Allergic sensitization and reduced ability to respond to viral infections may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells (pDC) are rare immune cells that produce type I interferons (IFN-I) and play a key role in orchestrating immune responses against viruses.
Asthma affects more than 300 million people worldwide and is frequently associated with other medical conditions in adults, including chronic obstructive pulmonary disease, ischaemic heart disease, and stroke. Despite the huge burden, there has been little progress toward prevention and cure, possibly related to a one-size-fits-all approach.
Asthma affects > 10% of children in Australia and New Zealand (NZ), with up to 5% of those having severe disease, presenting a management challenge. We aimed to survey tertiary paediatric respiratory services across Australia and NZ using a custom-designed questionnaire, to conduct a cross-sectional observational study of the numbers of children with problematic severe asthma seen, the number treated with biologic therapy, outpatient clinic/multidisciplinary team services available, investigations and tools routinely used and approaches utilised for transition to adult care.
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.
The airway epithelium in asthma displays altered repair and incomplete barrier formation.
Activation of receptors of the innate immune system is a critical step in the initiation of immune responses.
The extent to which maternal smoking in pregnancy (MSP) has persisting effects on respiratory health remains uncertain and the mechanisms involved are not...
To compare IgE and IgG antibody binding and T-cell recognition of the major cat allergen Fel d 1 with other cat proteins with known IgE binding properties.
Breastfeeding is recommended for all infants irrespective of atopic heredity, although epidemiological studies provide conflicting results in this debate.
In healthy individuals, deep inspirations (DIs) taken prior to a bronchial challenge reduce the bronchoconstrictor response, which is termed...
