An antimicrobial peptide produced by epithelial cells in response to infection and inflammation. Part of the innate immune system's first line of defense. Research interest is growing for its potential in wound healing and anti-biofilm applications.
A naturally occurring iron-binding glycoprotein found in milk, saliva, tears, and mucosal secretions. One of the body's first-line innate immune defenses. Available as an oral supplement and in research-grade injectable form.
Disrupts microbial cell membranes through electrostatic interaction with negatively charged phospholipids. Also acts as a chemoattractant for dendritic cells and T-cells, bridging innate and adaptive immunity. Upregulated by IL-1β, TNF-α, and bacterial components.
Binds free iron, depriving bacteria of a nutrient essential for growth (bacteriostatic effect). Also directly disrupts bacterial cell membranes (bactericidal). Modulates immune response by promoting T-cell and NK cell activity while reducing inflammatory cytokines. Enhances iron absorption in the gut.
