The Multifaceted Functions of Lactoferrin in Antimicrobial Defense and Inflammation

Area of Science:

• Biochemistry
• Immunology
• Microbiology

Background:

• Lactoferrin (Lf) is an iron-binding glycoprotein in the transferrin family.
• It is abundant in secretions and neutrophil granules, playing a key role in innate immunity.

Purpose of the Study:

• To review the diverse biological functions of lactoferrin.
• To emphasize its roles in combating infections, modulating immunity, and regulating inflammation and oxidative stress.

Main Methods:

• Literature review of existing research on lactoferrin.
• Synthesis of findings on lactoferrin's mechanisms of action and therapeutic applications.

Main Results:

• Lactoferrin exhibits broad-spectrum antimicrobial activity through iron sequestration and membrane disruption.
• It modulates immune responses, reduces inflammation, and counteracts oxidative stress.
• Lactoferrin's functions are mediated by iron binding, direct microbial damage, and immune signaling.

Conclusions:

• Lactoferrin demonstrates significant therapeutic potential for infectious and inflammatory diseases.
• Its multifunctional properties make it a promising candidate for clinical applications in immune-related disorders.
• Further research can elucidate its full clinical utility.
