Transcription profiling by array of mouse dendritic cells stimulated with live influenza virus, influenza whole inactivated virus vaccine or subunit vaccine.

ABSTRACT: Vaccine development involves time-consuming and expensive evaluation of candidate vaccines in animal models. As mediators of both innate and adaptive immune responses dendritic cells (DCs) are considered to be highly important for vaccine performance. Here we evaluated in how far the response of DCs to a vaccine in vitro is in line with the immune response the vaccine evokes in vivo. To this end, we investigated the response of murine bone marrow-derived DCs to whole inactivated virus (WIV) and subunit (SU) influenza vaccine preparations. These vaccine preparations were chosen because they differ in the immune response they evoke in mice with WIV being superior to SU vaccine through induction of higher virus-neutralizing antibody titers and a more favorable Th1-skewed response phenotype. To evaluate if in vivo immunogenicity is reflected by DC reactions in vitro we studied the gene expression signature of murine bone-marrow-derived conventional DCs (cDCs) upon stimulation with WIV or SU influenza vaccine or, for reasons of comparison, with live influenza virus. Dendritic cells stimulated with PBS served as a control. Gene expression analysis was performed on samples 4, 12 and 24 hours after the start of stimulation.

single cell RNA sequencing of migratory dendritic cells after intranasal adjuvant/tolerogen administration

Project description:We compared migratory DCs in draining mediastinal lymph node after intranasal administration of different vaccine adjuvants based on CTA1 subunit of cholera toxin. The goal was to determine different characteristics of dendritic cells subsets after pro-inflammatory vs tolerogenic adjuvant. We had 3 groups: CTA1-DD (pro- inflammatory), CTA1(R7K)-DD (tolerogenic) and PBS to define DC which migrate to LN. All vaccine constructs included 3Ea peptide to allow for sorting of DC which took up the vaccine.

Transcription profiling of liver from flounder after injection with a vaccine containing killed Aeromonas salmonicida, the bacterium responsible for furunculosis

Project description:To study the effects of bacterial infection upon gene expression changes in flounder liver fish were artificially "infected" by injection with a commercial water-based vaccine containing killed Aeromonas salmonicida, the bacterium responsible for furunculosis, which, as its name describes, presents as external lesions (furuncles, "lumps"). This disease occurs in flounder as well as in salmonids. Flounders were treated by intraperitoneal injection with 1ml/kg Furunculosis vaccine (Schering-Plough, Aquavac Furovac 5, batch number FNM/C/007). 30 control fish were injected with 1% saline. Animals were then maintained unfed in static aerated sea water tanks in a constant temperature containment aquarium. Water was renewed every 2 days. After 1, 2, 4, 8, and 16 days, 6 vaccine treated and 6 saline control fish were removed, killed by a blow to the head and samples of liver tissue were immediately homogenized in TriReagent prior to gene expression profiling. Microarray experiments consisted an individual array for each of 4 or 5 fish from each timepoint and each treatment compared with an artificial reference sample.

Immunosignatures can predict vaccine efficacy

Project description:Mice were immunized with either formalin fixed Influenza A/PR/8/34 (Killed PR8), the 2006-2007 seasonal influenza vaccine, the 2007-2008 seasonal influenza vaccine, a sublethal infection (live PR8) or mock immunized (PBS). Array data was used to distinguish the immunogens from each other and predict which of the three inactivated vaccines would be protective against A/PR/8/34 challenge. two replicates of each peptide was printed on 1 CIM_10kv3 peptide microarray. One microarray were tested for each sample. Image was qualified using in-house metrics for quality assurance.

Segmentation and intensity estimation for microarray images with saturated pixels

Project description:Images and gpr files were examined using a novel saturation reduction method to determine whether accuracy could be improved by extending dynamic range of saturated pixels Three immunosignatures from human Valley Fever (Coccidiodes) patients and three immunosignatures from human influenza vaccine recipients were examined to test an algorithm that extends the apparent dynamic range of a fluorescence image. These images had several saturated spots at 70PMT and 100% laser power. The program examined the differences between Valley Fever and influenza in terms of standard image processing vs. segmentation and intensity estimation.

