Project description:Non-canonical microRNAs (miRNAs) are a class of short endogenous RNA molecules with the ability to control development, autophagy, apoptosis and the stress response in eukaryotes by pairing with partially complementary sites in the 3' untranslated regions (UTRs) of targeted genes. Recent studies have demonstrated that miRNAs serve as critical effectors in intricate networks of host-pathogen interactions. Thereforce, the differential expression of miRNAs were evaluated in Madin-Darby bovine kidney (MDBK) cells infected with bovine viral diarrhea virus (BVDV) NADL (100 TCID50/ 0.1 ml) for 6 h compared to normal MDBK cells using Solexa high-throughput sequencing technology (BGI, China).

Project description:Bovine viral diarrhea virus (BVDV) belongs to the Flaviviridae family and the Pestivirus genus. Infection with BVDV causes a disease with a wide spectrum of clinical symptoms, most often mild, although infections with this virus constitute a serious economic problem all over the world. The virus is characterized by a high genetic variability, while the accumulation of single mutations leads to the formation of its new variants. The aim of this study was to better understand the complicated pathogenesis of this disease at the molecular level via the analysis of the transcriptome of cells infected with this virus. The bovine kidney cell line (MDBK), the cytopathic (cp) reference strain, and two non-cytopathic (ncp) BVD virus field strains were used in transcriptomic studies. The cell transcriptome was tested 24 and 72 h after infection. The results of the microarray analysis revealed changes in the expression levels of numerous genes. Genes with changed expression as a result of infection with the cp strain caused changes in the expression levels of a large number of genes and enriched a number of pathways. Genes with increased expression levels were enriched among other pathways involved in the cell cycle, while genes with reduced expression levels enriched pathways mostly related to metabolism. Genes with increased expression levels as a result of infection with ncp strains enriched a much smaller number of pathways, among them, pathways related to signaling activity 24 h post-infection and serine biosynthetic pathways both 24 and 72 h post-infection. Pathways enriched by genes with reduced expression levels were related to the innate immune response (72 h post-infection) or metabolism (24 and 72 h post-infection). The results of microarray studies can help us to better understand the host's response to BVDV infection.

Project description:Bovine viral diarrhea virus (BVDV), a Flaviviridae pestivirus, is arguably one of the most widespread cattle pathogens worldwide. Each of its two genotypes has two biotypes, non-cytopathic (ncp) and cytopathic (cp). Only the ncp biotype of BVDV may establish persistent infection in the fetus when infecting a dam early in gestation, a time point which predates maturity of the adaptive immune system. Such fetuses may develop and be born healthy but remain infected for life. Due to this early initiation of fetal infection and to the expression of interferon antagonistic proteins, persistently infected (PI) animals remain immunotolerant to the infecting viral strain. Although only accounting for some 1% of all animals in regions where BVDV is endemic, PI animals ensure the viral persistence in the host population. These animals may, however, develop the fatal mucosal disease, which is characterized by widespread lesions in the gastrointestinal tract. Cp BVD virus, in addition to the persisting ncp biotype, can be isolated from such animals. The cp viruses are characterized by unrestrained genome replication, and their emergence from the persisting ncp ones is due to mutations that are unique in each virus analyzed. They include recombinations with host cell mRNA, gene translocations and duplications, and point mutations. Cytopathic BVD viruses fail to establish chains of infection and are unable to cause persistent infection. Hence, these viruses illustrate a case of "viral emergence to extinction" - irrelevant for BVDV evolution, but fatal for the PI host.

Project description:Bovine Viral Diarrhea Virus (BVDV) is an endemic virus of North American cattle populations with significant economic and animal health impacts. While BVDV infection has a myriad of clinical manifestations, a unique and problematic outcome is the establishment of a persistently infected (PI) animal following in-utero viral infection. While it is well established that PI animals serve as a constant reservoir of BVDV, the mechanism for the maintained infection remains unknown despite multiple theories. The purpose of this study was to use transcriptome analysis to further define long term immune status of adult PI cattle and offer insight into the potential mechanistic establishment of persistent BVDV infection, in utero. Peripheral blood mononuclear cells were collected from PI beef cattle (N=6) and uninfected controls (N=6) for targeted RNAseq analysis conducted using 54 genes of interest and followed by pathway enrichment analysis. Analysis revealed 29 differentially expressed genes (FDR < 0.05, fold change > 2) representing 14 significant KEGG pathways between PI and control animals (FDR < 0.05). Transcriptome changes indicate chronic upregulation of interferon gamma (IFNG) with unexpected expression of related genes, suggesting a maintained stimulation of the PI immune system resulting in virus-mediated dysregulation of immune function.

Project description:The impact of late-term fetal bovine viral diarrhea virus (BVDV) transient infections (TI) on fetal growth and methylome was examined by inoculating pregnant heifers with a noncytopathic (ncp) type 2 BVDV suspended in media or media alone (sham-inoculated controls) on day 175 of gestation to generate TI (n=11) and control heifer calves (n=12). Blood samples were collected at birth. White blood cells (WBC) were separated for DNA extraction. Fetal infection in calves was confirmed by positive virus serum neutralizing antibody titers at birth and control calves were seronegative. Both control and TI calves were negative for BVDV RNA in WBCs by RT-PCR. DNA methyl seq analysis of WBC DNA demonstrated 2,349 differentially methylated cytosines (p≤0.05) including 1,277 hypomethylated cytosines, 1.072 hypermethylated cytosines, 84 differentially methylated regions based on CpGs in promoters and 89 DMRs based on CpGs in exons of TI WBC DNA compared to controls. Fetal BVDV infection during late gestation resulted in epigenomic modifications predicted to affect fetal and organ development pathways suggesting potential consequences for postnatal growth and health of TI cattle.

Project description:Bovine viral diarrhea virus (BVDV) belongs to the genus Pestivirus within the family Flaviviridae. Mitophagy plays important roles in virus-host interactions. Here, we provide evidence that non-cytopathic (NCP) BVDV shifts the balance of mitochondrial dynamics toward fission and induces mitophagy to inhibit innate immune responses. Mechanistically, NCP BVDV triggers the translocation of dynamin-related protein (Drp1) to mitochondria and stimulates its phosphorylation at Ser616, leading to mitochondrial fission. In parallel, NCP BVDV-induced complete mitophagy via Parkin-dependent pathway contributes to eliminating damaged mitochondria to inhibit MAVS- and mtDNA-cGAS-mediated innate immunity responses, mtROS-mediated inflammatory responses and apoptosis initiation. Importantly, we demonstrate that the LIR motif of ERNS is essential for mitophagy induction. In conclusion, this study is the first to show that NCP BVDV-induced mitophagy plays a central role in promoting cell survival and inhibiting innate immune responses in vitro.
