Project description:Gut microbiome research is rapidly moving towards the functional characterization of the microbiota by means of shotgun meta-omics. Here, we selected a cohort of healthy subjects from an indigenous and monitored Sardinian population to analyze their gut microbiota using both shotgun metagenomics and shotgun metaproteomics. We found a considerable divergence between genetic potential and functional activity of the human healthy gut microbiota, in spite of a quite comparable taxonomic structure revealed by the two approaches. Investigation of inter-individual variability of taxonomic features revealed Bacteroides and Akkermansia as remarkably conserved and variable in abundance within the population, respectively. Firmicutes-driven butyrogenesis (mainly due to Faecalibacterium spp.) was shown to be the functional activity with the higher expression rate and the lower inter-individual variability in the study cohort, highlighting the key importance of the biosynthesis of this microbial by-product for the gut homeostasis. The taxon-specific contribution to functional activities and metabolic tasks was also examined, giving insights into the peculiar role of several gut microbiota members in carbohydrate metabolism (including polysaccharide degradation, glycan transport, glycolysis and short-chain fatty acid production). In conclusion, our results provide useful indications regarding the main functions actively exerted by the gut microbiota members of a healthy human cohort, and support metaproteomics as a valuable approach to investigate the functional role of the gut microbiota in health and disease.

Project description:Immune cells in visceral adipose tissue are critical for regulating metabolic homeostasis. In addition, gut microbiota is an important regulator of the immune system. We used single-cell RNA sequencing (scRNA-seq) to analyze the relationship between gut microbiota and immune cells in visceral adipose tissue.

Project description:Early-life antibiotic exposure perturbs the intestinal microbiota, alters innate intestinal immunity, and accelerates type 1 diabetes development in the NOD mouse model. Here we found that maternal cecal microbiota transfer (CMT) to NOD mice with early-life antibiotic perturbation partially rescued the induced T1D acceleration. The restoration effects on the intestinal microbiome were substantial and persistent, remediating the antibiotic-depleted diversity, relative abundance of particular taxa, and metabolic pathways. CMT also protected against perturbed cecal and serum metabolites and normalized innate and adaptive immune effectors. CMT restored patterns of ileal microRNA and histone regulation of gene expression and exon-splicing. Based on the analyses of experimental data, we propose an innate intestinal immune network involving CD44, TLR2, and Reg3g, as well as their multiple microRNA and epigenetic regulators that sense intestinal signaling by the gut microbiota. This regulation affects downstream immunological tone, leading to protection against the tissue-specific T1D injury.

Project description:Although modern clinical practices such as cesarean sections and perinatal antibiotics have improved infant survival, treatment with broad-spectrum antibiotics alters intestinal microbiota and causes dysbiosis. Infants exposed to perinatal antibiotics have an increased likelihood of life-threatening infections, including pneumonia. Here, we investigated how the gut microbiota sculpt pulmonary immune responses, promoting recovery and resolution of infection in newborn rhesus macaques. Early-life antibiotic exposure interrupted the maturation of intestinal commensal bacteria and disrupted the developmental trajectory of the pulmonary immune system, as assessed by single-cell proteomic and transcriptomic analyses. Early-life antibiotic exposure rendered newborn macaques more susceptible to bacterial pneumonia, concurrent with increases in neutrophil senescence and hyperinflammation, broad inflammatory cytokine signaling, and macrophage dysfunction. This pathogenic reprogramming of pulmonary immunity was further reflected by a hyperinflammatory signature in all pulmonary immune cell subsets coupled with a global loss of tissue-protective, homeostatic pathways in the lungs of dysbiotic newborns. Fecal microbiota transfer was associated with partial correction of the broad immune maladaptations and protection against severe pneumonia. These data demonstrate the importance of intestinal microbiota in programming pulmonary immunity and support the idea that gut microbiota promote the balance between pathways driving tissue repair and inflammatory responses associated with clinical recovery from infection in infants. Our results highlight a potential role for microbial transfer for immune support in these at-risk infants.

Project description:Gut microbiota and the circadian clock are both key regulators of the metabolic processes. Although recent evidence points to the impact of the circadian clock on microbiota, gut microbiota effect on diurnal host gene expression remains elusive. A transcriptome analysis of germ-free mice reveals subtle changes in circadian clock gene expression. However, a lack of microbiome leads to liver feminization and alters the expression of male-specific genes involved in lipid metabolism and xenobiotic detoxification associated with sustained activation of the Growth Hormone pathway. These results emphasize the mutual interaction of gut microbiota and its host even on unexpected functions.