Molecular Characterization of In Vivo Adjuvant Activity in Ferrets Vaccinated against Influenza Virus

Project description:The 2009 H1N1 influenza pandemic has prompted a significant need for the development of efficient, single-dose, adjuvanted vaccines. Here we investigated the adjuvant potential of CpG oligodeoxynucleotide (ODN) when used with a human seasonal influenza virus vaccine in ferrets. We found that the CpG ODNadjuvanted vaccine effectively increased antibody production and activated type I interferon (IFN) responses compared to vaccine alone. Based on these findings, pegylated IFN- 2b (PEG-IFN) was also evaluated as an adjuvant in comparison to CpG ODN and complete FreundM-bM-^@M-^Ys adjuvant (CFA). Our results showed that all three vaccines with adjuvant added prevented seasonal human A/Brisbane/59/2007 (H1N1) virus replication more effectively than did vaccine alone. Gene expression profiles indicated that, as well as upregulating IFN-stimulated genes (ISGs), CpG ODN enhanced B-cell activation and increased Toll-like receptor 4 (TLR4) and IFN regulatory factor 4 (IRF4) expression, whereas PEG-IFN augmented adaptive immunity by inducing major histocompatibility complex (MHC) transcription and Ras signaling. In contrast, the use of CFA as an adjuvant induced limited ISG expression but increased the transcription of MHC, cell adhesion molecules, and B-cell activation markers. Taken together, our results better characterize the specific molecular pathways leading to adjuvant activity in different adjuvant-mediated influenza virus vaccinations. In this experiment, 3 ferrets in each group immunizied with different adjuvanted human seasonal vaccines of CFA plus vaccine, CpG plus vaccine, pegylated IFN-alpha plus vaccine and vaccine alone (PBS plus vaccine) and 4 ferrets from control group (PBS only) were anesthetized at day 1 post vaccination. The whole blodd was collected for RNA extraction and purification on the scheduled date. The subsequent gene expression analysis was performed with Affymetrix GeneChip Canine Genome 2.0 Array.

Transcription profiling of human peripheral blood monocytes from volunteers in a malaria vaccine trial

Project description:Volunteers were assessed at study entry, the day of the third vaccination and 24, 72 hours, two weeks after vaccination, and 5 days after challenge. 13/39 vaccinees were protected and 26/39 were not protected. Eleven vaccinees exhibited delayed onset of parasitemia. All infectivity controls developed parasitemia. Prediction Analysis of Microarrays (PAM-R) identified genes corresponding with protection. Gene Set Enrichment Analysis (GSEA) identified sets of genes associated with protection after the third immunization, before challenge. After the third immunization, prior to challenge, differential expression of genes in the immunoproteasome pathway distinguished protected and non protected persons Experiment Overall Design: Samples were collected at study entry, the day of third vaccination, 24 and 72 hours post the third vaccination and two weeks post the third vaccination as well as 5 days post challenge. Both longitudinal and cross-sectional analysis were carried out to investigate expression profiles associated with vaccine effects and vaccine efficacy. This dataset contains 215 samples from HG-U133 A 2.0 platform and 39 samples from HG Plus2.0 platform.

A proteomics-based method for identifying antigens within immune complexes

Project description:A novel approach to recover and identify immune complexes (ICs) was developed using size exclusion chromatography (SEC) and affinity chromatography on immunoglobulin binding columns (HiTrap Protein G). The purification process was monitored by 1D SDS-PAGE, protein staining, Western blotting and, finally, liquid chromatography tandem mass spectrometry (LC MS/MS) was used to identify the recovered antigens. This approach was applied to serum with artificially created immune complexes (ICs) comprising vaccine antigen (influenza) and antibody, which led to recovery and identification of influenza peptides within the recovered ICs. This approach was compared with the established method for IC detection and recovery, polyethylene glycol (PEG) precipitation, followed by LC MS/MS. Both approaches successfully enabled capture, recovery and characterization of immunoglobulins and influenza antigen(s) in complex with the immunoglobulins. However, PEG precipitation has the advantage of simplicity and is more suited for large scale studies.

Transcriptome analysis reveals an activation of MHC-I and MHC-II pathways in chicken trachea immunized with infectious laryngotracheitis virus vaccine

Project description:Infectious laryngotracheitis (ILT) is an acute, contagious, upper respiratory disease, which is caused by gallid herpesvirus 1 (GaHV-1). Due to the mortality rates up to 70% depending on the virulence of the virus, it is of economic importance of the disease to explore the etiology of the ILT in the poultry industry. In this study, 15-day-old SPF white leghorn chickens were used to transcriptome analysis in chicken trachea immunized with infectious laryngotracheitis virus vaccine. In conclusion, chicken embryo origin (CEO) vaccine activation of the MHC-I and MHC-II pathways provides insight into the molecular mechanism of immune response in chickens, and holds potential for evaluation and design of new ILT vaccines in a manner adapted to the host immune response to the virus. Ten vaccine inoculated birds were randomly divided in two groups. Each group represents one replication of five pooled tissues, for inoculated birds. Control group consists of five birds that received sterile vaccine diluent.
