LPS binding protein and activation signatures are upregulated during asthma exacerbations in childrenAsthma exacerbations in children are associated with respiratory viral infection and atopy, resulting in systemic immune activation and infiltration of immune cells into the airways. The gene networks driving the immune activation and subsequent migration of immune cells into the airways remains incompletely understood. Cellular and molecular profiling of PBMC was employed on paired samples obtained from atopic asthmatic children during acute virus-associated exacerbations and later during convalescence.

Stiffness Mediated-Mechanosensation of Airway Smooth Muscle Cells on Linear Stiffness Gradient HydrogelsIn obstructive airway diseases such as asthma and chronic obstructive pulmonary disease (COPD), the extracellular matrix (ECM) protein amount and composition of the airway smooth muscle (ASM) is often remodelled, likely altering tissue stiffness. The underlying mechanism of how human ASM cell (hASMC) mechanosenses the aberrant microenvironment is not well understood.

Airway smooth muscle thickness and contraction are enhanced by intra-amniotic lipopolysaccharide in an ovine model of premature birthAbnormalities of the airway smooth muscle (ASM) layer in asthma may develop before birth. We hypothesize that antenatal inflammation causes physiological abnormalities of the ASM that predisposes asthma. This study determined the short-term effects of antenatal inflammation on the developing ASM.

Febrile respiratory illnesses in infancy and atopy are risk factors for persistent asthma and wheezeThe aim of this study was to explore associations between severe respiratory infections and atopy in early childhood with persisting wheeze and asthma.

Defective function at the epithelial junction: A novel therapeutic frontier in asthma?The airway epithelium forms a highly regulated physical barrier that normally prevents invasion of inhaled pathogens and allergens from the airway lumen.
