Next Generation Sequencing Facilitates Quantitative Analysis of Mock/MASCp36 infected mouse lung Transcriptomes

ABSTRACT: The ongoing SARS-CoV-2 pandemic has brought an urgent need for animal models to study the pathogenicity of the virus. Herein, we generated and characterized a novel mouse-adapted SARS-CoV-2 strain named MASCp36 that causes acute respiratory symptoms and mortality in standard laboratory mice. Particularly, this model exhibits age and gender related skewed distribution of mortality akin to severe COVID-19, and the 50% lethal dose (LD50) of MASCp36 was ~100 PFU in aged, male BALB/c mice. To characterize the transcriptional response to infection of MASCp36 in BALB/c mice (different age and gender), RNA-Seq analysis were performed using lung homogenates collected at 1 and 4 dpi.

SM003 - icSARS CoV, SARS MA15 wild type and SARS BatSRBD mutant virus infections of C57BL6 mice - A time course

Project description:The purpose of this experiment was to investigate the transcriptional differences between mice infected with icSARS CoV, SARS MA15 wild type or SARS BatSRBD viruses. Overview of Experiment: Groups of 20 week old C57BL6 mice were infected with icSARS CoV, Wild Type SARS MA15 or SARS BatSRBD mutant viruses. Infections were done at 10^4 PFU or 10^5 PFU or time-matched mock infected. Time points were 1, 2, 4 and 7 d.p.i. There were 3-5 animals/dose/time point. Lung samples were collected for virus load, transcriptional and proteomics analysis. Weight loss and animal survival were also monitored.

Gene Expression Analysis of Host Immune Responses in CD11b positive cells isolated from lungs of the UV inactivated SARS-CoV-immunized mice following Lethal SARS-CoV Infection

Project description:To better understand the biological pathways by which UV inactivated SARS-CoV-induced pulmonary eosinophilia occurs, we examined global transcriptional changes in macrophages from the lungs of mouse. Female BALB/c mice were used at 21 weeks of age. Mice were subcutaneously immunized with UV inactivated SARS-CoV (UV-V) or UV-V and Toll like receptor (TLR) ligands at 6 and 1 weeks prior to mouse-adapted SARS-CoV (n=6 per group). Mice were intranasally challenged with 1E+6 TCID50 in 30M-NM-<L. MEM was challenged in six mice as control infection. Mice were sacrificed and collected lungs at 1 days after challenge, then CD11b positive cells were isolated from the lungs of these mice. These cells were used for the analysis of microarray.

Gene Expression Analysis of Host Innate Immune Responses in the Central Nervous System following Lethal CVS-11 Infection in Mice

Project description:The microarray and advanced pathway analysis of mice caused a paralysis in a fatal infection of a highly pathogenic CVS-11 was performed for the understanding of the detail gene networks and biological functions of inflammatory response and the related genes of innate immunity and apoptosis. Female BALB/c mice were used at 21 weeks of age. Mice were subcutaneously immunized with UV inactivated SARS-CoV (UV-V) or UV-V and Toll like receptor (TLR) ligands at 6 and 1 weeks prior to mouse-adapted SARS-CoV (n=6 per group). PBS was used in three mice as control immunization. Mice were intranasally challenged with 1E+6TCID50 in 30M-NM-<L. Mice were sacrificed and collected lungs at 1 days after challenge. These mice were used for the analysis of microarray.

SM001: SARS CoV MA15 infection of C57Bl/6 mouse model – Data from 4 viral doses at 1, 2, 4 and 7 days post infection.

