The mRNA and microRNA (miR) transcriptome of lung neutrophils during S. pneumoniae (SP) pneumonia in wild type (WT) mice [miRNA]

ABSTRACT: These studies profiled the expression of mRNAs and microRNAs (miRs) in lung neutrophils in WT mice during S. pneumoniae pneumonia and performed in depth in silico analyses. Lung neutrophils were isolated 24 hours after intratracheal instillation of PBS or S. pneumoniae, and mRNAs and miRs differentially expressed (DE) between S. pneumoniae- and PBS-treated samples were identified using microarrays.

Host response to S. pneumoniae TIGR4 and ΔpotABCD

Project description:The aim of this experiment is to determine the difference in protein expression, if any, in a mouse model of pneumococcal pneumonia using wild type and a polyamine transport operon deletion mutant strain of S. pneumoniae TIGR4, using expression proteomics. Eight week old female C57bl/6 mice were used in this study. The experimental design had two groups of 3 animals each that were administered 50 µL 1 X 107 CFU wild type S. pneumoniae TIGR4 or S. pneumoniae TIGR4 ΔpotABCD strain by intranasal instillation. The control group with three animals received 50 µL PBS. Mice were euthanized 4 hr and 12 hr post infection and lung tissues were harvested. The control group animals were euthanized 12 hr post infection.

Leukocyte kinetics and bacterial clearance during S. pneumoniae pneumonia and contributions of ICAM-1

Project description:Streptococcus pneumoniae is a leading cause of community-acquired pneumonia. Intercellular adhesion molecule-1 (ICAM-1) is an adhesion molecule that is highly expressed on the pulmonary capillary endothelium, alveolar epithelium and other cell types within the lung. ICAM-1 is known to play important roles in leukocyte adhesion, migration, and motility. To determine the contributions of ICAM-1 to bacterial clearance and leukocyte kinetics during pneumonia, mice were inoculated with S. pneumoniae and evaluated 1, 4 and 7 days later. Our results show that Icam1-/- mice have a greater number of viable bacteria within the lung at each time point. The impaired clearance observed in Icam1-/- mice was not due to an impediment in leukocyte recruitment. In fact, Icam1-/- mice had a greater number of neutrophils and recruited inflammatory macrophages in the lung tissue and the alveoli/airways on day 7. In contrast, fewer alveolar macrophages were present in the BAL of Icam1-/- mice. The loss of body weight and the concentrations of inflammatory mediators in the BAL were also significantly greater in Icam1-/- mice. Mechanistic studies to understand the defect in clearance show that neutrophils and macrophage subpopulations had no defect in phagocytosis or acidification of phagosomes. RNA sequencing reveals many differences in gene expression, but does not suggest° a defect in phagocytosis. Thus, ICAM-1 is necessary for the clearance of S. pneumoniae and for the resolution of pneumonia, but is not required for the recruitment of neutrophils or inflammatory macrophages into the pneumonic lung parenchyma or the alveoli/airways during S. pneumoniae-induced pneumonia.

Myeloid PDLIM2 repression as a common causal mechanism of lung disease pathogenesis and susceptibility to infection

Project description:Selective deletion of PDLIM2 in myeloid cells rendered mice more vulnerable to lung injury and mortality after LPS intratracheal instillation, which was associated with the exacerbated activation of pro-inflammation signaling pathways and the more diminished activation of anti-inflammation signaling pathways in the lung, and particularly, in lung macrophages and neutrophils.

Gene expression profiling of neutrophils and whole lung tissue from wildtype and Nrf2 null (Nfe2l2-/-) mice during S. pneumoniae pneumonia [neutrophils]

Project description:The transcription factor Nrf2 (gene symbol Nfe2l2) regulates the transcriptional response to oxidative stress and plays a critical protective role in the lungs. These studies tested the role of Nrf2 during pneumonia induced by Streptococcus pneumoniae (SP) at 24 hours in mice and identified Nrf2-dependent genes and pathways in lung tissue and in recruited neutrophils.

Transcriptional Analysis of Foxp3+ Regulatory T Cells in Experimental Acute Lung Injury Resolution

Project description:These studies profiled the expression of mRNA in lung and spleen regulatory T cells in Foxp3EGFP mice during lipopolysaccharide-induced lung injury. Baseline, uninjured Lung Treg and Resolving Lung Tregs and Resolving Splenic Tregs were sorted (7 days after intratracheal instillation of LPS for Resolving conditions) and mRNAs differentially expressed (DE) between Control Lung Tregs, Resolving Lung Tregs and Resolving Splenic Tregs samples were identified using microarrays.

Hepatic induction of cholesterol biosynthesis reflects a remote adaptive response to pneumococcal pneumonia

Project description:Transcriptional effects in liver, lung and blood samples from mice after intratracheal challenge with either Streptococcus pneumoniae serotype 19 (lobar-pneumonia) or serotype 2 (sepsis) were monitored after 6 and 24 hours and compared to sham (vehicle control). We gratefully acknowledge the BMBF grant within the “Promoting global research excellence in severe sepsis” (PROGRESS) study (01KI07111).
