Impact of chorioamnionitis exposure on neonatal monocyte H3K4me3 patterning

Project description:We sought to determine the impact of chorioamnionitis exposure on the neonatal monocyte H3K4me3 histone modification landscape over the course of fetal and neonatal immune system development using ChIP-seq. H3K4me3 ChIP-seq was performed on umbilical cord blood purified CD14+ monocytes from healthy and chorioamnionitis-exposed extremely preterm neonates (under 30 weeks gestation), late preterm neonates (30-36 weeks gestation), and term neonates (37+ weeks gestation).

Human Fetal and Adult Peripheral Naïve CD4+ T cells and CD4+CD25+ Treg cells

Project description:We compared differences in fetal and adult T cells by performing whole genome profiling on sort-purified T cells (naïve CD4+ and Treg cells) from human fetal specimens (18-22 gestational weeks) and adult specimens (age 25-40 years old). Fetal and Adult Naïve CD4+ T cells phenotype: CD3+CD4+CD45RA+CCR7+CD27+, Fetal and Adult CD4+CD25+ Treg phenotype: CD3+CD4+CD25bright Four different groups were analyzed: Fetal Naïve CD4+ T cells, Adult Naïve CD4+ T cells, Fetal Treg cells, Adult Treg cells. For each group three independent donors were analyzed.

The histone modification landscape of neonatal CD4+ T cells contributes to decreased T cell receptor signaling

Project description:Chromatin immunoprecipitation with massively parallel DNA sequencing (ChIP-seq) was performed to establish the H3K4me3 landscape in neonatal and adult naive CD4+ T cells. As development progressed from neonate to adult, naive CD4+ T cells gained the activating mark H3K4me3 at immunologically important promoter sites. Adult naive CD4+ T cells had enrichment of H3K4me3 at genes important in T cell receptor signaling, which was associated with improved markers of activation and cytokine expression in adult naive CD4+ T cells after engagement of the T cell receptor.

Neonatal naïve CD8+ T cells have effector-like gene expression that prevents memory cell formation [RNA-seq]

Project description:Neonates are intrinsically defective at creating memory CD8+ T cells in response to infection with intracellular pathogens. Here we investigated differential of small RNAs, transcription factors, and chemokine receptors regulation in neonates as compared to adults before and during infection. We found that prior to infection, naïve cells have a different expression profile for many microRNAs, and gene targets of these microRNAs show widespread expression differences. These targets and other changes in gene expression in naïve cells result in neonatal cells that get activated more easily, express chemokine receptors that home to sites of infection, and are less protected from apoptosis during contraction. As a result, changes in neonatal naïve cells drive effector cell terminal differentiation at the expense of creating long-lived memory cells. total RNAs were sequenced from adult and neonatal CD8+ T cells before and during infection
