Human Milk Oligosaccharides: The Journey Ahead

Area of Science:

• Biochemistry
• Immunology
• Pediatrics

Background:

• Breast milk provides essential nutrients and bioactive agents for neonatal development.
• Human milk oligosaccharides (HMOs) are crucial glycans offering protection to newborns.
• HMOs influence the neonatal gut by acting as signaling molecules and interacting with host cells.

Purpose of the Study:

• To review the composition, structural diversity, and functions of HMOs.
• To discuss the impact of HMOs on newborn growth and survival.
• To identify current knowledge gaps and future research directions regarding HMOs.

Main Methods:

• Literature review of scientific articles on human milk oligosaccharides.
• Synthesis of information on HMO composition, structure, and biological activities.
• Analysis of the functional impact of HMOs on neonatal health and development.

Main Results:

• HMOs, despite limited nutritional value, exhibit significant prebiotic and immunomodulatory effects in the infant gut.
• Fucosylated and sialylated HMOs play vital roles in infant gut health.
• HMO quantity and quality vary based on maternal genetic and environmental factors.

Conclusions:

• HMOs are critical for neonatal health, influencing gut microbiota and immune responses.
• Understanding HMO heterogeneity is essential for optimizing infant nutrition and health outcomes.
• Further research is needed to fully elucidate HMO functions and therapeutic potential.
