Transcriptome Profiling of PRRSV Infected Porcine Alveolar Macrophages By Single Cell Sequencing

ABSTRACT: Porcine reproductive and respiratory syndrome (PRRSV) is a devastating pathogen for the pig industry worldwide. PRRSV mainly infects porcine alveolar macrophage (PAM). In the present study, single-cell RNA sequencing (scRNA-seq) was employed to characterize the host transcriptome responses of PAMs infected with a virulent PRRSV strain in vivo and ex vivo. Increase ofpro-inflammatory and anti-apoptotic genes was correlated with the increase of infection (expression of the virus ORF7 transcript).

PRRSV counteracts type I interferon-induced antiviral state

Project description:Porcine reproductive and respiratory syndrome (PRRS) is an economically important disease with a significant impact on the pig industry. It is caused by PRRS virus (PRRSV), which predominantly infects and replicates in porcine pulmonary alveolar macrophages (PAMs), providing a useful in vitro model for understanding the host immune response to PRRSV infection. We pretreated PAMs with porcine IFN-α to induce an antiviral state within the cells and subsequently infected them with highly pathogenic (HP)-PRRSV. Changes in global gene expression in IFN-α-pretreated PAMs in response to HP-PRRSV infection were determined by RNA-sequence analysis. A total of 346 differentially expressed genes (DEGs) were transcriptionally upregulated by porcine IFN-α. Among these up-regulated DEGs, 93 showed significantly attenuated expression levels in response to HP-PRRSV infection. These attenuated DEGs were remarkably enriched in immune-response-related terms, such as 'RIG-Ilike receptor signaling pathway', 'Response to virus', and 'Response to stimulus'. Notably, expression levels of 93.8% (15/16) of antiviral genes (such as PKR, OAS1, IFIT1(ISG56) and ISG15), and genes encoding retinoic-acid-inducible gene-I protein (LOC100737466(DDX58), a cytoplasmic viral RNA sensor), interferon regulatory factor 7 (IRF7, a key transcriptional regulator of type I IFN-dependent immune response), signal transducer and activator of transcription 1 (LOC100738308(STAT1), a transcription factor for IFN-stimulated genes), and tumor necrosis factor-related apoptosis-inducing ligand (TNFSF10, a cytokine initiating proapoptotic signaling cascades) were significantly attenuated by HP-PRRSV infection. These results suggest that HP-PRRSV can counteract the type I IFN-induced antiviral state by interfering with the expression of genes involved in the host-defense response.

Transcriptome analysis of a PRRSV-infected and control PAMs

Project description:Transcriptomes analysis of long noncoding RNA (lncRNA) and mRNA expression profiles of the porcine alveolar macrophages (PAMs) after porcine reproductive and respiratory syndrome virus (PRRSV) infection in vitro. We obtained 105,627,026 clean reads from 109,443,286 raw reads. A total of 951 annotated and 751 novel lncRNAs were identified. PAMs showed distinct transcriptome profiles after PRRSV infection. It was observed that 126 lncRNAs and 753 mRNAs were differentially expressed between PRRSV-infected and control group PAMs.

Quantitative proteomic analysis of global protein acetylation in PRRSV infected pulmonary alveolar macrophages

Project description:Porcine reproductive and respiratory syndrome (PRRS), which caused by the porcine reproductive and respiratory syndrome virus (PRRSV), is a serious viral disease affecting global swine industry. At present, PRRSV vaccines fail to prevent this disease. Consequently, new antiviral strategies to compensate for the inefficacy of available vaccines are urgently required. Lysine acetylation is an important post-translational modification (PTM) regulating an array of pathological and physiological conditions. In this study, we profiled the global acetylome using acetylation specific antibody based enrichment and Tandem mass tag (TMT) label LC-MS in PRRSV-infected pulmonary alveolar macrophages (PAMs). As a result, 3731 lysine acetylation sites on 1421 cellular proteins were identified and quantified 6 hours post infection (hpi). Bioinformatics analysis of the differentially acetylated proteins revealed their involvement in various biological processes, including the host immune response and energy metabolism.

PRRSV-infection of porcine alveolar macrophages

Project description:The goal of this study was to produce a deep, global analysis of gene expression changes that occured following infection of normal porcine alveolar macrophages (PAMs) with PRRSV. The goal was to examine the gene expression changes to help determine the mechanisms that result in reduced function and immunosuppression observed in PRRSV-infected pigs. Keywords: time course of infection The PAMs were infected in culture at an MOI of 10 with PRRSV strains VR-2332 and incubated at 37C until 6, 12, 16 or 24 hours post infection. Total cellular RNA was collected from each at the appropriate time. SAGE libraries were prepared from each infected time point as well as from noninfected PAMs. The SAGE libraries were sequenced to at least 95,000 tags each.

Gene expression profiles for porcine alveolar macrophage isolated from piglets injected with Mab followed by challenge with two PRRSV strains: PRRSV-JXA1 and PRRSV-HNhx

Project description:An PRRSV specific IgG-type Mab-PN9cx3, demonstrated broad recognition and neutralization activity against both PRRSV-1 and PRRSV-2 isolates in vitro, was tested for in vivo protection experiments. Administration of Mab-PN9cx3 20mg in piglets significantly alleviated the pathological changes in lungs and decreased virus loads in PAMs after challenging with two heterogenous PRRSV isolates: HP-PRRSV-JXA1 and PRRSV NADC-30 like HNhx when compared with piglets inoculated virus . Transcriptome profile for porcine alveolar macrophage of different groups were analyzed via RNA-sequencing.

Pulmonary alveolar macrophages (PAMs) of Tongcheng piglets response to HP-PRRSV infection in vivo

Project description:Porcine reproductive and respiratory syndrome (PRRS), caused by PRRS virus (PRRSV), is the most economically important disease in pig populations. Lung damage is one major pathological condition following PRRSV infection, often leading to animal death. In vivo, PRRSV productive infection occurs predominately in alveolar macrophages of the lung. Here, transcriptome profiling of pulmonary alveolar macrophages (PAMs) from Tongcheng piglets pre- and post- infection of highly pathogenic PRRSV has been performed using porcine Affymetrix GeneChip.

Genome-wide transcriptional response of primary alveolar macrophages (PAMs) following infection with porcine circovirus type 2

Project description:Porcine alveolar macrophages (PAMs) play impoartant role in innate immunity. Porcine circovirus type 2 (PCV2) has been identified as the causal agent of postweaning multisystemic wasting syndrome, an economically important multifactorial disease of the swine industry worldwide. We used microarrays to study the transcriptome of PAMs infection with PCV2. PAMs were collected by bronchoalveolar lavage from health piglets (free of PCV2, PRRSV, PRV, CSFV, PPV), and PAMs were cultured for 48 hours and inoculated with 5 moi of PCV2.
