Comprehensive Analysis of Ubiquitome Changes in <i>Nicotiana benthamiana</i> after Rice Stripe Virus Infection.

Liu Yu Y Li Chenyang C Wang Yaqin Y Xu Yi Y Wu Jianxiang J Zhou Xueping X

Viruses 20221026 11

Rice stripe virus (RSV) is one of the most devastating viruses affecting rice production. During virus infection, ubiquitination plays an important role in the dynamic regulation of host defenses. We combined the ubiquitomics approach with the label-free quantitation proteomics approach to investigate potential ubiquitination status changes of <i>Nicotiana benthamiana</i> infected with RSV. Bioinformatics analyses were performed to elucidate potential associations between proteins with different ...[more]

RSV vs BSA

Project description:Rationale: Respiratory syncytial virus (RSV) and Streptococcus pneumoniae are major respiratory pathogens. Co-infection with RSV and S. pneumoniae is associated with severe and often fatal pneumonia but the molecular basis for this remains unclear. Objectives: To determine if interaction between RSV and pneumococci enhances pneumococcal virulence. Methods: We used confocal microscopy and western blot to identify the receptors involved in direct binding of RSV and pneumococci, the effects of which were studied in both in vivo and in vitro models of infection. Human ciliated respiratory epithelial cell cultures were infected with RSV for 72h and then challenged with pneumococci. Pneumococci were collected after 2h exposure and changes in gene expression determined using qRT-PCR. Results: Following incubation with RSV or purified G protein, pneumococci demonstrated a significant increase in the inflammatory response and bacterial adherence to human ciliated epithelial cultures and markedly increased virulence in a pneumonia model in mice. This was associated with extensive changes in the pneumococcal transcriptome and significant upregulation in the expression of key pneumococcal virulence genes, including the gene for the pneumococcal toxin, pneumolysin. We show that mechanistically this is due to RSV G glycoprotein binding penicillin binding protein 1a. Conclusion: The direct interaction between a respiratory virus protein and the pneumococcus resulting in increased bacterial virulence and worsening disease outcome is a new paradigm in respiratory infection.

An Unexpected Encounter: Respiratory Syncytial Virus Non-Structural Protein 1 Interacts With Mediator Subunit MED25

Project description:Human respiratory syncytial virus (RSV) is the leading cause of severe acute lower respiratory tract infections in infants worldwide. Non-structural protein NS1 of RSV modulates the host innate immune response by acting as an antagonist of type I and type III interferon (IFN) production and signaling in multiple ways. It is likely that NS1 performs this function by interacting with different host proteins. In order to obtain a comprehensive overview of NS1 interaction partners, we performed three complementary protein-protein interaction screens i.e. BioID, MAPPIT and KISS. The BioID proximity screen was performed during an RSV infection in A549 cells. MED25, a subunit of the Mediator complex, was identified in all 3 performed screening methods as a potential NS1 interacting protein. We confirmed the interaction between MED25 and RSV NS1 by co-immunoprecipitation, not only upon overexpression of NS1, but also with endogenous NS1 during RSV infection. We also demonstrate that the replication of RSV is enhanced in MED25 knockout A549 cells, suggesting a potential antiviral role of MED25 during RSV infection. Mediator subunits function as transcriptional coactivators and are involved in transcriptional regulation of their target genes. Therefore, the interaction between RSV NS1 and cellular MED25 might be beneficial during an RSV infection as this can affect host transcription and the host immune response to infection.

The response of human primary airway epithelial cells to Influenza or RSV infection [hAECs_Agilent].

Project description:To investigate how human airway epithelial cells respond to Influenza or RSV infection, we harvested airway epithelial cells from the mainstream bronchi of human donors and cultured them as previously described (Pickles et al,1998) in a polarized system that resembles the in vivo mucociliary pseudostratified epithelium. Quadruplicate hAEC cultures were infected with 2X105 PFUs Influenza A (Udorn) or with 1x106 PFUs RSV for 2h or mock inoculated and harvested 24h after Influenza infection and 48h after RSV infection. Quadruplicate polarized airway epithelial cell cultures were mock treated or infected with 2x10^5 PFUs of Influenza A (Udorn) for 2h or infected with 1x10^6 PFUs RSV and harvested 24 h post infection for Influenza or 48h post infection for RSV. Total RNA was harvested and gene expression was studied using Genespring GX v7.3.1.

DC response to Respiratory syncytial virus from adult peripheral and cord blood

Project description:Respiratory syncytial virus (RSV) is a major cause of morbidity and mortality. Previous studies have suggested that T cell responses may contribute to RSV immunopathology, which could be driven by dendritic cells (DCs). DCs are productively infected by RSV, and during RSV infections, there is an increase of DCs in the lungs with a decrease in the blood. Pediatric populations are particularly susceptible to severe RSV infections, however DC responses to RSV from pediatric populations have not been examined. In this study, primary isolated DCs from cord blood and adult peripheral blood were compared after RSV-infection. Transcriptional profiling and biological network analysis identified transforming growth factor (TGF)-b and associated signaling molecules as differentially regulated in the two age groups. TGF-b1 was decreased in RSV-infected adult blood DCs, but increased in RSV-infected cord blood DCs. Co-culture of adult RSV-infected DCs with autologous T-cells induced secretion of interferon gamma (IFNg), IL-12p70, IL-2, and tumor necrosis factor alpha (TNFa). Conversely, co-culture of cord RSV-infected DCs and autologous T-cells induced secretion of IL-4, IL-6, IL-1b, and IL-17. Addition of purified TGF-b1 to adult DC-T cell co-cultures reduced secretion of IFNg, IL-12p70, IL-2, and TNFa, which addition of a TGF-b chemical inhibitor to cord DC-T cell co-cultures increased secretion of IL-12p70. These data suggest that TGF-b acts as a major regulator of RSV DC-T cell responses, which could contribute to immunopathology during infancy. Three sets of adult peripheral DCs were analyzed and three sets of cord blood DCs. The DCs from each donor were divided in half and either mock infected or infected with RSV and each (12 samples total) were used for affymetrix array analsis. The donor-matched mock infected DC hybridyzation was used as the reference sample for the RSV infected.

Proteomic analysis of Laodelphax striatellus in response to rice stripe virus infection

Project description:Persistent plant viruses multiply and circulate inside insect vectors following the route of midgut-hemolymph-salivary gland. Currently, how viruses interact with insect vectors after they are released into hemolymph is not entirely clear. In this study, we found that the hemolymph and fat body (HF) contained the highest RSV levels. Proteomic analysis on RSV-free and RSV-infected HF identified 156 differentially expressed proteins (DEPs), with the majority of them participating in metabolism, transportation, and detoxification.
