(Submitter supplied) Allergic (Th2high immunophenotype) asthmatics have a heightened susceptibility to common respiratory viral infections such as human rhinovirus. Evidence suggests that the innate interferon response is deficient in asthmatic/atopic individuals, whilst other studies show no differences in antiviral response pathways. Unsensitized and OVA-sensitized/challenged Th2high (BN rats) and Th2low immunophenotype (PVG rats) animals were inoculated intranasally with attenuated mengovirus (vMC0). more...

(Submitter supplied) Severe asthma exacerbations in children requiring hospitalisation are typically associated with viral infection, and occur almost exclusively amongst atopics, but the significance of these comorbidities is unknown. We hypothesised that underlying interactions between immunoinflammatory pathways related to responses to aeroallergen and virus are involved, and that evidence of these interactions is detectable in circulating cells during exacerbations. more...

Analysis of peripheral blood mononuclear cells of children with acute asthma during exacerbation and at subsequent convalescence. Severe asthma exacerbations in children are associated with viral infection and occur among atopics. Results provide insight into the significance of these comorbidities.

(Submitter supplied) Viral-induced severe asthma exacerbations in children are characterized by IRF7hi and IRF7lo molecular phenotypes. We have developed an experimental animal model that mirrors these response patterns in asthma-resistant PVG and asthma-susceptible BN rats respectively. We aimed to i) characterize the immunological and molecular hallmarks of PVG and BN responses to virus/allergen exposure, and (ii) evaluate the utility of innate immune training with the bacterial lysate OM85 to attenuate ensuing inflammation. more...

(Submitter supplied) Asthma 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 (n = 19) during acute virus-associated exacerbations and later during convalescence. more...
