Human Milk Extracellular Vesicles: A Biological System with Clinical Implications

Area of Science:

• Human milk composition and infant health.
• Extracellular vesicle biology.
• Maternal-fetal health communication.

Background:

• Human milk consumption is linked to infant health benefits, including reduced disease risk.
• Components like antibodies and oligosaccharides mediate these benefits.
• Human milk extracellular vesicles (hMEVs) are newly identified carriers of maternal information.

Purpose of the Study:

• To review the biogenesis and contents of hMEVs.
• To examine the functional role of hMEVs in maternal-infant health.
• To discuss current challenges and future research directions for hMEVs.

Main Methods:

• Literature review of existing studies on hMEVs.
• Analysis of hMEV cargo, including miRNAs and proteins.
• Synthesis of evidence on hMEV function in infant development.

Main Results:

• hMEVs contain functional molecules like miRNAs and proteins.
• Maternal health status impacts hMEV composition.
• hMEVs may play a crucial role in transmitting maternal information for infant growth.

Conclusions:

• hMEVs are significant mediators of maternal-infant health benefits.
• Further research is needed to understand hMEV mechanisms and therapeutic potential.
• Investigating hMEVs offers opportunities to enhance infant health strategies.
