RNA-seq of coronavirus infected and treated mouse lungs

ABSTRACT: An infection with SARS-CoV-2 can be symptomatic or asymptomatic depending on the respective activation of the immune system. We used the bacterial extract Broncho Vaxom (BV) to preactivate the immune system before a coronavirus infection using the murine coronavirus MHV A59 in a mouse model. The activation of the immune system led to a reduction in viral load and protected lung tissue from enhanced cell apoptosis. Using RNA sequencing we were able to demonstrate that lung tissue from mice receiving BV resembled an intermediate state between infected and healthy tissue. On a cellular level, treatment with BV enhanced alveolar and interstitial macrophages in the lung. We were able to phenocopy the effect of BV by transplanting naïve lung macrophages into recipient mice thereby enhancing the local cellular amount before infection. We conclude that recruitment and preactivation of the innate immune system by the bacterial extract BV is beneficial during a coronavirus infection.

Transcriptomic landscape of murine coronavirus infection in the lung

Project description:Impaired type I interferon (IFN) responses are predictive of severe disease during pulmonary coronavirus infection. Insufficient IFN-responsiveness is associated with viremia and hypercytokinemia, however the resolution of IFN-dependent innate immune responses in the lungs remains limited. Here, we aimed to elucidate the early dynamics of antiviral immunity and define the IFN-dependent mechanisms limiting viral spread during pulmonary infection with the murine coronavirus A59 (M-CoV-A59), a beta-coronavirus. Combining high-resolution transcriptomic analysis and genetic attenuation of interferon signaling, we delineated IFN-dependent cell-intrinsic and population-based transcriptional changes that determined viral replication and inflammatory maturation, respectively.

Transcription profiling of mouse fibroblasts infected with murine hepatitis virus using two array platforms to compare the potential for interference from viral RNA

Project description:Infection of cells with murine hepatitis virus strain A59 (MHV-A59) results in massive amounts of viral RNA within infected cells. When applying transcriptional profiling by means of microarray analysis, this could potentially cause problems since high amounts of viral RNA could in theory interfere with the analysis. Since coronavirus RNAs are polyadenylated, the viral RNAs are also amplified by oligo(dT) primers (a standard procedure when processing RNA samples for array hybridization). In this experiment we compared two different array platforms for the potential interference of viral RNA, using MHV-A59 infection of LR7 (murine fibroblasts) as a model.

Analysis of coronavirus and infected host-cell gene expression through RNA sequencing and ribosome profiling

Project description:Ribosome profiling (RiboSeq) (maps positions of translating ribosomes on the transcriptome) and RNASeq (quantifies the transcriptome) analysis of murine 17 clone 1 (17Cl-1) cells infected with Murine coronavirus strain A59 (MHV-A59). Samples comprise 1 and 8 h mocks, 1, 2.5, 5 and 8 h post infection timecourse, for each of RiboSeq with cycloheximide (CHX), RiboSeq with harringtonine (HAR), and RNASeq, performed in duplicate (6 x 3 x 2 libraries); RiboSeq CHX, RiboSeq HAR and RNASeq at 1 h post infection for high multiplicity of infection (3 libraries); and 1 \long-read\ library for 5 h post infection RiboSeq CHX to test for larger-than-normal ribosome footprints.

Ketogenesis restrains aging-induced exacerbation of COVID in a mouse model (scRNA-seq)

Project description:Impaired immunometabolic response in the elderly regulates inflammation-driven COVID-19 severity which confers the greatest risk of mortality. To investigate how aging compromises defense against COVID-19, we developed a model of natural murine beta coronavirus (mCoV) infection with mouse hepatitis virus strain A59 (mCoV-A59) that recapitulated majority of hallmarks of COVID-19. Aged mCoV-A59-infected mice have increased mortality and higher systemic inflammation in the heart, adipose tissue and hypothalamus, including neutrophilia and loss of γδ T cells in lungs. Ketogenic diet increases beta-hydroxybutyrate, expands tissue protective γδ T cells, deactivates the inflammasome and decreases pathogenic monocytes in lungs during aging. These data underscore the value of mCoV-A59 model to test mechanism and establishes harnessing of ketogenic immunometabolic checkpoint as potential treatment against COVID-19 in the elderly.

