Respiratory IgE-sensitization to innocuous antigens increases the risk for developing diseases such as allergic asthma.
The expression pattern of FcεRI on DC and basophils differentiates asthmatic from non-asthmatic atopic children
Dysregulated expression of IFN-dependent pathways after respiratory viral infections is a defining immunophenotypic feature of AVB-susceptible infants
Pregnancy is associated with an alternatively activated phenotype of alveolar macrophage before infection
This protocol adapted an experimental animal model of disease for sensitization to ovalbumin during the immediate post-weaning period beginning at 21 days of age
Food allergy affects up to 10% of Australian infants. It was hypothesized that if parents follow the Australasian Society of Clinical Immunology and Allergy guidelines, Australian food allergy rates may stabilize or decline.
Malaria is a deadly disease caused by Plasmodium spp. Several blood phenotypes have been associated with malarial resistance, which suggests a genetic component to immune protection.
Despite vaccination, influenza and otitis media (OM) remain leading causes of illness. We previously found that the human respiratory commensal Haemophilus haemolyticus prevents bacterial infection in vitro and that the related murine commensal Muribacter muris delays OM development in mice. The observation that M muris pretreatment reduced lung influenza titer and inflammation suggests that these bacteria could be exploited for protection against influenza/OM.
IgE-mediated sensitisation to egg is common in infants. In some cases, the processes leading to egg sensitisation are established in early life, even before introduction to solid foods. The underlying mechanisms remain poorly understood.
Impaired interferon response and allergic sensitization may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells play a key role in antiviral immunity as critical producers of type I interferons.
