Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) causes respiratory disease in pigs of all ages and reproductive failure in sows, resulting in great economic losses to the swine industry. In this work, we identified the interaction between PSMB4 and PRRSV Nsp1α by yeast two-hybrid screening. The PSMB4-Nsp1α interaction was further confirmed by coimmunoprecipitation, glutathione S-transferase (GST) pulldown, and laser confocal experiments. The PCPα domain (amino acids 66 to 166) of Nsp1α and the C-terminal domain (amino acids 250 to 264) of PSMB4 were shown to be critical for the PSMB4-Nsp1α interaction. PSMB4 overexpression reduced PRRSV replication, whereas PSMB4 knockdown elicited opposing effects. Mechanistically, PSMB4 targeted K169 in Nsp1α for K63-linked ubiquitination and targeted Nsp1α for autolysosomal degradation by interacting with LC3 to enhance the activation of the lysosomal pathway. Meanwhile, we found that PSMB4 activated the NF-κB signaling pathway to produce type I interferons by downregulating the expression of IκBα and p-IκBα. In conclusion, our data revealed a new mechanism of PSMB4-mediated restriction of PRRSV replication, whereby PSMB4 was found to induce Nsp1α degradation and type I interferon expression, in order to impede the replication of PRRSV. IMPORTANCE In the swine industry, PRRSV is a continuous threat, and the current vaccines are not effective enough to block it. This study determined that PSMB4 plays an antiviral role against PRRSV. PSMB4 was found to interact with PRRSV Nsp1α, mediate K63-linked ubiquitination of Nsp1α at K169, and thus trigger its degradation via the lysosomal pathway. Additionally, PSMB4 activated the NF-κB signaling pathway to produce type I interferons by downregulating the expression of IκBα and p-IκBα. This study extends our understanding of the proteasome subunit PSMB4 against PRRSV replication and will contribute to the development of new antiviral strategies.

Genome-Wide mRNA and Long Non-Coding RNA Analysis of Porcine Trophoblast Cells Infected with Porcine Reproductive and Respiratory Syndrome Virus Associated with Reproductive Failure. Int J Mol Sci 2023; 24:ijms24020919. [PMID: 36674446 PMCID: PMC9866684 DOI: 10.3390/ijms24020919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/30/2022] [Accepted: 12/31/2022] [Indexed: 01/06/2023] Open
Abstract
Porcine reproductive and respiratory syndrome (PRRS) is a vertically transmitted reproductive disorder that is typically characterized by miscarriage, premature birth, and stillbirth in pregnant sows after infection. Such characteristics indicate that PRRSV can infect and penetrate the porcine placental barrier to infect fetus piglets. The porcine trophoblast is an important component of the placental barrier, and secretes various hormones, including estrogen and progesterone, to maintain normal pregnancy and embryonic development during pregnancy. It is conceivable that the pathogenic effects of PRRSV infection on porcine trophoblast cells may lead to reproductive failure; however, the underlying detailed mechanism of the interaction between porcine trophoblast (PTR2) cells and PRRSV is unknown. Therefore, we conducted genome-wide mRNA and long non-coding RNA (lncRNA) analysis profiling in PRRSV-infected PTR2. The results showed that 672 mRNAs and 476 lncRNAs were significantly different from the control group after viral infection. Target genes of the co-expression and co-location of differential mRNAs and lncRNAs were enriched by GO (gene ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) analysis, revealing that most of the pathways were involved in cell nutrient metabolism, cell proliferation, and differentiation. Specifically, the estrogen signaling pathway, the PI3K (PhosphoInositide-3 Kinase)-Akt (serine/threonine kinase) signaling pathway, and the insulin secretion related to embryonic development were selected for analysis. Further research found that PRRSV inhibits the expression of G-protein-coupled estrogen receptor 1 (GPER1), thereby reducing estrogen-induced phosphorylation of AKT and the mammalian target of rapamycin (mTOR). The reduction in the phosphorylation of AKT and mTOR blocks the activation of the GPER1- PI3K-AKT-mTOR signaling pathway, consequently restraining insulin secretion, impacting PTR2 cell proliferation, differentiation, and nutrient metabolism. We also found that PRRSV triggered trophoblast cell apoptosis, interrupting the integrity of the placental villus barrier. Furthermore, the interaction network diagram of lncRNA, regulating GPER1 and apoptosis-related genes, was constructed, providing a reference for enriching the functions of these lncRNA in the future. In summary, this article elucidated the differential expression of mRNA and lncRNA in trophoblast cells infected with PRRSV. This infection could inhibit the PI3K-AKT-mTOR pathway and trigger apoptosis, providing insight into the mechanism of the vertical transmission of PRRSV and the manifestation of reproductive failure.

