the tear glands to bathe and lubricate the eye. Possesses antimicrobial properties.

Lactoferricin

A protein compound that acts to inhibit pathogenic (i.e., disease-causing) bacteria and yeasts (e.g., in the human body). See also Protein, Pathogen, Bacteria, Yeast, Lactoferrin.

Lactoferrin

A transferrin protein compound that is naturally produced in human breast milk. Also found within specific granules inside neutrophils/leukocytes and produced in cow’s milk. Lactoferrin assists transport of iron in the body, and it supports cell growth.

Consumption of lactoferrin by infants (e.g., via nursing) helps to strengthen their immune system. Consumption of lactoferrin by older humans helps their immune system to resist infectious diseases. Lactoferrin binds free iron (e.g., in body fluids), thereby denying that iron to pathogenic bacteria (which need that iron to grow/infect).

Pepsin and some other proteases (enzymes) can convert lactoferrin to lactoferricin. See also Protein, Cell, Pathogen, Bacteria, Growth (microbial), Lactoferricin, Pepsin, Protease, High-lactoferrin rice, Lactoperoxidase.