Comparative transcriptomic analysis of Gardnerella vaginalis biofilms versus planktonic cultures using RNA-seq

Project description:Bacteria assume distinct lifestyles during the planktonic and biofilm modes of growth. In biofilms, they are more tolerant to antibiotics and can evade the immune system response more effectively. However, little is known regarding the molecular determinants involved in biofilm formation by Gardnerella vaginali, the predominant species found in bacterial vaginosis (BV). Hence, to gain insight into the pathogenesis of G. vaginalis, we carried out a comparative transcriptomic analysis between planktonic and biofilm phenotypes, using RNA-sequencing. The major alterations observed were related with the transcription of genes involved in cell wall biogenesis and typical stress factors, in which was found significantly up-regulated in biofilms, resulting in a protected mode of bacterial growth. In addition, biofilm phenotype was characterized by low metabolic activity, which is appropriate to guarantee long term survival during BV recurrence.

Kinetics of progressive pulmonary cavitary TB disease in rabbits

Project description:Every year, tuberculosis kills nearly 1.8 million people through out the world. Though outcome of M. tuberculosis infection into active disease is determined by the host and bacterial factors, a strong host immune response controls the growth of the bacilli effectively. However, in a host with suboptimal immune response, the bacilli grows and mounts active disease. Activation of immune response following M. tuberculosis infection affects the expression of many host genes that are involved in the production of immune system molecules such as cytokines, chemokines, surface receptors and transcriptional regulators that manifest in the change of subsequent cellular events, including activation, maturation, chemotaxis and proliferation of effector cells. However, the specific nature of the host-pathogen interactions and the outcome of Mtb infection are not fully understood. In this study, we have analysed the systematic changes in the global host gene expression profile in the lungs of Mtb infected rabbits at various stages of infection. Mtb infected rabbit lung tissues were isolated at T=0,2, 4 and 16 weeks post-infection. Lung bacterial load, histologic changes and host and bacterial gene expression were determined for each timepoint and compared . Our data suggests a strong correlation between the significant changes in the global transcriptome of infected rabbits and the progression of Mtb infection into a chronic, cavitary TB disease. The microarray experiments involves comparison of: 1) Changes in rabbit gene expression between Mtb-HN878 infected and uninfected animals at 2,4 and 16 weeks post infection. New Zealand White rabbits were infected with Mtb HN878 at 3.2log10 (on day 0). Lung tissue from Mtb-infected rabbits were isolated at Day0, 2, 4 and 16 weeks post infection and used for total RNA extraction.

An herbal medicine-based formula affected the epithelial cell line, BEAS-2B, genes expression.

Project description:Coronavirus Disease 2019 (COVID-19) remains a threat on the fatal ARDS with an incidence rate of 41.8%, or irreversible pulmonary fibrosis, without specific effective therapeutic drugs. The infection causes dysregulation of the immune system with a cytokine storm in lung tissue. To define the drug candidate of Virofree to COVID-19 induced-ARDS, we treated 66.67 ug/ml and 500 ug/ml in epithelial cell line, BEAS-2B, and compared the PBS control group to obtain Virofree expression profiles.

Gene Expression Timecourse of WT, DUBmut, and EndoUmut Mouse Hepatitis Virus Strain A59 infected C57bl/6 Bone Marrow derived macrophages

Project description:We report the differences in innate immune activation in the comparison of wild type and mutant Mouse Hepatitis Virus Strain A59 infection of bone marrow derived macrophages. We infected BMDMs and harvested RNA at 3, 6, 9, and 12 hpi while comparing changes in host gene expression compared to mock infected cells. Here, using a transcriptomics approach, we compared the scope and kinetics of the host response to the wild type, DUBmut, and EndoUmut viruses in infected macrophages. We found that the EndoUmut virus activates a focused response, predominantly involving type I interferons and a subset of interferon-responsive genes, within 12 hours after infection. In contrast, the wild type and DUBmut viruses stimulate the upregulation of over 2,800 genes, including the activation of unfolded protein response (UPR) pathways and a proinflammatory response associated with viral pathogenesis. This study highlights the role of viral interferon antagonists in modulating the kinetics and magnitude of the host response during virus infection and demonstrates that inactivation of a dominant viral antagonist, the coronavirus endoribonuclease, dramatically alters the host response in macrophages and the disease process.
