Healthy volunteers gene expression study of CD4 and NK lymphocytes

ABSTRACT: Sixteen volunteers, that were age, gender and BMI matched, were included in the study. Blood samples were taken one per each volunteer on three different days to also assess variability of gene expression markers in one individual. In all datasets variability between volunteers was higher than variability of measurables in samples collected from the same volunteer on different days. We have identified genes in individuals that are highly stable during one month period and are thus suitable as markers of individual disease/therapy progress. A list of genes with low overall variability is also available. Interestingly, data show that important components of immune response are down-regulated with BMI in T helper and NK cells. This paper also gives the first insight into the gene expression profile of T helper and NK cells in healthy population.

CD4 and NK lymphocytes were isolated with positive selection using magnetic nanoparticle based kits from StemCell Inc. (Canada) and frozen to -80°C until total RNA extraction.

Longitudinal profiling of the whole blood transcriptional response of human volunteers to repeated malaria challenge

Project description:We took a systems immunology approach to analyse the evolution of the human immune response to the first three infections of life in a re-challenge model of falciparum malaria. Ten volunteers were infected up to three times with Plasmodium falciparum in 4- to 8-month intervals. Remarkably, parasite densities and the dynamics of blood-stage infection were not altered over the course of three homologous infections. To track the development of immunity in real-time we used whole blood RNA-sequencing to analyse each volunteer’s transcriptional response throughout infection and convalescence (up to 9 time points per volunteer per infection).

Global gene expression of hiPS cell derived cardiomyocytes from healthy volunteers

Project description:To investigate the relationship between inter-individual difference of drug susceptibility and global gene expression, gene expression profiles of human iPS cell-derived cardiomyocytes (hiPSC-CMs) generated from healthy volunteers were compared with each other.

Gene expression analysis of peripheral blood mononuclear cells prior to and following vaccination of human volunteers with the novel TB vaccine candidate MVA85A

Project description:A greater understanding of the relationships between a vaccine, the immune response it induces, and protection from disease would greatly facilitate vaccine development. Modified Vaccinia virus Ankara expressing antigen 85A (MVA85A) is a novel tuberculosis (TB) vaccine designed to enhance responses induced by Bacille Calmette-Guerin (BCG). Antigen-specific interferon-γ (IFN-γ) production is greatly enhanced by MVA85A and peaks one week post-vaccination, however, the variability in response between healthy individuals is extensive. In this study we have sought to characterize the early changes in gene expression following vaccination with MVA85A and understand how these are related to long-term immunogenicity. 24 volunteers were vaccinated with 10^8 pfu MVA85A. 12 volunteers were vaccinated intramuscularly and 12 intradermally. Volunteers were healthy and did not have HIV, HCV, HBV or latent or active tuberculosis. Blood for this study was taken on the day of vaccination, immediately prior to the vaccine being given (day 0), and 2 and 7 days post-vaccination.

GNPS - BP-Microbiome_Skin samples 12 volunteers

Project description:LC-MS/MS data were collected from skin swabs of 11 volunteers over a period of 9 weeks and for one volunteer during one week. Volunteers were asked to follow instructions required over our 9 weeks study: - We provided the same head to toe shampoo to all volunteers, that was used during shower for the first 6 weeks. - Week 1 to week 3: no other beauty products was used. - Week 4 to week 6: we provided 5 selected commercial beauty products that all volunteers applied daily on specific body part (deodorant for armpits, soothing foot powder for feet, sunscreen for face and moisturizer for arm back). - Week 7 to week 9: back to normal routine. - Samples were collected every week, before during and after application of beauty products.

Gene expression of primary human T Follicular Helper (TFH) cells and naive CD4-positive helper T cells from tonsils of healthy volunteers

Project description:In this experiment we generated Affymetrix gene expression data for T Follicular Helper (TFH) cells from tonsils of healthy volunteers (4 biological replicates) and naive CD4-positive helper T cells (2 biological replicates). TFH cells provide a model relevant to SLE as TFH operate upstream of the activation of pathogenic autoantibody-producing B cells during the disease. This experiment accompanies promoter capture-C and ATAC-seq experiments on the same cell types.

Transcription profiling of Baseline gene expression in circulating peripheral blood mononuclear cells isolated from 18 apparently healthy volunteers (10 females and 8 males)

Project description:Baseline gene expression in circulating peripheral blood mononuclear cells isolated from 18 apparently healthy volunteers (10 females and 8 males). The volunteers fasted overnight for 10 hours prior to collection of blood samples (but they were allowed water). 5 blood samples were collected from each volunteer at consecutive 8-day intervals. Volunteers were included in this study provided they met the following selection criteria, that they should be ?Aged between 20 and 45 years of age; ?A non-smoker (or an ex-smoker); ?Not pregnant or been pregnant in the last 12 months ?Not diagnosed with any long-term medical condition; ?Or have not (in the previous 4 months) donated blood, received any inoculations and are not taking regular prescribed medicine (including HRT and oral contraception) Prior to inclusion in this study volunteers were screened for general health and had a blood sample taken for routine screening of Hb content etc. Only those volunteers who were in good general health were allowed to participate in the study. The age of all volunteers has been reported here as being 20-45 years in order to preserve the anonymity of the data, and so that the individuals involved may not be able to track down their own specific data. Please contact us if the details of volunteers' ages are required.

Human leukocytes from 6 volunteers before and 2h after pectin capsules consumption (I)

Project description:Methanol (MeOH) is considered to be a poison in humans because of the alcohol dehydrogenase (ADH)-mediated conversion of MeOH into toxic formaldehyde (FA). Our recent genome-wide analysis of the mouse brain demonstrated that an increase in endogenous MeOH after ADH inhibition led to a significant increase in the plasma MeOH concentration and the modification of mRNA synthesis. These findings suggest endogenous MeOH involvement in homeostasis regulation by controlling mRNA levels. Here, we demonstrate directly that study volunteers displayed increasing concentrations of MeOH and FA in their blood plasma when consuming citrus pectin, ethanol and red wine. A microarray analysis of white blood cells (WBC) in volunteers after pectin intake showed various responses for 30 differentially regulated mRNAs. Most of the mRNAs were somehow involved in the pathogenesis of Alzheimer's disease (AD). There was also a decreased synthesis of hemoglobin mRNA, HBA and HBB, the presence of which in WBC RNA was not a result of red blood cells contamination because erythrocyte-specific marker genes did not show significant change. A qRT-PCR analysis of volunteer WBC after pectin and red wine intake confirmed the complicated dependence between plasma MeOH content and the mRNA accumulation of previously identified genes, namely GAPDH and SNX27, and MME, SORL1, DDIT4, HBA and HBB genes revealed in this study. We hypothesized that human plasma MeOH, which is replenished from endogenous and exogenous sources (diet), has an impact on the WBC mRNA levels of genes involved in AD pathogenesis and signaling. The subjects fasted for 12 hours prior to beginning each experiment and evaluation session. Each volunteer swallowed capsules with PME containing citrus pectin (6 g) (Nittary Pharmaceuticals, VitaLine, Inc., USA). After 120 min blood samples were obtained. Total RNA was isolated from WBCs with TriReagent (MRC, USA) according to the manufacturer’s protocol.
