Breastmilk and Immune Function

Area of Science:

• Immunology
• Neonatal Development
• Human Lactation

Background:

• Breast milk is vital for neonatal immune system development.
• It contains bioactive factors like extracellular vesicles, microRNA, and cytokines.
• These components enhance innate and adaptive immunity, protect against pathogens, and modulate inflammation.

Purpose of the Study:

• To summarize the immunological benefits of breast milk for infants.
• To highlight the mechanisms by which breast milk supports infant immune development.

Main Methods:

• Literature review of studies on human milk's immunological impact.
• Analysis of bioactive components in breast milk and their functions.
• Examination of the effects of breastfeeding on infant health outcomes.

Main Results:

• Human milk accelerates gut barrier maturation in neonates.
• Immune factors in breast milk protect infants from pathogenic damage.
• Breast milk components actively modulate inflammatory responses, reducing disease risk.

Conclusions:

• Breast milk significantly impacts infant immunological development.
• Breastfeeding should be promoted to support infant health.
• Exclusive breastfeeding for six months, followed by continued breastfeeding up to two years, is recommended.
