Host transcriptome analysis of Aspergillus fumigatus infection in Airway Epithelial Cells

ABSTRACT: The goal of this study is to determine the transcriptional response of primary normal human bronchial epithelial (NHBE) cells following interaction with A. fumigatus conidia at 2, 6, and 12 hours in order to examine the infection of airway epithelial cells at multiple time points of co-incubation. After total RNA isolation, the Illumina® HiSeq 2000 next generation sequencing system was used to characterize the transcriptional response, in untreated and A. fumigatus exposed cells.

RNA-Seq analysis of gene expression changes by wildtype and Nlrx1 deficient BEAS-2B airway epithelial cells in response to A. fumigatus viable conidia

Project description:Aspergillus fumigatus is an opportunistic fungal pathogen of the respiratory system that may cause invasive infection or an allergic response. Bronchial airway epithelial cells compromise the most abundant cell type of the pulmonary-air interface. Our recent findings suggest loss of Nlrx1 by BEAS-2B airway epithelial cells result in a hyper inflammatory response as well as decreased conidial processing. We challenged wildtype Nlrx1 deficient BEAS-2B cells with viable A. fumigatus AF293 conidia to identify early response differentially expressed genes and pathways between the two cell populations.

Next Generation Sequencing of HUVECs stimulated by conidia of Aspergillus fumigatus

Project description:Purpose: The goal of this study is to investigate the responses of HUVECs after the stimulation of conidia of A. fumigatus Methods: HUVECs were stimulated with conidia of Aspergillus fumigatus for 2 and 6 hours. Three biological repeats of stimulated cells or un-stimulated controls were send for RNA sequencing. Results: Using an optimized data analysis workflow, we mapped about 40 million sequence reads per sample to the human genome (build hg38) and identified round 80,000 transcripts in the HUVECs upon stimulation. Conclusions: Our resutls showed the detailed analysis of HUVECs transcriptomes upton conidia of Aspergillus fumigatus stimulation.

Cells were grone for various times and comparisons made between: 1. Dormant conidia (0 hours) and isotropically expanding cells (1hr). 2. Dormant conidia (0 hours) and isotropically expanding cells (2hr) . 3. Dormant conidia (0 hours) and isotropically expanding cells (4hr). 4. Isotropically expanding cells (4hr) and polarity extending cells (6hr). 4. Isotropically expanding cells (4hr) and germ tube (8hr).

Response of A549 cells treated with Aspergillus fumigatus [WT-GC_vs_PrtT-GC]

Project description:Response of A549 cells treated with Aspergillus fumigatus wild type germinating conidia (WT_GC) or PrtT protease deficient mutant conidia (PrtT-GC) or inert acrylic 2-4 micron beads (Beads) for 8h Aspergillus fumigatus is the most commonly encountered mold pathogen of humans, predominantly infecting the respiratory system. Colonization and penetration of the lung alveolar epithelium is a key but poorly understood step in the infection process. This study focused on identifying the transcriptional and cell-signaling responses activated in A549 alveolar carcinoma cells incubated in the presence of A. fumigatus wild-type and ÎPrtT protease-deficient germinating conidia and culture filtrates (CF). Microarray analysis of exposed A549 cells identified distinct classes of genes whose expression is altered in the presence of germinating conidia and CF and suggested the involvement of both NFkB and MAPK signaling pathways in mediating the cellular response. Phosphoprotein analysis of A549 cells confirmed that JNK and ERK1/2 are phosphorylated in response to CF treatment in a protease-dependent manner. Inhibition of JNK or ERK1/2 kinase activity substantially decreased CF-induced cell damage, including cell peeling, actin-cytoskeleton damage, and reduction in metabolic activity and necrotic death. These results suggest that inhibition of MAPK-mediated host responses to treatment with A. fumigatus CF decreases cellular damage, a finding with possible clinical implications. 2 independent controls (uninfected A549 cells) as ctrl3_1-2, 2 independent treatments of A549 cells with wild-type A. fumigatus germinating conidia (WT_GC_1-2 ) , 2 independent treatments of A549 cells with inert acrylic beads (Beads 1-2), 3 independent treatments of A549 cells with A. fumigatus prtT mutant germinating conidia (PrtT-GC_1-3).

Aspergillus fumigatus whole genome transcriptomic study using AWAFUGE microarray after exposition to murine macrophages (RAW 264.7) and human lung epithelial cells (A549).

Project description:Aspergillus fumigatus is a filamentous fungus capable to cause an important disease known as invasive aspergillosis. Challenge different cell lines is a crucial strategy to undercover new virulence factors involved in the infection process. In this research, RAW 264.7 macrophages and A549 lung epithelial cells were challenge using A. fumigatus conidia in a MOI of 10 and 5 respectively. When these conidia reach 30% of germination, the total RNA was isolated (A. fumigatus alone (Control), A. fumigatus vs RAW 264.7, and A. fumigatus vs A549) and purified using the RNeasy Plant Mini Kit (Qiagen). The AWAFUGE (Agilent Whole A. fumigatus Genome Expression 44K v.1) hybridization was carried out following previously publish protocols (A-MEXP-2352 and E-MTAB-5314).

Human monocyte-derived macrophage response to Aspergillus fumigatus

Project description:To investigate the influence of Aspergillus fumigatus on iron regulation in macrophages, we obtained macrophages in culture from human derived monocytes and co-cultured the monocyte-derived macrophages with Aspergillus conidia at a 1:1 ratio. We collected samples at 0, 2, 4, 6 and 8 hours and extracted RNA. We then performed gene expression profiling analysis using data obtained from RNA-seq of control macrophages and macrophage co-cultured with Aspergillus fumigatus at five time points.
