Project description:To determine whether differential expression of cellular microRNAs plays a role in the host response to Influenza A (H1N1) infection, we have employed the Agilent miRNA microarray (V3) as a discovery platform to identify microRNAs between the critically ill Patients with Influenza A (H1N1) and the healthy controls. Five critically ill patients with a diagnosis of 2009 Inflluenza A (H1N1) and three healthy controls were included in the study. The Peripheral Blood Mononuclear Cells (PBMCs) were isolated and total RNA was extracted respectively.
Project description:Longitudinal Gene expression profiling of whole blood from critically ill influenza and bacterial pneumonia patients. In addition before vs 7 days post influenza vaccination volunteer samples are assayed.
Project description:Critically ill infants and children with suspected monogenic conditions underwent ultra-rapid whole exome genetic testing. A molecular diagnosis was established in 51% of the patients. This study suggests feasibility of ultra-rapid genomic testing in critically ill pediatric patients.
Project description:The number of organ failures at intensive care unit (ICU) admission is the main prognostic factor in septic shock. The aim was to assess classical clinico-biological parameters evaluating organ dysfunctions at ICU admission, combined with proteomics analysis, on day-30 mortality in critically ill onco-hematology patients admitted to the ICU for septic shock.
Project description:We found that a dose of influenza (5,000 pfu of recombinant influenza A/WSN/33 (rWSN) H1N1 virus strain) that resulted in 50% mortality in wildtype littermate control mice showed minimal mortality in Irgm1-/- mice, indicating that Irgm1 deficiency was protective during influenza infection. This protective effect was dependent on the Type I interferon receptor Ifnar. We performed transcriptional profiling to identify molecular mechanisms associated with protection from influenza infection in Irgm1-/- lung. Both male and female mice were used at 8-12 weeks of age. Lung gene expression was assessed by RNA-seq at the following times post-influenza infection: Day 3 (early time point, early histological damage present in control mice), Day 6 (intermediate time point, late histological damage present in control mice) and Day 10 (late time point, morbidity and mortality present in control mice).
Project description:Longitudinal Gene expression profiling of whole blood from critically ill influenza and bacterial pneumonia patients. In addition before vs 7 days post influenza vaccination volunteer samples are assayed. 3 groups of samples. First is bacterial pneumonia patients with 6 subjects sampled for up to 5 days. Second group is severe influenza infection with 4 subjects sampled for up to 5 days. Third group is influenza vaccination with 18 subjects sampled before and 7 days post vaccination.