Project description:Purpose of experiment was to perform transcriptomic analysis on C57Bl/6 mice infected with different doses of SARS CoV MA15 at 4 different days post infection. Twenty-week-old C57BL/6 mice were infected by intranasal instillation of 10^2, 10^3, 10^4 or 10^5 PFU of SARS CoV MA15 in 50 µl of PBS or mock-infected with PBS alone. At days 1, 2, 4 and 7 days post-infection, lungs were harvested and total RNA was isolated and subjected to microarray analysis. The experimental design was for 4- 5 mice/time point/dose and 3 time-matched mocks. The NIAID Systems Virology Center

Adenosine deaminase augments SARS-CoV-2 specific cellular and humoral responses in aged mouse models of immunization and challenge

Project description:Aged patients suffer disproportionately increased morbidity and mortality associated with SARS-CoV-2 infection. Despite numerous clinically available vaccines and therapeutics, aged patients remain at increased risk for COVID-19 morbidity. Furthermore, the aged patient population has suboptimal responses to SARS-CoV-2 vaccine antigens. Here, we characterize vaccine-induced responses to SARS-CoV-2 synthetic DNA vaccine antigens in 18-month-old mice and interrogate protection. Aged mice have altered cellular responses, including decreased IFNγ secretion and increased TNFα secretion as compared to young mice. Aged mice had significantly decreased binding and neutralizing antibodies in their serum compared to their young counterparts. Co-immunization with the plasmid-encoded molecular adjuvant adenosine deaminase-1 (pADA) enhanced cellular responses and expanded the breadth of humoral responses in aged mice. pADA co-delivery also altered the gene expression profiles of lymph node lymphocytes in aged animals. Upon challenge pADA co-immunization modestly decreased age-associated morbidity and mortality in ACE2 transgenic and mouse-adapted SARS-CoV-2 challenge models. These data support the use of aged mice as a model for age-associated decreased vaccine immunogenicity and infection-mediated morbidity and mortality in the context of SARS-CoV-2 and provide further support of the use of adenosine deaminase as a molecular adjuvant.

Pathogenic role of alarmin IL-33 in a mouse model of SARS-CoV-2 infection

Project description:Male WT C57BL/6j mice (stock #000664, age 8-10 wks) and IL-33 knockout (KO) mice (B6 background) were anesthetized via isoflurane, followed by the intranasal infection with mouse adapted SARS-CoV-2 CMA3p20 (5×10^5 PFU). Mock mice were administrated with identical volumes of cell culture medium. Lungs were perfused with cold PBS and were harvested at days 2 and 4 post-infection. Lung RNA was isolated by Qiagen RNeasy Kits, followed by the Poly (A) RNA sequencing. We then performed differential expression analysis, meta-analysis, and gene set enrichment anaylsis using data obtained by RNA-seq of mock, IL-33 KO, and WT SARS-CoV-2-infected mice.

Transcriptome profiling of the lungs of K18-hACE2 mice infected with SARS-CoV-2 wild-type strain or beta variant

Project description:Diverse severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants have emerged since the beginning of COVID-19 pandemic. We investigated the immunological and pathological characteristics of SARS-CoV-2 beta variant of concern (VOC) compared to the ancestral strain. To investigate a broad spectrum of immunological responses and to determine the underlying mechanisms of differentially expressed cytokines, we analyzed the whole transcriptome of lung homogenates from SARS-CoV-2 ancestral strain- and beta variant-infected mice at 4 and 6 dpi.

Transcriptomic analysis of host response to mouse-adapted SARS virus in wild type, STAT1 -/-, and IFNAR1 -/- mouse genetic backgrounds

Project description:The mechanisms by which pulmonary lesions and fibrosis are generated during SARS-CoV infection are not known. Using high-throughput mRNA profiling, we examined the transcriptional response of wild-type (WT), type I interferon receptor knockout (IFNAR1−/−), and STAT1 knockout (STAT1−/−) mice infected with a recombinant mouse-adapted SARS-CoV (rMA15) to better understand the contribution of specific gene expression changes to disease progression. Ten week old 129S6/SvEv wild-type, STAT1−/− (Taconic Farms, Germantown, NY), and IFNAR1−/− mice bred on a 129SvEv background were anesthetized with a ketamine and infected intranasally with either phosphate-buffered saline (PBS) alone (Invitrogen, Carlsbad, CA) or 1 × 10^5 PFU rMA15-PBS. Mice were euthanized and left lungs were harvested from individual mice (a total of 3 infected mice from each strain) at days 2, 5, and 9 postinfection (dpi) for microarray analyses. Lung samples were taken from mock-infected animals from each of the strains at 5 dpi.