Abstract
Porcine reproductive and respiratory syndrome (PRRS) is an infectious disease characterized by severe reproductive failure in sows, acute respiratory disorders in growing pigs, and high mortality in piglets. The causative agent of this syndrome is the PRRS virus (PRRSV), an RNA virus belonging to the Arteriviridae family. To date, several quantitative approaches of proteomics have been applied to analyze the gene expression profiles during PRRSV infection in PAMs and MARC-145 cells, and few proteins have been consistent among independent studies, probably due to the differences in the levels of virulence of different PRRSV strains used and/or due to analytical conditions. In this study, total proteins isolated from noninfected and infected MARC-145 cells with a Mexican PRRSV strain were relatively quantified using label-free based DIA approach in combination with ion-mobility separation. As a result, 1456 quantified proteins were found to be shared between the control and infected samples. Afterward, these proteins were filtered, and 699 of them were considered without change. Also, 17 proteins were up-regulated and 19 proteins were down-regulated during the PRSSV infection. Bioinformatic analysis revealed that many of the differentially expressed proteins are involved in processes like antigen processing, presentation of antigens, response to viruses, response to IFNs, and innate immune response, among others. The present work is the first one which provides a detailed proteomic analysis through label-free based DIA approach in MARC-145 cells during the infection with a Mexican PRRSV strain.

Abstract
Porcine epidemic diarrhea virus (PEDV), a swine enteropathogenic coronavirus (CoV), is the causative agent of porcine epidemic diarrhea (PED). PED causes lethal watery diarrhea in piglets, which has led to substantial economic losses in many countries and is a great threat to the global swine industry. Interferons (IFNs) are major cytokines involved in host innate immune defense, which induce the expression of a broad range of antiviral effectors that help host to control and antagonize viral infections. PEDV infection does not elicit a robust IFN response, and some of the mechanisms used by the virus to counteract the host innate immune response have been unraveled. PEDV evades the host innate immune response by two main strategies including: (1) encoding IFN antagonists to disrupt innate immune pathway, and (2) hiding its viral RNA to avoid the exposure of viral RNA to immune sensors. This review highlights the immune evasion mechanisms employed by PEDV, which provides insights for the better understanding of PEDV-host interactions and developing effective vaccines and antivirals against CoVs.

Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV), an acute infectious disease agent in swine, causes enormous economic losses to the global swine industry. PRRSV nonstructural protein 1β (nsp1β) plays a critical role in viral subgenomic mRNA synthesis and host immune regulation. However, the global changes of cellular gene expression in natural target cells regulated by the nsp1β have not yet been identified. Here, isobaric tags for relative and absolute quantification (iTRAQ) labeling coupled with liquid chromatography-tandem mass spectrometry were used to quantitatively identify cellular proteins in porcine alveolar macrophage (PAM) 3D4/21 cells transduced with recombinant lentivirus expressing PRRSV nsp1β that are differentially expressed compared with PAM 3D4/21 cells transduced with recombinant lentivirus expressing GFP. Of the 425 cellular proteins detected as differentially expressed, 186 were upregulated and 239 were downregulated. Based on the identities of the differentially expressed cellular proteins and the essential role of nsp1β in interferon (IFN) activation and inflammatory factor antagonism during PRRSV infection, we propose a potential mechanism in which nsp1β inhibits IFN induction and nuclear factor κB (NF-κB) signaling pathways. Our results suggest that mitochondrial antiviral signaling (MAVS) protein and translocases of outer membrane complex 70 (TOM70), involved in type I IFN induction, were downregulated, while protein phosphatase 1A (PPM1A), related to the inhibition of NF-κB pathway activation, was upregulated in nsp1β-overexpressed PAM 3D4/21 cells. These data provide valuable information for better understanding the potential biological function of nsp1β during PRRSV infection and the mechanism of virus escape from host immune surveillance of viral replication.

