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.

Project description:In airway epithelial cells, Tlr4 mediates both innate and adaptive immune responses to viral pathogens through the surface fusion glycoprotein (RSV F), however the mechanism is not well characterized. We used microarrays to identify Tlr4-mediated gene expression pathways induced by RSV infection.

Project description:Lower respiratory tract infections (LRTI) from human Respiratory Syncytial Virus (RSV) are a significant cause of morbidity in children. A component of LRTI pathogenesis is due to signals generated by infected lower airway cells that alter lymphocyte populations and trigger airway remodeling. To obtain insights into this process, we applied an unbiased quantitative proteomics analysis of the RSV-induced epithelial secretory response in cells representative of the trachea (hBECs) vs small airway bronchiolar cells (hSAECs). A workflow was standardized initially using telomerase immortalized human epithelial cells that showed high reproducibility and cell-type differences in proteomic signatures of both secreted proteins and isolated nanoparticles (exosomes). Over half of secretome proteins were contained within exosomal, with the remainder originating from lysosomal and vaculolar compartments. We applied this workflow to three independently derived primary human cultures. 577 differentially expressed proteins from control supernatants and 966 differentially expressed proteins from RSV-infected cell supernatants were identified at a 1% false discovery rate (FDR). 15 proteins were unique to RSV-infected hBECs regulated by epithelial-specific ets homology factor (EHF). 106 proteins were unique to RSV-infected hSAECs enriched in proteins regulated by the NFB transcription factor. In this latter group, we independently validated the differential expression of Chemokine (C-C Motif) Ligand 20 (CCL20)/macrophage inducible protein (MIP)3, Thymic Stromal Lymphopoietin (TSLP) and chemokine (CC) ligand 3-like 1(CCL3-L1). CCL20/MIP3 is the most active mucin inducing factor in the RSV infected hSAEC secretome, and is differentially expressed in smaller airways in a mouse model of RSV infection. These studies provide insight into role of exosomal production in innate responses and regional differences in epithelial secretomes that participate in pathogenesis of RSV LRTI-induced airway remodeling.

Project description:We studied RSV infection in an appropriate in vitro model of respiratory epithelium, a pseudostratified and fully differentiated mucociliary epithelium of normal human bronchial epithelial (NHBE) cells. RSV infection increased actin cytoskeleton without compromising adherent-, tight-, and tricellular-junctions as well as ciliary functions and epithelial tissue barrier integrity. This increased cytoskeleton depends on actin polymerization and the induction of proinflammatory cytokines and chemokines. Thus, we observed a novel signature “increased cytoskeleton” termed “cytoskeletal inflammation” in RSV-infected respiratory epithelium that presumably lacks classical antigen presenting cells, such as resident dendritic cells and macrophages. Our results suggest that RSV-induced cytoskeletal inflammation is a noncanonical earliest host response to the pathogen and contributes to airway inflammation.
