Uninfected and human respiratory syncytial virus (RSV)-infected A549 cells, analysed using bottom-up mass spectrometry

Project description:Proteomic data from uninfected and human respiratory syncytial virus (RSV) infected A549 cells (24h post infection; four biological replicate sets). Data is related to the fractionation-free workflow described in Dave et al. (2014) (PMID: 25106423). Data is processed using MaxQuant (version 1.3.0.5).

Multiple RSV strains infecting HEp-2 and A549 cells reveal cell line-dependent differences in resistance to RSV infection

Project description:A few transformed cell lines and two historic strains have been extensively used to study respiratory syncytial virus (RSV). We report a thorough molecular and cell biological characterization of HEp-2 and A549 cells infected with four strains of RSV representing both major subgroups as well as historic and more contemporary genotypes -- [RSV/A/Tracy (GA1), RSV/A/Ontario (ON), RSV/B/18537 (GB1), RSV/B/Buenos Aires (BA)] -- via measurements of viral replication kinetics and viral gene expression, immunofluorescence-based imaging of gross cellular morphology and cell-associated RSV, and measurements of host response including transcriptional changes and levels of secreted cytokines and growth factors. Our findings strongly suggest 1) the existence of a conserved difference in gene expression between RSV subgroups A and B; 2) the A549 cell line is a more stringent and natural host of replicating RSV than the HEp-2 cell line; and 3) consistent with previous studies, determining the full effects of viral genetic variation in RSV pathogenesis requires model systems as tractable as transformed cell lines but better representative of the human host.

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.

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.

Respiratory Syncytial Virus (RSV) optimizes the translational landscape during infection

Project description:Viral infection often triggers eukaryotic initiator factor 2α (eIF2α) phosphorylation, leading to global 5’-cap-dependent translation inhibition. RSV encodes messenger RNAs (mRNAs) mimicking 5’-cap structures of host mRNAs and thus inhibition of cap-dependent translation initiation would likely also reduce viral translation. We confirmed that RSV limits widespread translation initiation inhibition and unexpectedly found that the fraction of ribosomes within polysomes increases during infection, indicating higher ribosome loading on mRNAs during infection. We found that AU-rich host transcripts that are less efficiently translated under normal conditions become more efficient at recruiting ribosomes, similar to RSV transcripts. Viral transcripts are transcribed in cytoplasmic inclusion bodies, where the viral AU-rich binding protein M2-1 has been shown to bind viral transcripts and shuttle them into the cytoplasm. We further demonstrated that M2-1 is found on polysomes, and that M2-1 might deliver host AU-rich transcripts for translation.