Abstract
Canine distemper virus (CDV), a paramyxovirus, causes a severe highly contagious lethal disease in carnivores, such as mink. Mink lung epithelial cells (Mv.1.Lu cells) are sensitive to CDV infection and are homologous to the natural host system of mink. The current study analyzed the response of Mv.1.Lu cells to CDV infection by iTRAQ combined with LC-MS/MS. In total, 151 and 369 differentially expressed proteins (DEPs) were markedly up-regulated or down-regulated, respectively. Thirteen DEPs were validated via real-time RT-PCR or western blot analysis. Network and KEGG pathway analyses revealed several regulated proteins associated with the NF-κB signaling pathway. Further validation was performed by western blot analysis and immunofluorescence assay, which demonstrated that different CDV strains induced NF-κB P65 phosphorylation and nuclear translocation. Moreover, the results provided interesting information that some identified DEPs possibly associated with the pathogenesis and the immune response upon CDV infection. This study is the first overview of the responses to CDV infection in Mv.1.Lu cells, and the findings will help to analyze further aspects of the molecular mechanisms involved in viral pathogenesis and the immune responses upon CDV infection.

Abstract
Significant differences exist between the highly pathogenic (HP) porcine reproductive and respiratory syndrome virus (PRRSV) and its attenuated pathogenic (AP) strain in the ability to infect host cells. The mechanisms by which different virulent strains invade host cells remain relatively unknown. In this study, pulmonary alveolar macrophages (PAMs) are infected with HP‐PRRSV (HuN4) and AP‐PRRSV (HuN4‐F112) for 24 h, then harvested and subjected to label‐free quantitative MS. A total of 2849 proteins are identified, including 95 that are differentially expressed. Among them, 26 proteins are located on the membrane. The most differentially expressed proteins are involved in response to stimulus, metabolic process, and immune system process, which mainly have the function of binding and catalytic activity. Cluster of differentiation CD163, vimentin (VIM), and nmII as well as detected proteins are assessed together by string analysis, which elucidated a potentially different infection mechanism. According to the function annotations, PRRSV with different virulence may mainly differ in immunology, inflammation, immune evasion as well as cell apoptosis. This is the first attempt to explore the differential characteristics between HP‐PRRSV and its attenuated PRRSV infected PAMs focusing on membrane proteins which will be of great help to further understand the different infective mechanisms of HP‐PRRSV and AP‐PRRSV.

