16S rRNA sequences from a longitudinal study on infants

Project description:The objective of the present study was to identify the nutrient utilization and the SCFA production potential of gut microbes during the first year of life. The 16S sequencing data represents 100 mother-child pairs, longitudinally for the infants (0, 3mo, 6mo and 12mo) and mothers 18 weeks pregnancy. We wanted to identify the SCFA composition in pregnant woman and their infants through the first year of life, and their correlation to gut bacteria and other influencal factors. Metaproteomics on selected infants were analyzed to look for nutrient sources used by potential SCFA producers.

Molecular Networks in Atopic Mothers Impact the Atopy Risk of Infants

Project description:The prevalence of atopic diseases has increased with atopic dermatitis (AD) as the earliest manifestation. We assessed if molecular risk factors in atopic mothers influence their offsprings’ susceptibility to an atopic disease. Pairs of pregnant women and their infants with or without parental atopy were followed over the first 2 years of life. Global DNA methylation and differentially methylated regions (DMR) were determined in atopic and non-atopic mothers. During the first 2 years of life, AD was more prevalent in children of atopic compared to non-atopic mothers with an increase in food sensitization in children with AD. 165 DMRs distinguished atopic from non-atopic mothers. Maternal atopy combined with DMRs increased the offsprings’ predicted risk to develop AD from an odds ratio of 2.56 to 4.26.

Methylation arrays (MethylationEPIC) of cord and peripheral whole blood from children born to mothers with obesity or gestational diabetes, with longitudinal follow-up during their first year of life

Project description:Epidemiological studies have associated maternal metabolic conditions such as obesity and gestational diabetes with poor health outcomes in the offspring. Epigenetic mechanisms may help explain the intrauterine influence that mothers have on their offspring during pregnancy. Here, using Illumina's MethylationEPIC array technology, we have longitudinally profiled the blood methylomes of children born to mothers with obesity and obesity with gestational diabetes, and healthy controls, during the first year of life (measurements at 0, cord blood; 6 and 12 months, peripheral blood).

Fetal-derived activated CD83+ γδ T cells expand in preterm infants with sepsis.

Project description:Here, we investigated γδ T cells in a longitudinal cohort of preterm neonates during the first year of life. Our data reveal dynamic postnatal maturation patterns of γδ T cell subsets, which are largely age-dependent. We report on the expansion of fetal-derived γδ T cells in preterm neonates with sepsis. Single cell transcriptome analyses identified HLA-DRhigh and CD83+ γδ T cells in neonatal sepsis.

Genome-wide methylation changes in maternal microchimeric cells from Mmc+ and Mmclow offspring mice

Project description:During mammalian pregnancy, immune cells are vertically transferred from mother to fetus. The functional role of these maternal microchimeric cells (MMc) is largely unknown. We show that MMc induce a preferential differentiation of hematopoietic stem and progenitor cells towards myelopoiesis in bone marrow of fetal mice, and improves resilience against cytomegalovirus infection in neonates. In humans, low MMc counts in cord blood are associated with an increased number of infections in the first year of life primarily in male newborns. Taken together, MMc boost neonatal immunity in mice and humans to mitigate the risk for early life infections.

Maternal Nurtritional Programming in the Ovine Mammary Gland

Project description:Developmental programming is the concept that environmental factors, particularly during foetal life, can alter development, metabolism and physiology of an organism and this can have consequences later in life. There is growing interest in developmental programming in livestock species, particularly effects of maternal pregnancy nutrition, which is easy to manipulate. Recent research, using a sheep model, has shown that milk production in ewe offspring may be susceptible to maternal nutritional programming, such that over nutrition (ad libitum) of the pregnant dam, compared with maintenance nutrition, may impair their first lactation performance and result in the weaning of lighter lambs. RNA-seq was performed to identify gene expression differences as a result of maternal nutrition in ewe offspring during their first parity. Samples were collected in late pregnancy and during lactation, allowing us to examine gene expression changes during maturation of the ovine mammary gland. Three biological replicates were sequenced for each of the treatment conditions (maternal nutrition: sub-maintenance, maintenance, and ad libitum) and time points (late pregnancy and lactation). Each biological replicate consisted of RNA from multiple individuals (late pregnancy n=3, lactation n=2).

Distinct peripheral blood mononuclear cells transcriptional modules in the response to human respiratory syncytial virus or human rhinovirus in hospitalized infants with bronchiolitis

Project description:Human respiratory syncytial virus (HRSV) is the main cause of bronchiolitis during the first year of life, but other viruses such as rhinovirus also occur and are clinically indistinguishable. In hospitalized infants with bronchiolitis, the analysis of the peripheral blood mononuclear cells (PBMC) gene expression might be useful for identification the etiologies caused by HRSV and human rhinovirus (HRV) and to the development of future tests, as well as to elucidate the pathogenic mechanisms triggered by different viral agents and new therapeutic possibilities. In this study, we conducted a comparative global gene expression analysis of infants with acute viral bronchiolitis infected by HRSV (HRSV group) or HRV (HRV group).
