Transcriptional responses in whole blood of healthy adult volunteers experimentally challenged with S. Paratyphi

Project description:This studies describes the transcriptional response in whole blood derived from healthy adult volunteers experimentally infected with S. Paratyphi A. Samples were collected at pre-challenge baseline (Group: CTRL), at day 7 after challenge in those participants who stayed well over 14 days following challenge (Group: suspected Enteric Fever - sEF). Participants who developed signs of enteric fever were sampled at the time of inititiation of antibiotics (Group: EF).In this group diagnosis was confirmed by blood culture positive for S. Paratyphi (SPT). Antibiotic therapy commenced at time of diagnosis or at day 14 after challenge in those who did not develop symptoms. The clinical results of this study have been published in: Dobinson et al. Evaluation of the Clinical and Microbiological Response to Salmonella Paratyphi A Infection in the First Paratyphoid Human Challenge Model. Clin Infect Dis. 2017 Apr 15;64(8):1066-1073.

Transcriptional responses in whole blood of healthy adult volunteers experimentally challenged with S. Typhi

Project description:In this study, whole blood samples were used to determine the gene expression of healthy adult volunteers experimentally challenged with S. Typhi Quailes strain. Samples were collected at baseline (pre-challenge; Group: CTRL) and 7 days after challenge (Group: sEF) in individuals who did not reach diagnostic criteria. In those reaching the diagnostic endpoint (typhoid fever; Group: EF) the sample on the day of diagnosis when antibiotic treatment commenced was taken. These samples were derived from the placebo arm of a recent a Single Centre, Randomised, Doubleblind, Placebo Controlled Study to Evaluate M01ZH09 in a Healthy Adult Challenge Model, Using Ty21a Vaccine as a Positive Control.

Time Course of Young Adults Vaccinated with Meningococcal MCV4 and MPSV4 Vaccines

Project description:We performed systems analyses of immune responses to the meningococcal polysaccharide (MPSV4) and conjugate (MCV4) vaccines in healthy adults. The goal was to identify innate gene signatures that correlate to antibody responses induced by these vaccines. Healthy adult volunteers (18-45 years of age) were randomized to be vaccinated subcutaneously with MPSV4 (MenomuneÂ®, n=13) or intramuscularly with MCV4 (MenactraTM, n=17) (Sanofi Pasteur, Swiftwater, PA). Whole blood samples were collected using CPT tubes at days 0, 3 and 7 post-vaccination. Peripheral blood mononuclear cells (PBMC) were isolated from fresh blood and used for DNA microarray experiments.

Microbiome and Inflammatory Interactions in Obese and Severe Asthmatic Adults

Project description:In order to better understand the systemic immunological responses in a clinical cohort of obese and non-obese asthmatics and healthy subjects, we sought to analyze gene expression from whole blood. We collected whole blood samples from 156 donors and performed gene expression analysis of these samples and identified differentially expressed genes (DEGs) in each obese and/or asthma group relative to healthy volunteers.

TCR repertoire of effector CCR7-CD38+ cells accumulating during experimental infection with Typhoidal Salmonella

Project description:In order to characterize pathogen specific T cell responses against Salmonella volunteers challenged with Salmonella enterica serovar Typhi (S. Typhi) or Salmonella Paratyphi A (S. Paratyphi). we used mass cytometry, to identify effector CD4+ T cells circulating during infection. We identified a population of CCR7-CD38+ cells accumulating during infection, and via unbiased single cell cloning and expansion we demonstrated that these CCR7-CD38+ cells are enriched in Salmonella specific T cells. In this experiment we performed TCR repertoire analysis of CCR7-CD38+ and CCR7-CD38- cells to determine the clonality of CCR7-CD38+ cells, the overlap between the repertoire of CCR7-CD38+ cells and of non-activated effector CCR7-CD38- cells, and to identify within CCR7-CD38+ and CCR7-CD38- cells the presence of the CDR3b TCR sequence of the pathogen specific T cell clones isolated from CCR7-CD38+ cells

Transcriptional responses in whole blood of febrile individuals in Nepal

Project description:In this study, whole blood samples were used to determine the gene expression of febrile culture confirmed enteric fever cases (ST = S. Typhi; SPT = S. Paratyphi), febrile culture negative individuals presenting to hospital in Kathamandu (sEF = suspected enteric fever), and healthy community controls (CTRL).
