Summary
This narrative review synthesises recent literature on milk-derived extracellular vesicles (nanovesicles carrying miRNA, DNA, RNA, proteins and lipids) and their potential roles in early child development. The authors conclude that whilst miRNA profiles in breast milk have been characterised across different mammalian sources, the actual effects on infant health remain incompletely understood and likely depend on maternal characteristics and environmental factors. The review suggests MDEVs may have significance for gut maturation, immune development and metabolic disease prevention, though evidence of clinical benefit remains preliminary.
UK applicability
The findings are relevant to UK maternal and infant nutrition policy and practice, particularly in understanding the bioactive composition of human milk and its role in early-life immune and metabolic programming. However, the review identifies significant knowledge gaps regarding actual health outcomes, which would require UK-based prospective studies to establish clinical relevance to infant feeding guidelines.
Key measures
miRNA cargo characterisation in milk-derived extracellular vesicles; expression profiles across mammalian milk sources; potential regulatory effects on gene expression, immune function and infant growth
Outcomes reported
The review characterised the miRNA cargo profile of milk-derived extracellular vesicles (MDEVs) across mammalian milk sources and evaluated their potential importance in regulating gene expression, immune function, development and infant growth. The authors synthesised evidence on how MDEVs may influence gut maturation, immune system development and prevention of metabolic disorders in infants.
