Protein-coding and non-coding RNA expression in whole blood leukocytes during experimental human endotoxemia.

Project description:Genome-wide gene expression profiling of whole blood leukocytes during experimental human endotoxemia has been used extensively to model acute systemic host responses. Through technological advances in genomics it has become clear that transcription is not limited to protein-coding regions of the genome. Here, we describe a comprehensive analysis of RNA expression of blood leukocytes in healthy volunteers during experimental human endotoxemia.

Small non-coding RNA expression in whole blood leukocytes of healthy subjects, critically-ill patients with sepsis or non-infectious etiology and human endotoxemia

Project description:Genome-wide gene expression profiling of whole blood leukocytes in critically ill patients with sepsis or non-infectious disease has been used extensively in search of diagnostic biomarkers, as well as prognostic signatures reflecting diseases severity and outcome. Through technological advances in genomics it has become clear that transcription is not limited to protein-coding regions of the genome. Here, we describe a comprehensive analysis of small non-coding RNA expression in blood leukocytes of critically ill patients with sepsis, a non-infectious condition, healthy subjects and experimental human endotoxemia

Transcriptome kinetics of circulating neutrophils during human experimental endotoxemia

Project description:Polymorphonuclear cells (neutrophils) play an important role in the systemic inflammatory response syndrome and the development of sepsis. These cells are essential for the defense against microorganisms, but may also cause tissue damage. Therefore, neutrophil numbers and activity are considered to be tightly regulated. Previous studies have investigated gene transcription during experimental endotoxemia in whole blood and peripheral blood mononuclear cells. However, the gene transcription response of the circulating pool of neutrophils to systemic inflammatory stimulation in vivo is currently unclear. We examined neutrophil gene transcription kinetics in healthy human subjects (n=4) administered a single dose of endotoxin (LPS, 2 ng/kg iv). In addition, freshly isolated neutrophils were stimulated ex vivo with LPS, TNFα, G-CSF and GM-CSF to identify stimulus-specific gene transcription responses. Whole transcriptome microarray analysis of circulating neutrophils at 2, 4 and 6 hours after LPS infusion revealed activation of inflammatory networks which are involved in signaling of TNFα and IL-1α and IL-1β. The transcriptome profile of inflammatory activated neutrophils in vivo reflects extended survival and regulation of inflammatory responses. We show that these changes in neutrophil transcriptome are most likely due to a combination of early activation of circulating neutrophils by TNFα and G-CSF and a mobilization of young neutrophils from the bone marrow.

In addition, freshly isolated neutrophils were stimulated ex vivo with LPS, TNFM-NM-1, G-CSF and GM-CSF to identify stimulus-specific gene transcription responses. Whole transcriptome microarray analysis of circulating neutrophils at 2, 4 and 6 hours after LPS infusion revealed activation of inflammatory networks which are involved in signaling of TNFM-NM-1 and IL-1M-NM-1 and IL-1M-NM-2. The transcriptome profile of inflammatory activated neutrophils in vivo reflects extended survival and regulation of inflammatory responses. We show that these changes in neutrophil transcriptome are most likely due to a combination of early activation of circulating neutrophils by TNFM-NM-1 and G-CSF and a mobilization of young neutrophils from the bone marrow. After LPS infusion blood was taken at t=0, t=2, t=4 and t=6 hours. Neutrophils were isolated and gene expression of these cells was assessed. T=2, t=4 and t=6 were related to t=0 as control condition

Single-cell RNA sequencing of liver nonparenchymal cells from murine model of endotoxemia

Project description:Liver has a crucial role in the regulation of immune defense in systemic infections. During endotoxemia, the liver transits from an immune-tolerant towards an immune-active state and forms the first line of defense against invading microorganisms. the role of liver nonparenchymal cells in endotoxemia remains unintelligible. To characterize the liver nonparenchymal cells in endotoxemia liver, we performed single-cell RNA sequencing of liver nonparenchymal cells from healthy C57BL/6J mice and murine model of endotoxemia at early or late stage. The single-cell RNA-seq analyses revealed the heterogeneity of liver nonparenchymal cells in endotoxemia liver.
