Summary: Studies show that the fetal gut is not sterile and contains a low abundance but metabolically rich microbiome, with Proteobacteria and Actinobacteria as the dominant phyla. The presence of microbes in the fetal gut provides support for the study of early fetal immunity. This study also explores the specific composition of viruses in the fetal gut and the similarities between fetal and adults' gut microbiota, which is valuable for understanding human fetal immunity development during gestation.

Summary: The maternal microbiome plays a crucial role in the healthy growth and development of offspring and has long-lasting effects. Recent studies have shown that it starts regulating fetal health and development during pregnancy and continues to influence early microbial colonization through birth and breastfeeding. There is compelling evidence that it is involved in immune and brain development and affects the risk of related diseases. Modulating offspring development through maternal diet and probiotic intervention during pregnancy and breastfeeding could be a promising future therapy.

Summary: This study investigated the effect of antibiotics administered to pregnant dams on offspring gut microbiome composition and metabolic capabilities, and how these changes in the microbiota may influence their immune responses in both the periphery and the brain. The results show that the antibiotic cocktail significantly altered the diversity and taxonomy of the offspring's gut microbiota. Additionally, the predicted metabolic pathways were also significantly changed. In response to LPS immune challenge, the brains of the offspring showed decreased levels of innate inflammatory cytokines and chemokines. These findings suggest that maternal antibiotic use can have long-lasting effects on the gut microbiome and neuroimmune responses of offspring.

Summary: Uncovering the mechanisms of fetal programming during pregnancy is crucial for understanding long-term health outcomes in offspring. Maternal factors such as inflammation, stress, anxiety, and depression have been linked to abnormal neurodevelopment and can potentially disrupt the microbiome, which is important for normal brain development. This study examined the association between maternal stress, anxiety, depression, inflammatory cytokines, and the offspring microbiome in the first 13 months of life. The results showed that higher maternal anxiety and stress were associated with reduced microbial diversity and altered abundance of beneficial bacterial species in the offspring. This provides strong evidence for a potential mechanism by which maternal factors can impact offspring health through dysregulation of the microbiota.

Summary: Smoking during pregnancy is strongly associated with adverse outcomes, and the effects of nicotine intake apart from smoking are less explored. This study reveals that changes in the maternal gut microbiome mediate the effects of prenatal nicotine exposure, influencing gene expression and altering fetal exposure to short-chain fatty acids and leptin during in utero development.

Summary: Acetylcholine plays an important role in regulating immune responses and is associated with the development of various diseases. This study demonstrates that Acetylcholine derived from group 2 innate lymphoid cells (ILC2s) limits excessive pulmonary neutrophilic inflammation and enhances eosinophilia. However, depletion of Acetylcholine inhibits ILC2 activation and suppresses eosinophilic inflammation. Acetylcholine also regulates macrophage phenotype in allergic airway inflammation.

Summary: Butyrate, produced by gut microbiota through fermentation of dietary fiber, serves as a key energy source for colonocytes. It has important roles in gastrointestinal health, impacting both host and microbial functions. Maintaining optimal butyrate levels improves gastrointestinal health by supporting colonocyte function, decreasing inflammation, maintaining the gut barrier, and promoting a healthy microbiome. However, increasing butyrate levels in humans and reversing negative outcomes have yielded mixed results, despite its protective actions in intestinal diseases.

Summary: Functional redundancy is a crucial ecosystem property in which different species contribute to the ecosystem in similar ways through redundant functions. This study quantifies the proteome-level functional redundancy (FRp) in the human gut microbiome using metaproteomics. The research reveals high proteome-level functional redundancy and nestedness in the human gut proteomic content networks. The findings show that proteomic content networks' nested topology and small functional distances between taxa contribute to high FRp. FRp outperforms diversity indices in detecting significant microbiome responses to various environmental factors.
