The Immune System in Human Milk: A Historic Perspective

Area of Science:

• Immunology
• Human Lactation Biology

Background:

• Human milk possesses a complex system of immunological agents developed over millennia for infant protection.
• This protection extends beyond the breastfeeding period, offering lasting benefits to the child.

Observation:

• Pioneering scientists like Alfred François Donné, Paul Ehrlich, Lars Å. Hanson, and Jules Bordet made critical discoveries regarding human milk's immune components.
• Their work laid the groundwork for identifying numerous antimicrobial, anti-inflammatory, and immunomodulating agents in human milk.

Findings:

• Subsequent research revealed a wealth of bioactive factors and living leukocytes within human milk.
• Human milk actively promotes the colonization of beneficial commensal bacteria, further safeguarding the infant.

Implications:

• These discoveries have significantly contributed to the resurgence and support of breastfeeding in industrialized countries over recent decades.
• Acknowledging these scientists is crucial for understanding the historical development of human milk immunology.
