The Maternal-Fetal Gut Microbiota Axis: Physiological Changes, Dietary Influence, and Modulation Possibilities

Area of Science:

• Microbiology
• Developmental Biology
• Immunology

Background:

• Early life development, including immune and central nervous system maturation, significantly impacts lifelong health.
• The establishment of the intestinal microbiota during prenatal and early postnatal periods is crucial for well-being.
• The maternal gut microbiota plays a key role in shaping the offspring's microbial community and subsequent health outcomes.

Purpose of the Study:

• To review the characteristics of maternal gut microbiota.
• To summarize the transmission routes of maternal microbiota to the offspring.
• To examine the influence of maternal diet and nutritional factors on the maternal-fetal microbiota axis and offspring health.

Main Methods:

• Literature review synthesizing current research on maternal gut microbiota.
• Analysis of studies investigating microbiota transmission from mother to child.
• Evaluation of research on dietary interventions during pregnancy and their effects on offspring microbiota.

Main Results:

• Maternal gut microbiota composition can be transmitted to the fetus and neonate.
• Dietary factors during pregnancy significantly modulate the maternal microbiota and the maternal-fetal microbiota axis.
• Alterations in the early-life microbiota are linked to various health issues in offspring.

Conclusions:

• The maternal gut microbiota is a critical factor in early development and long-term health.
• Maternal diet is a key modifiable factor influencing the offspring's microbiota and health trajectory.
• Further research into the maternal-fetal microbiota axis is essential for developing targeted nutritional strategies.
