Bronchial epithelial cells transcriptomics upon flagellin stimulation (Microarray)

Project description:Innate immune memory is a new concept describing ability of innate myeloid and lymphoid cells to gain memory characteristics after transient stimulation, resulting in an nonspecific modified response upon secondary challenge. In recent work, we demonstrated that bronchial epithelial cells, non immune cells, that are the first immune cells of the lower respiratory tract to encounter pathogens were capable of innate immune memory after pre-exposure to Pseudomonas aeruginosa flagellin. In the present study we identified chromatin modifications induced by flagellin pre-exposure that sustain reprogramming of transcriptional patterns. We researched chromatin structure modifications responsible for the modulation of gene expression and thus of innate memory induced by the exposure of cells to flagellin.

Single-cell transcriptomics reveals subset-specific metabolic profiles underpinning the bronchial epithelial response to flagellin

Project description:Airway epithelial cells represent the first line of defense against respiratory pathogens. Flagellin drives the motility of many mucosal pathogens and has been suggested as an immune enhancing adjunctive therapeutic in infections of the airways. This study leveraged single-cell RNA sequencing to determine cell-specific effects of flagellin in primary human bronchial epithelial cells growing in air-liquid interface. Seven cell clusters were identified, including ciliated cells, ionocytes and several states of basal and secretory cells, of which only inflammatory basal cells and inflammatory secretory cells demonstrated a proportional increase in response to flagellin. Inflammatory secretory cells showed evidence of metabolic reprogramming toward aerobic glycolysis, whilst in inflammatory basal cells transcriptome profiles indicated enhanced oxidative phosphorylation. Inhibition of mTOR prevented the shift to glycolysis and reduced inflammatory gene transcription specifically in inflammatory secretory cells. This data demonstrates the functional heterogeneity of the human airway epithelium upon exposure to flagellin.

Hypoxic response for human bronchial epithelial culture [bulkRNA-Seq batch1]

Project description:Purpose: To identify the gene expression change under hypoxia on HBE cells. Methods: bulk RNA-seq was performed on primary human bronchial epithelial cells (HBE) that were cultured on air-liquid interface (ALI) condition and treated under normoxia or hypoxia (1% O2) for 6hr, 24hr, and 5days. Results: hypoxia-related genes were significantly upregulated under hypoxia including EGLN3.

Chronic hypoxic response for human bronchial epithelial culture [bulkRNA-Seq batch2]

Project description:Purpose: To identify the gene expression change under chronic hypoxia on HBE cells. Methods: bulk RNA-seq was performed on primary human bronchial epithelial cells (HBE) that were cultured on air-liquid interface (ALI) condition and treated under normoxia or hypoxia (1% O2) for 5days. Results: inflammatory cytokines, collagen degradation, and angiogenic genes were upregulated under chronic hypoxia.
