Project description:We performed transcriptomic analysis of a Ebola virus (EBOV) infected hepatocyte cells. We utilized primary human hepatocytes (PHHs), iPSC-derived hepatocytes (iHeps), and immortalized hepatocarcinoma cell line Huh7 cells. Cells were infected with a multiplicity of infection of 10 and harvested after 1 day. Corresponding Mock infected samples were also included in this study.

Project description:The purpose of this experiment was to obtain samples for transcriptome analysis using wild-type viruses: Zaire Ebola (ZEBOV '76) and Reston Ebola (REBOV '08). Overview of Experiment: Cells: Immortalized Human Hepatocytes (IHH); seed 60,000 cells per well in a 24-well plate. Infected with a multiplicity of infection (MOI) of 0.5. After infection, 3x wash with PBS and replace with 5% FCS DMEM without NaPyr or NEAA. Time matched mocks done in triplicate from same cell stock as rest of samples. Time Points = 0, 8, 24, 48, and 72 hrs post infection in triplicate. (For miRNA: 8, 24, 48, 72 hours.)

Project description:We inoculated ARPE-19 human retinal pigment epithelial cells with EBOV, and followed course of infection by immunocytochemistry and measurement of titer in culture supernatant. To interrogate transcriptional responses of infected cells, we combined RNA sequencing with in silico pathway, gene ontology, transcription factor binding site and network analyses. Human retinal pigment epithelial cells were permissive to infection with EBOV, and supported viral replication and release of virus in high titer. Unexpectedly, 28% of 560 up-regulated transcripts in EBOV-infected cells were type I IFN responsive, indicating a robust type I IFN response.

We took sequential samples of peripheral blood mononuclear cells (PBMC) from 15 cynomolgus macaques infected intramuscularly with 1000 plaque forming units (PFUs) of EBOV, Zaire strain. Peripheral blood samples (2.5mL) were collected on days 1, 4, or 6 prior to infection, in order to define a robust baseline, and then on successive days after infection, until death (immediately prior to euthanasia). Animals were euthanized at days 1, 2, 3, 4, 5, and 6 postinfection. PBMC's were collected at days post-infection as noted, preserved in Trizol, Trizol-extracted total RNA, 1 round amplified (Ambion MessageAmp I), directly labeled by Cy5 incorporation during reverse transcription of amplified RNA. Each blood sample was hybridized versus a common reference. The same reference is used for all samples - Stratagene Universal Human Reference RNA, 1 round of amplification (Ambion MessageAmp I), directly labeled by Cy3 incorporation during reverse transcription of amplified reference RNA. Two to three biological replicates of pre-infection samples were taken for each animal, as well as two to nine biological replicates (from different animals) at each day post-infection. A total of 50 arrays, representing 15 animals is included in this dataset.

Project description:Ebola (EBOV) virus causes severe and often lethal hemorrhagic fever in humans and nonhuman primates (NHP), and has been classified as a Category A bioweapon agent. There are currently no approved preventive vaccines or postexposure treatments for EBOV hemorrhagic fever. The mechanisms of EBOV pathogenesis are only partially understood, but the dysregulation of normal host immune responses (including destruction of lymphocytes, increases in levels of circulating proinflammatory cytokines, and development of coagulation abnormalities) is thought to play a major role. Accumulating evidence suggests that much of the observed pathology is not the direct result of virus-induced structural damage but rather is due to the release of soluble immune mediators from EBOV-infected cells. It is therefore essential to understand how the candidate therapeutic may be interrupting the disease process and/or targeting the infectious agent. Identification of effective treatment strategies may greatly benefit based on identification of molecular features of the host response to infection and treatment. In order to identify these gene signatures related to correlates of protection, we used a DNA microarray-based approach to compare the host genome-wide responses of EBOV-infected NHP responding to candidate therapeutics. With this approach, we have identified genes that appear to correlate with survival, including chemokine ligand 8 (CCL8/MCP-2), and revealed a subset of distinctly differently expressed genes that may provide possible targets for future diagnostics or therapeutics. These analyses will assist us in understanding the pathogenic mechanisms of EBOV infection as well as identify improved therapeutic strategies. Transcriptional analysis of global gene expression changes in Zaire Ebola Virus (ZEBOV)-infected rhesus macaques that were treated with either recombinant nematode anticoagulant protein c2 (rNAPc2) or recombinant human activated protein C (rhAPC). Animals were infected with 1000pfu ZEBOV, then subsequently treated with rNAPc2 or rhAPC. Four animals were left untreated for controls. Blood samples were taken at specified days post-infection and PBMCs were isolated from the samples and inactivated in TRIzol reagent. Total RNA was isolated from the samples, then linearly amplified and hybridized to a whole genome long-oligonucleotide microarray in a two color comparative format with a commercially available human reference RNA from Stratagene as a consistent control in dataset comparisons.

Project description:Ebola virus can cause a severe and often fatal hemorrhagic fever in humans and other mammals, known as Ebola virus disease (EVD),the mechanism of how this pathogenesis comes about is not well understood, It is assumed that miRNA may have important roles in virus infection response. To better understand the function of miRNA in EBOV infection disease, we undertook a miRNA profiling analysis using the whole blood of EBOV infection patients.