Abstract
Heat shock protein 27 (HSP27), functioning as a stress induced protective protein, has been reported to participate in various biological processes, including apoptosis, thermal protection, and virus infection. In this study, a HSP27-like gene from the seawater fish sea perch, designated as LjHSP27, was characterized. The 1361 bp full-length cDNA of LjHSP27 encoded a 221 amino acid protein containing a conserved α-crystallin domain, two variable amino- and carboxy-terminal extensions, a WD/EPF motif, two serine phosphorylation sites, and two putative actin binding regions. Phylogenetic analysis showed that LjHSP27 shared the closest genetic relationship with HSP27 of the Asian seabass Lates calcarifer. LjHSP27 mRNA was ubiquitously expressed in all tissues examined, but significantly up-regulated in spleen and kidney and down-regulated in brain post red spotted grouper nervous necrosis virus (RGNNV) infection. In vitro, LjHSP27 transcript was remarkably reduced post RGNNV infection, but rapidly increased after polyinosinic-polycytidylic acid treatment. Up-regulation and down-regulation of LjHSP27 inhibited and promoted RGNNV replication in cultured LJB cells, respectively. Luciferase assay indicated that LjHSP27 could enhance the promoter activities of zebrafish interferon (IFN)1 and IFN3, suggesting its potential role in innate immune responses. Moreover, overexpression of LjHSP27 inhibited RGNNV-induced apoptosis, as indicated by the up-regulation of anti-apoptotic genes and down-regulation of pro-apoptotic genes, while KNK437 caused down-regulation of LjHSP27 dramatically led to opposite results, suggesting that LjHSP27 might exert its anti-RGNNV activities by regulating the apoptosis signaling pathway. Our results would provide a new insight into the underlying molecular mechanism of HSP and RGNNV interaction.

Genome-wide analysis of long noncoding RNA profiling in PRRSV-infected PAM cells by RNA sequencing. Sci Rep 2017; 7:4952. [PMID: 28694521 PMCID: PMC5504012 DOI: 10.1038/s41598-017-05279-z] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2016] [Accepted: 05/26/2017] [Indexed: 12/27/2022] Open
Abstract
Porcine reproductive and respiratory syndrome (PRRS) is a major threat to the global swine industry and causes tremendous economic losses. Its causative agent, porcine reproductive and respiratory syndrome virus (PRRSV), primarily infects immune cells, such as porcine alveolar macrophages and dendritic cells. PRRSV infection results in immune suppression, antibody-dependent enhancement, and persistent infection. Highly pathogenic strains in China cause high fever and severe inflammatory responses in the lungs. However, the pathogenesis of PRRSV is still not fully understood. In this study, we analysed the long noncoding RNA (lncRNA) and mRNA expression profiles of the HP-PRRSV GSWW15 and the North American strain FL-12 in infected porcine alveolar macrophages (PAMs) at 12 and 24 hours post-infection. We predicted 12,867 novel lncRNAs, 299 of which were differentially expressed after viral infection. The Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) analyses of the genes adjacent to lncRNAs showed that they were enriched in pathways related to viral infection and immune response, indicating that lncRNAs might play regulatory roles in virus-host interactions. Our study provided information about lncRNAs in the porcine immune system and offers new insights into the pathogenic mechanism of PRRSV infection and novel antiviral therapy development.

Abstract
Bluetongue virus (BTV) causes a non‐contagious, arthropod‐transmitted disease in wild and domestic ruminants, such as sheep. In this study, we used iTRAQ labeling coupled with LC‐MS/MS for quantitative identification of differentially expressed proteins in BTV‐infected sheep testicular (ST) cells. Relative quantitative data were obtained for 4455 proteins in BTV‐ and mock‐infected ST cells, among which 101 and 479 proteins were differentially expressed at 24 and 48 h post‐infection, respectively, indicating further proteomic changes during the later stages of infection. Ten corresponding genes of differentially expressed proteins were validated via real‐time RT‐PCR. Expression levels of three representative proteins, eIF4a1, STAT1 and HSP27, were further confirmed via western blot analysis. Bioinformatics analysis disclosed that the differentially expressed proteins are primarily involved in biological processes related to innate immune response, signal transduction, nucleocytoplasmic transport, transcription and apoptosis. Several upregulated proteins were associated with the RIG‐I‐like receptor signaling pathway and endocytosis. To our knowledge, this study represents the first attempt to investigate proteome‐wide dysregulation in BTV‐infected cells with the aid of quantitative proteomics. Our collective results not only enhance understanding of the host response to BTV infection but also highlight multiple potential targets for the development of antiviral agents.
