Dynamic host-pathogen interactions in pathogen-challenged chicken embryo fibroblasts cells with Marek’s Disease Virus using 3’ end enriched RNA-seq

ABSTRACT: Marek’s disease is a contagious lymphoproliferative disease of chickens and is a unique model of viral oncogenesis. Mapping changes or states over the course of infection for both host and pathogen would have the potential to generate important insights into dynamic host-pathogen interactions. Here we introduced 3’ end enriched RNA-seq as a novel method to study host-pathogen interactions in Marek’s disease virus challenged chicken embryo fibroblasts cells, which allowed accurate profiling of gene expression and alternative polyadenylation sites for host and pathogen simultaneously. We totally identified 476 differentially expressed genes and 437 APA switching genes in host, including switching in tandem 3’ UTRs and switching between coding region and 3’ UTR. Most of these genes were related to innate immunity, apoptosis and metabolism, but two sets of genes overlapped a little suggesting two complementary mechanisms for regulating gene expression during infection. In summary, our results gave a relatively comprehensive insight into dynamic host-pathogen interactions in gene transcription regulation during Marek’s disease virus infection and suggested that 3’ end enriched RNA-seq was a promising method to investigate global host-pathogen interactions.

Transcriptional Profiling of Meq-dependent Genes in Marek’s Disease Resistant and Susceptible Inbred Chicken Lines

Project description:Marek’s disease (MD) is an economically significant disease in chickens caused by the highly oncogenic Marek’s disease virus (MDV). Understanding the genes and biological pathways that confer MD genetic resistance should lead towards the development of more disease resistant commercial poultry flocks or improved MD vaccines. MDV Meq, a bZIP transcription factor, is largely attributed for viral oncogenicity though only a few host target genes have been described, which has impeded our understanding of MDV-induced tumorigenesis. Given the importance of Meq in MDV-induced pathogenesis, we explored the role of Meq in genetic resistance to MDV. Using global transcriptome analysis to compare the host response between birds challenge with either wild type MDV or a recombinant lacking Meq, we identified a number of specific genes and pathways associated with either MD resistance. Integrating prior information from ChIP-seq, microarray analysis, and SNPs exhibiting allele-specific expression (ASE) in response to MDV infection from two inbred layer lines that differ greatly in MD genetic resistance, we were able to provide a evidence for 35 genes that SNPs within transcription factor binding sites can affect transcription factor binding and gene expression in an allele-specific manner.

Time-resolved genome-wide pathogenic gene expression analysis of the plant pathogen Xanthomonas oryzae pv. oryzae (Xoo) via RNA-Seq

Project description:Host-pathogen interactions, in particular during the early stage of infection, are important for the fate of boththe invading pathogen and host. In pathogens, these interactions activate diverse pahogenic signals to cause disease in the host and evade the inevitably activated immune responses of the infected host. In this study, we used in vitro assay system and RNA-seq to analyze the time-resolved genome-wide gene expressions of Xoo evoked by the interactions with rice leaf extracts. RNA-seq analysis was carried out with samples of 3 different time points within 2 hours

Dual spatially resolved transcriptomics for SARS-CoV-2 host-pathogen colocalization studies in humans

Project description:To advance our understanding of cellular host-pathogen interactions, technologies that facilitate the co-capture of both host and pathogen spatial transcriptome information are needed. Here, we present an approach to simultaneously capture host and pathogen spatial gene expression information from the same formalin-fixed paraffin embedded (FFPE) tissue section using the spatial transcriptomics technology. We applied the method to COVID-19 patient lung samples and enabled the dual detection of human and SARS-CoV-2 transcriptomes at 55 Ã‚Âµm resolution. We validated our spatial detection of SARS-CoV-2 and identified an average specificity of 94.92% in comparison to RNAScope and 82.20% in comparison to in situ sequencing (ISS). COVID-19 tissues showed an upregulation of host immune response, such as increased expression of inflammatory cytokines, lymphocyte and fibroblast markers. Our colocalization analysis revealed that SARS-CoV-2+ spots presented shifts in host RNA metabolism, autophagy, NFÃŽÂºB, and interferon response pathways. Future applications of our approach will enable new insights into host response to pathogen infection through the simultaneous, unbiased detection of two transcriptomes.

Evaluating the effect of spaceflight on the host-pathogen interaction between human intestinal epithelial cells and Salmonella Typhimurium

Project description:Spaceflight uniquely alters the physiology of both human cells and microbial pathogens, stimulating cellular and molecular changes directly relevant to infectious disease. However, the influence of this environment on host-pathogen interactions remains poorly understood. Here we report our results from the STL-IMMUNE pilot study flown aboard STS-131, which investigated multi-omic responses (transcriptomic, proteomic) of human intestinal epithelial cells to infection with Salmonella Typhimurium when both host and pathogen were simultaneously exposed to spaceflight. To our knowledge, this is the first in vitro in-flight infection and dual RNA-seq analysis using human cells.

Arhgdia regulates disease tolerance in IAV-infected epithelial cells

Project description:When challenged with an invading pathogen, host defense mechanisms are engaged to eliminate the pathogen (resistance) and limit tissue damage that results from host-pathogen interactions (disease tolerance). We identified Arhgdia as a driver of the molecular disease-tolerance response in epithelial cells. The effect of Arhgdia on disease tolerance and resistance was evaluated at early stages of influenza A virus (IAV) infection. Our observations indicates that Arhgdia has an effect on disease tolerance during IAV infection.

RNA-seq-based analysis of the pathogen-induced defense transcriptome in Arabidopsis

Project description:Pathogen infection triggers transcriptional reprogramming in host plants, however we still know little about the dynamics of the pathogen-induced defense transcriptome. The goal of this study was to investigate the dynamic reprogramming of the defense transcriptome in response to Fusarium oxysporum infection in Arabidopsis using RNA-seq technology and to provide a comprehensive analysis of genes underlying the innate immune response against the fungal pathogen. Our results suggest that the Arabidopsis transcriptome is reprogrammed to co-ordinately express multiple positive and negative regulators following pathogen infection to modulate defense gene expression and disease resistance. Our study identified a number of novel genes responsive to pathogen infection and provided a rich source of pathogen responsive genes for further functional characterization.

Simultaneous host-pathogen transcriptional analysis of Clostridium perfringens murine myonecrosis infections

Project description:To obtain an insight into host-pathogen interactions in clostridial myonecrosis, we carried out comparative RNA-seq analysis measuring host genes in a murine C. perfringens infection model. Analysis of the murine transcriptome from infected muscle tissues indicated that 270 genes were up-regulated compared to control mock-infected mice. KEGG pathway analysis of these genes revealed an enrichment of Toll-like receptor (TLR) and Nod-like receptor (NLR) signaling components.

An in vivo atlas of host-pathogen transcriptomes during Streptococcus pneumoniae colonization and disease

Project description:D’Mello et al. detail host-pathogen interaction gene expression profiles of Streptococcus pneumoniae (Spn) and its infected host at disease relevant anatomical sites using mice as experimental models. The authors identify the core and organ-specific transcriptomes of Spn, show that bacterial and host gene expression profiles are highly distinct during asymptomatic colonization versus disease-causing infection, and demonstrate that Spn and host genes with high levels of expression contribute to pathogenesis or host defense, respectively.
