High risk for virus-induced asthma exacerbations in children is associated with an IRF7lo immunophenotype, but the underlying mechanisms are unclear. Here, we applied a Systems Biology approach to an animal model comprising rat strains manifesting high versus low susceptibility to experimental asthma, induced by virus/allergen coexposure, to elucidate the mechanism(s)-of-action of the high-risk asthma immunophenotype.
Intrauterine growth restriction (IUGR) is associated with asthma. Murine models of IUGR have altered airway responsiveness in the absence of any inflammatory exposure. Given that a primary feature of asthma is airway inflammation, IUGR-affected individuals may develop more substantial respiratory impairment if subsequently exposed to an allergen. This study used a maternal hypoxia-induced mouse model of IUGR to determine the combined effects of IUGR and allergy on airway responsiveness.
Climate change models predict that atmospheric carbon dioxide [CO2] levels will be between 700 and 900 ppm within the next 80yrs. In this study we aimed to assess the respiratory structure and function effects of long-term exposure to 890ppm CO2 from preconception to adulthood using a mouse model.
Findings provide further proof of concept that pharmacological targeting of airway smooth muscle thickness will be beneficial and may be facilitated by azithromycin
This study tested the utility of optical coherence tomography-based indentation to assess mechanical properties of respiratory tissues in disease
In this study, we aimed to use microRNAs-which are critical regulators of signaling cascades-to identify so far uncharacterized asthma pathogenesis pathways
