Childhood tolerance of severe influenza: a mortality analysis in mice.
Sex, Specimen part
View SamplesDuring the 1918 influenza pandemic, children experienced substantially lower mortality than adults, a striking but poorly understood finding. Whether this was due to enhanced resistance (reduced virus load) or better tolerance (reduced impact of infection) has not been defined. We found that prepubertal mice infected with H1N1 influenza virus also showed greater survival than infected pubertal mice, despite similar virus loads.

View SamplesTo investigate the early host response triggered by three different strains of Trypanosoma cruzi at a local infection site, changes in host gene expression were monitored in a murine intradermal infection model using Affymetrix oligonucleotide arrays. Robust induction of IFN-stimulated genes (ISGs) was observed in excised skin 24 hours post-infection where the level of ISG induction was parasite strain-dependent with the least virulent strain triggering a muted IFN response. Infection of mice immunodepleted of IFN-producing cells or infection of IFN-deficient mice had minimal impact on the IFN response generated in T. cruzi infected mice. In contrast, infection of mice lacking the type I IFN receptor demonstrated that type I IFNs are largely responsible for the IFN response generated at the site of infection. These data highlight type I IFNs as important components of the innate immune response to T. cruzi the site of inoculation and their role in shaping the early transcriptional response to this pathogen.

View SamplesAdiponectin is an adipose-derived hormone with anti-inflammatory activity. Following subacute ozone exposure (0.3 ppm for 24-72 h), pulmonary neutrophilic inflammation is augmented in adiponectin deficient mice. The purpose of this study was to use microarrays to examine the impact of adiponectin deficiency on changes in pulmonary gene expression induced by ozone, a common air pollutant.
Pivotal role of IL-6 in the hyperinflammatory responses to subacute ozone in adiponectin-deficient mice.

View SamplesObese mice have an augmented response to Ozone exposure (2 ppm for 3 hours and studied 24 hours later), including increase airway hyperresponsiveness and BAL inflammation when compared to WT ozone exposed mice. When IL-17A is block with systemic injected of IL-17A antibodies there is a decrease of response in the obese mice. To determine the mechanism of action, RNA was extracted from the lungs of IL-17A and Isotype injected ozone exposed obese mice and microarray analysis of gene expression was performed.

View SamplesObesity-associated metabolic complications are generally considered to emerge from abnormalities in carbohydrate and lipid metabolism, whereas the status of protein metabolism is not well studied. Here, we performed comparative polysome and associated transcriptional profiling analyses to study the dynamics and functional implications of endoplasmic reticulum (ER)-associated protein synthesis in the mouse liver under conditions of obesity and nutrient deprivation.

View SamplesFollowing the identification of a critical time window of Blood Brain Barrier formation in the mouse embryo, we aimed to identify genes important for barriergenesis. To this end, we isolated cortical and lung E13.5 endothelial cells and compared expression between the two populations.
