Variation in primary CD4+ T cell response to activation across time and people

ABSTRACT: This SuperSeries is composed of the SubSeries listed below. Variation in individuals' adaptive immune response is believed to influence susceptibility to complex diseases in humans. The genetic basis of such variation is poorly understood. We analyzed the response of human CD4+ T cells from a cohort of 348 healthy humans, representing three major ancestries, to in vitro stimulation, alone or in Th17 conditions, or with IFNb stimulation.

Expression data measured by custom Nanostring gene set of CD4+ T cells from healthy individuals stimulated with anti-CD3/CD28 with or without IFNb or Th17 polarizing cytokines

Project description:Variation in individuals' adaptive immune response is believed to influence susceptibility to complex diseases in humans. The genetic basis of such variation is poorly understood. We measured gene expression from resting and activated CD4+ T cells derived from the peripheral blood of 348 healthy individuals. We activated the primary T cells with anti-CD3/CD28 beads. We collected peripheral blood from each human donor. We isolated peripheral blood mononuclear cells by Ficoll, and negatively selected for CD4+ T cells using RosettaSep. We isolated peripheral blood mononuclear cells by Ficoll, and negatively selected for CD4+ T cells using RosettaSep. We then either left cells unstimulated or stimulated them with beads conjugated with anti-CD3 and anti-CD28 either without additional cytokines, or with IFNb, or with Th17 cocktail. Cells were harvest at 0hr, 4hr (anti-CD3/CD28 +/- IFNb) or 48hr (anti-CD3/CD28 +/- Th17), lysed and RNA isolated to be profiled on Nanostring.

Expression data measured by microarray of CD4+ T cells from healthy individuals stimulated with anti-CD3/CD28

Project description:This SubSeries in the ImmVar project investigates the response of selected genes in T cells from healthy human individuals to ascertain the impact of genetic or non-genetic variation on T cell activation parameters. We measured gene expression from resting and activated CD4+ T cells derived from the peripheral blood of healthy individuals. We activated the primary T cells with anti-CD3/CD28 beads alone or with IFNb or Th17 polarizing cytokines.

IFNb-1a in-vivo treatment induces the expression and signaling of IFNAR1 and inhibits Th17 responses in PBMCs derived from CIS patients

Project description:IFNb has been used as a first line therapy for relapsing remitting multiple sclerosis (RRMS). Since only a few studies have addressed the role of endogenous IFNb in the pathogenesis of the disease, our objective was to characterize its role in the transcriptional regulation of pathogenic Th17 cytokines in patients with RRMS. In-vitro studies have demonstrated that IFNb inhibited IL-17A, IL-17F, IL-21, IL-22 and IFN-b secretion in CD4+ lymphocytes through the induction of suppressor of cytokine secretion (SOCS)1 and 3. We found that patients with RRMS have increased serum and cerebrospinal fluid (CSF) Th17 (IL-17A and IL-17F) cytokine levels in comparison to the control subjects, suggesting that deficient endogenous IFNbeta secretion and/or signaling may contribute to the dysregulation of those pathogenic cytokines in CD4+ cells. We identified that the endogenous IFNb from serum of RRMS patients induced a significantly lower IFN-inducible gene expression in comparison to healthy controls (HCs). In addition, in-vitro studies have revealed a deficient endogenous and exogenous IFNb signaling in CD4+ cells derived from MS patients. Interestingly, upon inhibition of the endogenous IFNb signaling by silencing interferon regulatory factor (IRF)7 gene expression, the resting CD4+ T cells secreted significantly higher level of IL-17A, IL-17F, IL-21, IL-22 and IL-9, suggesting that endogenous IFNb suppresses the secretion of these pathogenic cytokines. In-vivo recombinant IFNb-1a treatment induced IFNAR1 and its downstream signaling molecules’ gene expression, suggesting that treatment may reconstitute a deficient endogenous IFNbeta regulation of the CD4+ T-cells’ pathogenic cytokine production in MS patients.

Expression data measured by Nanostring of monocyte-derived dendritic cells from healthy individuals stimulated with LPS, influenza, or IFN-beta, or left unstimulated

Project description:Variation in individuals' responses to environmental factors is believed to influence susceptibility to complex diseases in humans. The genetic basis of such variation is poorly understood. We measured gene expression from resting and stimulated dendritic cells (DCs) derived from the peripheral blood of healthy individuals. We stimulated the primary DCs with E. coli lipopolysaccharide (LPS), influenza virus or the cytokine IFNβ, and associated genetic variation between individuals with the observed variation in gene expression and gene induction.

Whole-genome comparison of meticillin-resistant Staphylococcus aureus CC22 SCCmecIV from people and their in-contact pets.

Project description:BACKGROUND: Meticillin-resistant Staphylococcus aureus (MRSA) infections remain important medical and veterinary challenges. The MRSA isolated from dogs and cats typically belong to dominant hospital-associated clones, in the UK mostly EMRSA-15 (CC22 SCCmecIV), suggesting original human-to-animal transmission. Nevertheless, little is known about host-specific genetic variation within the same S. aureus lineage. HYPOTHESIS/OBJECTIVES: To identify host-specific variation amongst MRSA CC22 SCCmecIV by comparing isolates from pets with those from in-contact humans using whole-genome microarray. METHODS: Six pairs of MRSA CC22 SCCmecIV from human carriers (owners and veterinary staff) and their respective infected in-contact pets were compared using a 62-strain whole-genome S. aureus microarray (SAM-62). The presence of putative host-specific genes was subsequently determined in a larger number of human (n = 47) and pet isolates (n = 93) by PCR screening. RESULTS: Variation in mobile genetic elements (MGEs) occurred frequently and appeared largE: The variation found amongst MGEs highlights that genetic adaptation in MRSA continues. However, host-specific MGEs were not detected, which supports the hypothesis that pets may not be natural hosts of MRSA CC22 and emphasizes that rigorous hygiene measures are critical to prevent contamination and infection of dogs and cats. The host specificity of individual heavy-metal resistance genes warrants further investigation into different selection pressures in humans and animals.
