Implication

Narrative review reveals how maternal microbial dysbiosis drives adverse pregnancy outcomes and shapes fetal programming, highlighting targetable immune, metabolic, and epigenetic pathways.

Key Points

Synthesize recent evidence on the spatial, temporal, and mechanistic links between maternal microbial communities, obstetric complications, and offspring health trajectories.
Conducted a narrative review synthesizing literature on niche-specific microbiome remodeling in the maternal gut, vagina, and oral cavity, as well as the placenta.
Evaluated molecular mechanisms linking microbial metabolites to maternal-fetal immune, metabolic, vascular, and epigenetic signaling pathways.
Maternal microbial dysbiosis drives adverse obstetric outcomes, including preterm birth, preeclampsia, and gestational diabetes, via pathways involving short-chain fatty acids, histamine, bile acids, and trimethylamine N-oxide.
Maternal microbes and their metabolic byproducts shape fetal and infant metabolic, immune, and neurodevelopmental trajectories through vertical transmission and epigenetic regulation.
