Human monocyte-derived macrophage response to Aspergillus fumigatus
Ontology highlight
ABSTRACT: 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.
Project description:Aspergillus fumigatus is an important human pathogen and a leading fungal killer. This study aimed to determine the small RNA repertoire of A. fumigatus in conidia and mycelium grown for 24 or 48 hours in liquid culture.
Project description:Aspergillus fumigatus is an important human pathogen and a leading fungal killer. This study aimed to determine the tRNA fragment and tRNA half repertoire of A. fumigatus in wild-type conidia and mycelium grown for 24 or 48 hours in liquid culture.
Project description:We sequenced total RNA from human monocyte derived macrophages (n = 6, healthy donors) pre-treated with calcineurin inhibitor FK506 (10 ng/ml) for 1h and stimulated with live Aspergillus fumigatus swollen conidia (MOI=1) for 1h and 6h.
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.
Project description:Genomic DNA from five strains, Aspergillus fumigatus Af71, Aspergillus fumigatus Af294, Aspergillus clavatus, Neosartorya fenneliae, and Neosartorya fischeri, were co-hybridized with that of Aspergillus fumigatus Af293 and compared.
Project description:We report the gene expression level of Aspergillus fumigatus CEA17_ΔakuBKU80 strain in dormant conidia, in swollen conidia (after 4h of culture in Glucose 3%, Yeast Exrtract 1% liquid medium) and in germinated conidia (after 8h of culture in Glucose 3%, Yeast Extract 1% liquid medium after construction of an RNAseq library.
Project description:The study investigated the interaction between pentraxin-3 (PTX3), a soluble pattern-recognition receptor, and the fungal pathogen Aspergillus fumigatus. The aim was to identify the ligands for PTX3 and the impact of PTX3 on the immune response. A. fumigatus spores, hyphae or cell wall components were incubated with PTX3, human serum and others humoral factors and their interaction was studied by immunofluorescence, flow cytometry and ELISA. Opsonizd conidia were co-incubated with human monocyte-derived macrophages (hMDM) and cytokine secretion was measured.
Project description:Microarray analysis was used to compare different divelopmental stages of the filamentous fungi Aspergillus fumigatus af293. 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).
Project description:Dendritic cells (DC) are the most important antigen presenting cells and play a pivotal role in host immunity to infectious agents by acting as a bridge between the innate and adaptive immune systems. Myeloid DCs (mDC) were isolated from peripheral blood and co-cultured with conidia (con) and germlings (ks) of Aspergillus fumigatus knockout (mitA, mnt1, rodA) and wildtype (wt) strains for 6 hours at an MOI of 1. RNA was extracted and hybridised to microarrays. Microarrays contain probes for approximately 110 selected human immune-relevant genes, including cytokine and chemokine genes, their receptors and downstream innate immunity genes. We used microarrays to detail the gene expression of human myeloid dendritic cells after 6h of co-cultivation with Aspergillus fumigatus wildtype and knockout mutants
