Overview
Inspiration and Background Research
Currently, LTF is used in a variety of dietary foods, supplements
and treatment products. However, the main method of production used
industrially today is extraction from secretory fluids of Bovine
animals. The optimal LTF for the consumption of human neonates would be
human LTF, but human LTF is rather difficult to obtain other than
extraction from human breast milk, and mass production using human
breast milk raises a series of moral issues. Recombinant production of
human LTF is beneficial to people needing the supplement after the end
of the breastfeeding period or the children of lactation disfunction
patients.
LTF
Lactotransferrin (LTF or Lactoferrin, LF), is aglobular glycoprotein
of the transferrin family with a molecular weight ofaround 80kDa(Sources
state 76-80kDa depending on glycosylation). LTF iscommonly found in
human (mammalian) secretory fluids, such as milk, tears,saliva and nasal
secretions. LTF is found most concentrated in colostrum. Incolostrum,
LTF acts alongside Immunoglobulins, lymphocytes, lysosomes,
lactoperoxidases and other bioactive substances to help the neonate
adapt to the non-sterile surroundings andestablish a healthy
gastrointestinal biome. LTF, as a kind of transferrinprotein, serves an
important purpose in iron regulation and transportation. Isolated
hololactoferrin has been used to treat iron deficiencies and anemia.
Lactoferrin has an important role in fueling immune health in infants
and children. Lactoferrin is a natural protein with multiple
physiological activities, which is involved in a variety of
pathophysiological processes such as regulating immune function,
anti-microbial, regulating iron absorption, and promoting intestinal
cell proliferation and differentiation. In recent years, lactoferrin has
been widely used in infants and young children, pregnant women and the
elderly, which can reduce the risk of infection in preterm infants, the
incidence of respiratory and gastrointestinal diseases in infants and
young children, improve anemia in infants and young children and
pregnant women, increase the rate of eradication of Helicobacter pylori
in children and adults, and improve immune function in the elderly.
