Gene expression profiling of bronchoalveolar lavage cells during Aspergillus colonization of the lung allograft

ABSTRACT: Background: Aspergillus colonization after lung transplant is associated with an increased risk of chronic lung allograft dysfunction (CLAD). We hypothesized that gene expression during Aspergillus colonization could provide clues to CLAD pathogenesis. Methods: We examined transcriptional profiles in 3 or 6-month surveillance bronchoalveolar lavage fluid cell pellets from recipients with A. fumigatus colonization (n=12) and without colonization (n=10). Among the Aspergillus colonized, we also explored profiles in those who developed CLAD (n=6) or remained CLAD free (n=6). Transcription profiles were assayed with the HG-U133 Plus 2.0 microarray (Affymetrix). Statistical Analysis: Differential gene expression analyses were performed to select candidate lists of genes. Functional analyses on these selected genes were explored.

Gene expression profiling of bronchoalveolar lavage cells preceding a clinical diagnosis of chronic lung allograft dysfunction

Project description:Chronic Lung Allograft Dysfunction (CLAD) is the main limitation to long-term survival after lung transplantation. Although CLAD is usually not responsive to treatment, earlier identification may improve treatment prospects. In a nested case control study, 1-year post transplant surveillance bronchoalveolar lavage (BAL) fluid samples were obtained from incipient CLAD (n=9) and CLAD free (n=8) lung transplant recipients. Incipient CLAD cases were diagnosed with CLAD within 2 years, while controls were free from CLAD for at least 4 years following bronchoscopy. Transcription profiles in the BAL cell pellets were assayed with the HG-U133 Plus 2.0 microarray (Affymetrix). Differential gene expression analysis was performed to identify a candidate list of differentially expressed probe sets.

Transcriptional profiling of ATCC46645 strain and isogenic M-NM-^TpacC Aspergillus fumigatus mutant during murine infection

Project description:In lung diseases caused by the major mould pathogen Aspergillus fumigatus the pulmonary epithelium is destroyed by invasive growth of fungal hyphae, a process thought to require fungal proteases. Here we show that the A. fumigatus pH-responsive transcription factor PacC governs expression of secreted proteases during invasive lung infections and is required for epithelial invasion and pathogenicity. In addition, A. fumigatus M-NM-^TpacC mutants aberrantly remodel the fungal cell wall during infection. This study defines distinct PacC-mediated mechanisms of host damage during pulmonary aspergillosis. ch1: treatment protocol Temporal transcriptional profiling of ATCC46645 strain and isogenic M-NM-^TpacC Aspergillus fumigatus mutant during murine infection

RNA-seq analysis of wildtype Aspergillus fumigatus A1160p+, ∆devR and ∆acdX in the presence and absence of Olorofim

Project description:Deletion of transcription factors DevR and AcdX in Aspergillus fumigatus causes increased/decreased susceptibility to the antifungal Olorofim. In order to characterise the basis of differential Olorofim susceptibility, and distinguish which metabolic pathways these transcription factors regulate, RNA-seq analysis was used to compare these transcription factor knockout mutants to wildtype A. fumigatus in both the presence and absense of Olorofim.

Transcription profiling of human bronchoalveolar lavage samples collected from lung transplant recipients with rejection states determined at the time of sample collection

Project description:Bronchoalveolar lavage samples collected from lung transplant recipients. Numeric portion of sample name is an arbitrary patient ID and AxBx number indicates the perivascular (A) and bronchiolar (B) scores from biopsies collected on the same day as the BAL fluid was collected. Several patients have more than one sample in this series and can be determined by patient number followed by a lower case letter. Acute rejection state is determined by the combined A and B score - specifically, a combined AB score of 2 or greater is considered an acute rejection.

Transcriptional profile of M-NM-^TcalA and M-NM-^TcrzA Aspergillus fumigatus mutants during mammal infection

Project description:Aspergillus fumigatus mutant strains were collected from bronchoalveolar lavage fluids (BALFs) during acute mouse infection (4 and 12 hours). Transcriptional analysis were conducted by comparison of each mutant with the wild type strain (CEA17) in a dye swap experiment. Besides, we performed the transcriptional profile of akuB(KU80) mutant compared to CEA17 wild type strain. All the strains were recovered from bronchoalveolar lavage fluid from CD1 mice infected with 10e8 spores for 4 and 12 hours.

Functional genomics of Aspergillus fumigatus conidiospores interacting with human bronchial epithelial cells

Project description:The cells of the airway epithelium play critical roles in host defense to inhaled irritants, and in asthma pathogenesis. These cells are constantly exposed to conidiospores of the ubiquitous mould Aspergillus fumigatus, which are small enough to reach the alveoli. This exposure is asymptomatic in most individuals but can be associated with a spectrum of diseases ranging from asthma and allergic bronchopulmonary aspergillosis to aspergilloma and invasive aspergillosis. Airway epithelial cells have been shown to internalize A. fumigatus conidiospores in vitro, but the implications of this process for pathogenesis remain unclear. We have developed a cell culture model for this interaction using the 16HBE cell line and a transgenic A. fumigatus strain expressing green fluorescent protein. The transcriptional profiles of A. fumigatus conidiospores incubated in the presence or absence of human cells were compared, revealing significant changes in fungal gene expression in response to conidial interaction with cells. Gene expression levels were investigated in A. fumigatus conidiospores incubated in the presence or absence of 16HBE cells for 6 hours. Four independent samples were analysed for each of these conditions, using JCVI PFGRC Aspergillus fumigatus Version 3 microarrays, with a dye-swap experimental design.
